I have a Digital Alpha running UNIX and want to use a standard PS/2 keyboard. How will that affect operation with my switch?
Merely connect a Raritan converter (AUKME) to any Alpha running UNIX and all computers will operate flawlessly with a standard PS/2 keyboard.


I have a Digital Alpha running UNIX and another running OpenVMS which use a special LK111 or LK461 keyboard. How will that affect operation with my switch?
The Alphas will operate flawlessly. Raritan's emulation incorporates unique functions to support LK111 or LK461 keyboard running UNIX and OpenVMS.


I have Suns and/or Macs in addition to PCs. Can I control them all from a single keyboard, mouse, and monitor?
Yes. Use Raritan's Sun or Mac Guardian converter (APSSUN or APSMAC) to convert the Sun and Mac keyboard and video ports to PS/2 keyboard and mouse and VGA video. APSSUN includes the built-in mapping of all the Sun L-keys to PS/2 F-keys.


I have a serially controlled device (i.e. Unix server, hub). Can I use my KVM switch to access and control this device?
Yes. Raritan's ASCII Terminal Converter (AUATC) adapter will convert the RS-232 connection to PS/2 and VGA video. Connect the AUATC to your serially controlled device, and then connect to your Raritan KVM switch with CCPdd or UTP Cable for access up to 650 feet.


I just received a Raritan product and I need help installing it. Where can I go to get help?
Raritan's technical support group can provide you with assistance over the phone or via e-mail. It does not make any difference where you purchased your product; Raritan will provide technical support. Please have your packing slip handy to verify the parts you received. Also, a general knowledge is very helpful to you when calling, so take a few minutes to familiarize yourself with the installation manual.


Can I use a trackball keyboard?
You can plug any PS/2 keyboard in the keyboard user port of a Raritan KVM switch.


I noticed that one of the servers connected to my Raritan KVM switch does not display the correct colors on my monitor. Does my KVM switch have a bad channel?
Probably not. That particular server may have a unique video card that is not of the 8514 type. Pin modification to the KVM switch cable video connector can be made to correct the problem. Refer to Technical Notes in the Manual for your particular Raritan KVM switch model, or call Raritan's Technical Support for assistance.

What are the monitor resolution and refresh rates for Raritan KVM switches?
All Raritan KVM switches except SwitchMan operate up to 1600 x 1200 at 60Hz. SwitchMan operates at 1600 x 1200 at 70Hz.


Can I use a touch-screen monitor with my Raritan KVM switch?
No. Most touch-screen monitors use a serial connection to interact with the PC. Currently, Raritan's KVM switches do not support the use of this style monitor.


How do I connect a PC with a DB9 serial mouse port to a Raritan KVM switch?
The CCPdd cable comes with an adapter to convert the 6-pin mouse connection to 9 pin. The conversion of serial to PS/2 mouse is handled by the firmware in the KVM switch.


My mouse seems to be erratic and jumps around opening windows. What's happening?
There is a possibility that the proper mouse driver is not loaded or the mouse is not recognized. Check to make sure the mouse driver is correct for the mouse type you are using. MasterConsole must have a true PS/2 mouse connected; serial and bus mice are not supported as device peripherals.


Is there any software requirement for PCs connected to a Raritan KVM switch?
No. The Raritan KVM switch does not require any software to be loaded or operated, it is 100% software independent.


My computer has USB connectors. Can I connect it to a Raritan KVM switch?
Yes, plug a APSUSB adapter into one of the USB computer ports to convert PS/2 keyboard and mouse. Plug the KVM switch cables into the APSUSB and access your USB computer just like a PS/2 PC.

Is there any software requirement for PCs connected to Dominion SX?
No. The Dominion SX does not require any software to be loaded or operated; it is 100% software independent.


How can I consolidate the sites where I have a Dominion SX installed?
Raritan's CommandCenter is designed specifically to provide centralized management. It is the ideal solution if you are looking to consolidate management of devices such as Dominion SX and other Raritan network-based products.


Is Raritan new to the secure console server market?
No. On the contrary, Raritan has been in the secure console server business for about 1.5 years, following the acquisition of Arula Systems from Hewlett-Packard (***verify date & corporate ownership of Arula).


Will there be other models in the Dominion SX family?
Yes. Additional models of the Dominion family will be available in the future.


Is the Ethernet port on the Dominion SX unit 10/100Mbps auto sensing?
Yes


Does Dominion SX support RS422 and RS485?
No currently Dominion SX supports only asynchronous RS232 (also commonly called serial, even though serial is a broad term that covers more than RS232). RS 422 and RS485 are used in industrial automation and other markets. Dominion SX is currently designed for connection to serially managed servers and other devices typically found in the data-center and server rooms. This includes serially controlled power strips like Raritan's line of remote power control units.


Do I need to be a Unix expert to sell or install a Dominion SX?Is it easy to install?
Not at all. Dominion SX is the easiest to install of all the secure console servers on the market. From power-up, typical time for installation is less than 3 minutes, with no need to edit files and use the command-line. Dominion SX does not require an external server to operate.


I have a server/serially managed device that is more than 300 feet from the Dominion SX -how do I connect?
You will need to purchase a 3rd party RS232 to RS422/485 converter for each end (two units total)-one at the Dominion end and one connected to the device.


Does Dominion SX provide an integrated interface that allows you to view all the Serial devices that are connected?
Yes, Dominion SX provides a single, consolidated view of all serial devices via one-sign-on. A single IP address gives access to all connected serial devices while any Java-enabled Web browser provides VT100/ANSI terminal emulation.


Can I open multiple windows and "tile" to monitor multiple servers and other IT equipment?
Yes, you may monitor and "tile" as many windows as there are serial ports on the Dominion SX. For example, up to 32 serial ports per Dominion SX32 unit.


I manage many servers. How do I select a server to connect to?
A simple menu provides the user-assigned name of each server. Users simply click on a server to connect to its console port.


As a user, do I see all servers connected to a Dominion SX?
No. Each user sees only a list of servers they are authorized to manage/view. The administrator of the Dominion SX sets up the access privileges to each server.


Does Dominion SX work with Raritan's CommandCenter™?
Yes, Dominion SX is deployable as part of an enterprise-wide network management solution with Raritan's CommandCenter™.


Is the modem used only for administering the Dominion SX itself?
Unlike almost every other product in its category, Dominion SX offers modem access to administer the box AND get to the target servers.


Is a modem standard on any Dominion SX models?
Dominion SX Models with 16 or more serial ports include a built-in 56K modem. There is no additional charge for this modem. Competitors charge for an additional PCMCIA modem. Other models have a dedicated modem port via a DB9-Male connector.


What level of control does Dominion SX have over attached target servers?
The remote user has direct command line access and total control of target devices for maintenance, administration, troubleshooting, and even rebooting. User rights are only restricted by their log-on privileges on Dominion SX and the server itself.


What is the MTBF for the power supply in the Dominion SX?
350,000 hours. But, keep in mind that the life of a power supply depends on environmental factors like temperature, humidity, variation in power, and other factors.


What is the ESD (electro-static discharge) protection on the Dominion SX serial ports?
15KV (Kilo volts)


Why do I need to use a serial adapter to connect to some servers?
While EIA published a standard for RS232 on DB25 and DB9 connectors, there is no standard for RS232 on RJ45. Also, some manufacturers have chosen not to follow the pin out assignments of the EIA.


Is the Dominion SX unit SUN "break-safe"?
All Dominion SX units are SUN "break-safe" for use with SUN Solaris.


I have lost my Admin password to the Dominion SX. Is there a back door or secret password?
For security reasons, Dominion SX does not have any factory default username or password. There is no back-door password. The only option is to restore the unit to its factory default settings and create the Admin username and password again. A hardware reset function to restore the unit to factory default facility is provided.


Does Dominion SX include the 19" rack mount kit or is there an extra charge for this option?
Dominion SX comes standard with a complete ready-to-install 19" rack mount kit on the models with 16 or greater serial ports. Some competitors charge extra for a rack mount kit. On models with less than 16 ports a rack mount kit is available as an option.


What remote access connection methods can Dominion SX accommodate?
Dominion SX provides multiple choices for remote access. These include: Internet, LAN/WAN, or dial-up modem. That means servers can be accessed both in and out of band so remote access to mission critical target servers is always available-even if the network is down.


Which ports need to be open on the corporate firewall for a secure console session using Dominion SX?
Port 443 (for https); optionally port80 (http) for user sessions. Also, either port 23 or a user-designated port between 2000 and 2400.


How do I get access to the Command Line Interface (CLI) of the Dominion SX?
Dominion SX is a secure appliance. Therefore, NO access is possible to the CLI.


I have a few serial devices located a distance away from my server closet and the Dominion SX. Can I connect these devices to my Raritan switch?
Yes. EIA RS232 specifications defined in the 1970s recommend that the maximum distance serial devices be 30 feet (10 meters). However, with good cables and low baud rates, customers report success up to 200 feet.


How do I upgrade the software on my Dominion SX?
Use the Administrator option for Upgrade from a menu. The upgrade is done over the Ethernet port of the Dominion SX.


Are updates to Dominion SX software free?
Yes. Currently all software upgrades are free.


Does Dominion SX require any additional client software?
No. Dominion SX is truly "Plug-and-Play" making installation quick and set-up easy. It is not necessary to buy any additional client software or hardware. In addition, no special networking equipment or design is necessary.


What code-sets does the terminal emulator in Dominion SX support?
Dominion SX supports VT100/ANSI with the following code-sets:
  • US-ASCII ((ISO 646)
  • ISO 8859- (Latin-1)
  • ISO-8859-15— (Latin -9)



What is the name of the terminal emulation package included with Dominion SX?
RaritanConsole


Can I use Dominion SX over a VPN connection?
Yes, Dominion SX fits into most any network configuration utilizing TCP/IP. Set up the VPN (typically IPSec) connection then start the web-browser and enter the URL for the Dominion unit. The session to the Dominion runs transparently over the VPN tunnel.


The Dominion SX uses the Web to access serial devices. What are the advantages of Java-enabled Web browser access?
For many Solaris/Unix/Linux system administrators, the de facto standard for accessing serial hosts is SSH. However, the SSH clients available for Unix/Linux do not support Apple Macintosh. Additionally, Java-enabled browsers are available on many platforms, including PDAs and handheld PCs. The easy "point-and-click" access offered by Dominion SX allows administrators secure access from any Java-enabled Web browser.

All UMT II switches have a network port for firmware upgrades. Each unit can be assigned an IP Address and is recognized by the UMT Manager software via the network.


Will UMT II work with my current UMT installation?
Yes. The new UMT switch is backwards compatible with older UMT components. Please consult the UMT II manual for configuration and compatibility guidelines.


I have Suns and/or Macs in addition to PCs. Can I access and control them all with UMT II?
Yes. The UMT II User Station has built-in ports for PS/2, Sun, or USB keyboards and mice. Use Raritan's SUN or Mac adapters to convert keyboard and video ports to PS/2 keyboard/mouse and VGA video.


I have a Digital Alpha running UNIX and another running OpenVMS which use a special LK111 or LK461 keyboard. How will that affect operation with my switch?
The Alphas will operate flawlessly. Raritan's emulation incorporates unique functions to support LK111 or LK461 keyboard running UNIX and OpenVMS.


I have a Digital Alpha running UNIX and want to use a standard PS/2 keyboard. How will that affect operation with my switch?
Merely connect a Raritan converter (AUKME) to any Alpha running UNIX and all computers will operate flawlessly with a standard PS/2 keyboard.


I have a serially controlled device (i.e. Unix server, hub). Can I use UMT II to access and control this device?
Yes. Raritan's ASCII Terminal Converter (AUATC) adapter will convert the RS-232 connection to PS/2 and VGA video. Connect the AUATC to your serially controlled device, then connect to your UMT II switch with UTP Cable for access up to 1000 feet.


What is "Integrated Power Management"?
Integrated Power Management is a single, consolidated view (and control of) Raritan Remote Power Control Units connected to UMT II.


So I can access and control all my connected Power Units via the UMT II OSD?
Yes! UMT II lets you control power to any connected device, set security permissions on a per-outlet basis, recycle power to multi-power supply servers, and get status information from each connected strip.


UMT II is a stackable switch. Does this mean that I can stack logical units to increase the number of ports available?
Yes. UMT II provides a stacking capability that eliminates the need to run cable between logical 'tiers' and instead uses only a single stacking cable.


I would like to eliminate all the cables between cascaded UMT units. Can I do this?
Yes, with UMT II you get exclusive stacking capability that allows you to increase port density to 128 ports per switch


Is the stacking cable that connects base and expansion units together common to all UMT II switches?
Yes, the stacking cable is common to all UMT II switches.


What is the maximum length of the stacking cable?

CommandCenter

Is the status of CommandCenter limited by the status of the devices which it proxies?
No. Because CommandCenter software resides on a dedicated server, even if a device being proxied by the CommandCenter is turned off, you will still be able to access CommandCenter.


Can I upgrade to newer versions of CommandCenter software as they become available?
Yes. Contact your authorized Raritan sales representative or Raritan Computer directly at 1-800-724-8090 for details.


How many login accounts can be created for CommandCenter?
There is no specified limit to the number of login accounts that can be created for CommandCenter, but the number is not limitless. The size of the database, the performance of the processor, and the amount of memory on the hosting server will determine how many user accounts can actually be created. These user accounts can be any combination of Administrators and Operators with at least one Administrator account.


How many target devices (ports) and/or Dominion x16/x32 and/or IP-Reach units can be connected to CommandCenter?
There is no specified limit to the number of ports and/or Dominion x16/x32 and/or IP-Reach units that can be connected, but the number is not limitless: the performance of the processor and the amount of memory on the hosting server will determine how many ports can actually be connected.


Can I assign specific port access to a specific user?
Yes, if you have Administrator permissions. Administrators have the ability to assign specific ports per user.


Sometimes when I try to log in, I receive a message that states my "login is incorrect" even though I am sure I am entering the correct User Name and Password. Why is this?
There is a session-specific ID that is sent out each time you begin to login to CommandCenter. This ID has a time-out feature, so if you do not log on to the unit before the time-out occurs, then the session ID becomes invalid. Performing a Shift-Reload refreshes the page from CommandCenter. Similarly, you may close the current browser, open a new browser, and log on again. This provides an additional security feature so that no one can recall information stored in the Web cache to access the unit.


How is a password secure?
Passwords are encrypted using MD5 encryption, which is a one-way hash. This provides additional security to prevent unauthorized users from accessing the password list.


Is there any way to optimize the performance of Microsoft Internet Explorer if it is my preferred Web browser?
To improve the performance of Microsoft IE when accessing the console, disable the "JIT compiler for virtual machine enabled," "Java logging enabled," and "Java console enabled" options. From the main menu bar, select Tools > Internet Options > Advanced. Scroll down until you see the above items and make sure that they are not checked.


Sometimes I receive a "No longer logged in" message when I click on any Menu in CommandCenter, after leaving my workstation idle for a period of time. Why?
CommandCenter times each user session. If no activity happens for pre-defined period of time, CommandCenter logs the user out. The length of the time period is pre-set to 60 minutes, but can be reconfigured. It is recommended that users exit CommandCenter when they finish an operation.


An administrator added a new port to the CommandCenter database and assigned it to me, but I cannot see it in my Device Selection table. Why?
Ports assigned to you while you are logged in will not appear in your current Device Selection table. To update the table and see the newly assigned port, click on the [Refresh] button, but remember that refreshing CommandCenter will close all of your current console sessions.


The event times in the Audit Trail seem incorrect. Why?
Log event times are logged according to the time settings of computer that CommandCenter is installed on. You can correct this by adjusting the computer's time settings.


As a CommandCenter Administrator, I added over 500 ports and assigned all of them to me. Now it takes a long time to log on to CommandCenter.
When you, as Administrator, have many ports assigned to you, CommandCenter downloads all port information for all ports during the logging process, which slows the process considerably. It is recommended that Administrator accounts used primarily to manage CommandCenter configuration/settings do not have many ports assigned to them.


I want to add my existing Dominion serial console device to CommandCenter. How can I do this?
The Dominion can be easily addess by ensure\ing that the following conditions are met:
  • The Dominion unit is active.
  • The Dominion unit has a user account with arulacc/arulacc/cc12345 as its login_name/user_name/password.
  • The Dominion unit has not reached the maximum number of configured user accounts. For Dominion x1, Dominion x16 and Dominion x32, there cannot be over 48 configured user accounts.

MasterConsole

I don't want to use the "scroll lock" to activate hot-key. What are my options?
The hot-key activator can be easily changed to either "num lock" or "caps lock". When in hot-key mode, touch the desired new hot-key activator followed by the enter key.


We have some mission critical servers and there are occasions when we may wish to disconnect a server from the Raritan switch and "hot-plug" a physical keyboard and mouse to operate the server. Is that possible?
Yes. Simply plug Raritan's virtual keyboard/mouse (APKME) device into the server's keyboard/mouse ports and then plug the MasterConsole cable into the APKME's keyboard/mouse ports. APKME will provide constant keyboard/mouse signals to the server and you can "hot-swap" a physical keyboard and mouse for direct server operation, at any time.


On the back of my MasterConsole MX4 there is a port labeled, "Admin". What is it used for?
The Admin. port is used for flash upgrades of firmware using MCUpdate. The Admin. port is also used for OverView, an add-on, PC Windows program to maintain configuration data and real-time tracking of user activity.


If I am cascading MX4 units and only have a need for 2 users on the base unit, do I need all four paths to each cascaded MX4?
No. You only need to connect an equal number of paths from the base unit to a 2nd tier as you have users on the base unit needing simultaneous access to the 2nd tier.


My Sun server has a 15 pin VGA type connection (PGX video card). How do I connect it to my MasterConsole SMX?
SMX CCSnn cables have a 13W3(M) video connector, so you'll need to convert it to HD15. Use Raritan's 1396C {HD15(M) to 13W3(F)} adapter plugged directly into the Sun's video port and then connect the CCSnn 13W3 connector into it.


On the back of my MasterConsole II there is a port labeled, "Admin". What is it used for?
The Admin. port is used for flash upgrades of firmware using MCUpdate. On the MX4 and SMX, the Admin. port is also used for OverView, a software application running on a PC that tracks MX4 activity and optionally maintains the configuration data.


The RMT or 2ND light on the front of my MasterConsole II is always on. Is that normal?
If the unit is used as a tier, it is normal to have the 2nd light lit. To use this unit as a stand alone unit, or a base unit, power on the MasterConsole II while holding in the channel 4 button on the front panel (Channel 3 on the MCC models) This will initialize the unit as a stand-alone device. The RMT light should only be on when using a remote access kit containing a remote RKVM module and the remote user is active.


I have a MasterConsole II MCC model. Is it the same as my MCX or MCS model?
The MCC model replaces both the MCX and the MCS models. It is 100% compatible and can be cascaded with another MCC model or MCX or MCS model.

CompuSwitch

I see that the CompuSwitch has an AC power socket. Where does it get its power?
CompuSwitch gets its power from the keyboard port of the PCs connected. Raritan offers an optional, external 6V DC power supply which is recommended for cascading CompuSwitch units.


Can I cascade CompuSwitches to access and control more than 8 PCs?
Yes, CompuSwitch can be cascaded from base channel to cascade user port. An external power supply (DC6500U) is recommended for this configuration.

Back to Top
IP-Reach

What remote access connection methods can IP-Reach accommodate?
IP-Reach provides network administrators with a choice of remote access via Internet, LAN/WAN, or dial-up modem. That means servers can be accessed both in and out of band, so remote access to mission-critical target servers is always available--even if the network is down.


Can I customize IP-Reach to enhance performance relative to my specific KVM configuration?
Yes. A variety of fine-tuning procedures are available. Automatic Color calibration, KVM On-Screen Display tuning, and Target Mouse Pointer adjustments all serve to enhance IP-Reach performance.


Can I customize IP-Reach to enhance performance with regard to different remote access methods and situations?
Yes. IP-Reach offers a variety of performance enhancements to optimize a chosen connection method. Color Depth, Progressive Update, and Internet Flow Control are just a few of the adjustment options available to speed response time. Color Depth, for example, can be adjusted all the way down to black and white to decrease the data load during an emergency midnight modem connection to mission-critical servers over low-bandwidth.


Can I perform a dial-up modem connection to IP-Reach over a PBX line?
No. Modems require an analog telephone line.


How Is IP-Reach administration carried out?
Administrators access IP-Reach through a connected IP-Reach Admin Console. A simple keyboard driven interface of menus offers straightforward access to IP-Reach setup and control. User profiles, security settings, configuration and diagnostics are just a few of the options available. The IP-Reach Admin Console can be removed from the server room once IP-Reach setup is complete. Or for constant, clutter-free access to IP-Reach administrative menus from any location, IP-Reach can be designated as a Target to its KVM configuration.


Remote Access Software has been available for a long time. What makes IP-Reach different?
With IP-Reach, the software runs only on the IP-Reach unit itself, not on each individual Target Server. Traditional Remote Access Software solutions require software to be loaded and running on each Target Server, which must offer a supporting Operating System. This can create compatibility, performance, and reliability issues on mission critical Target Servers.


How does IP-Reach work?
IP-Reach connects to the keyboard, video, and mouse ports of a server or KVM switch. Using Raritan's powerful frame-grabber and compression technology, it captures, digitizes, and compresses the video signal before transmitting to a remote PC.


Is IP-Reach simple to install?
IP-Reach is very easy to install. Just connect it to a user port on an existing KVM configuration, and assign an IP address and/or telephone number for modem access. Run the short installation wizard for the Raritan Remote Client on your Remote PC, and you are ready for IP-Reach remote access.


What level of control does an IP-Reach remote user have over attached Target Servers?
The remote user has direct access and total control of target servers for maintenance, administration, and troubleshooting, from running GUI applications to BIOS-level troubleshooting, and even rebooting.


Can I continue to access my KVM configuration locally?
Yes. IP-Reach features a special Direct Analog User port for direct access to the KVM configuration. This pass through port provides an additional local access point, which is especially important for single-user switches or for providing critical access to servers if the network is down.


Can I use IP-Reach within my local network?
IP-Reach can be used in any computer network that supports TCP/IP (and UDP).


Can IP-Reach accommodate multiple remote connections at the same time?
IP-Reach TR364 and TR362 models enable 4 and 2 multiple user connections, respectively. In addition, up to 5 multiple users can remotely connect to IP-Reach and concurrently share control on a first active keyboard/mouse input status on each available channel.


Will other KVM switch brands work with IP-Reach?
Nothing complements IP-Reach better than a Raritan KVM Switch--especially UMT. In theory, however, IP-Reach can also be used with any KVM switch that features an On-Screen User Interface menu for access to switching functions.


Are there security features to protect my Target Servers from an unauthorized remote connection?
Yes. IP-Reach provides many layers of security. IP-Reach can be configured to provide high-level connection authentication and video data transfer security during a remote session. User names, passwords, private-keys, and Secure Socket Layer (SSL) 128-bit encryption are all available. IP-Reach can also function as a RADIUS client. In addition, all Raritan KVM Switches that feature an On-Screen User Interface (OSUI) come with a complete security scheme, requiring user name and password access to Servers as designated by the network administrator.


What is the slowest connection IP-Reach can handle?
IP-Reach offers scalable performance based on bandwidth available, down to 20kbps.


Is special software required for the remote PC?
Each IP-Reach ships with one copy of Raritan Remote Client software. This remote access software runs on any Remote PC with a Windows 98+ operating system and communicates over Internet, LAN/WAN, or dial-up modem with Raritan software on the IP-Reach unit. With this installed, the Remote PC is like any other user console in your KVM configuration, but it can be located anywhere 3/4 around the corner, or around the world.


What types of computers can IP-Reach remotely control?
IP-Reach works independently of a Target Server's hardware, operating system, or application software, accessing the Target Server's main input/output devices--keyboard, video, and mouse. Consequently, any hardware that supports standard PC keyboard interfaces, standard PC mouse interfaces, and standard PC video (VGA) can be used with IP-Reach. Currently, IP-Reach support is strongest for Windows-based Intel 86 servers, including HP, Dell, and Compaq. Sun support for certain Raritan KVM Switches is available with the proper Raritan converter products. ASCII devices can also be connected via Raritan's line of conversion products. IP-Reach does not support Macintosh.


Can IP-Reach be used without a KVM switch?
Yes. IP-Reach can be used to directly access individual computers, connected to the keyboard, video, and mouse ports of an independent computer. However, its convenience and value is leveraged through the use of a KVM switch.


What is IP-Reach?
IP-Reach is the easiest, fastest, most reliable way to remotely access and manage multiple servers connected to a Raritan KVM Switch--no matter where you are or where your servers are located.


Which Raritan KVM Switches will work with IP-Reach?
Currently Raritan supports the use of IP-Reach with all Raritan KVM Switches that feature On-Screen Display; UMT, MasterConsole MX4, and MasterConsole II.


Can I use IP-Reach in a VPN?
Yes. IP-Reach fits into most any network configuration utilizing standard TCP/IP. The network administrator simply adds IP-Reach as a node on the network via the IP-Reach Admin Console.

UMT

I have a Digital Alpha running UNIX and another running OpenVMS, which use a special LK111 or LK461 keyboard. How will that affect operation with my switch?
The Alphas will operate flawlessly. Raritan's emulation incorporates unique functions to support LK111 or LK461 keyboard running UNIX and OpenVMS.


I have Suns and/or Macs in addition to PCs. Can I control them all from my UMT UMT?
Yes. Use Raritan's Sun or Mac CIMs (USKVMC, USKVMP, or USKVMPA for Sun; AUPUSBC or UUSBPD for Mac) to convert the Sun and Mac keyboard and video ports to PS/2 keyboard and mouse and VGA video. The Sun CIMs include the built-in mapping of all the Sun L-keys to PS/2 F-keys.


On the back of my UMT UMT switch there is a port labeled, "Admin". What is it used for?
The Admin port is used for flash upgrades of firmware using UMT Update. The Admin port may also used for UMT OverView, a software application running on a PC that tracks UMT activity and optionally maintains the configuration data.


Can I use standard Ethernet (10BASE-T) cable?
No. Standard Ethernet cable does not have the necessary bandwidth characteristics for transmitting high-quality video over long distances.


Category 5e UTP is standardized. Why can't I simply use any Category 5e UTP cable with Raritan products?
Because the intended application of UTP cabling is the transmission of digital data, cable specifications are optimized for that application. However, because video data is by its very nature analog, Raritan's exclusive technology— which enables such high-bandwidth video information to be transmitted over relatively thinly-shielded Category 5e UTP, Category 6 UTP, or Category 7 UTP cables— requires even stricter tolerances for certain cable properties.

One particular UTP cable characteristic has a large impact on how well your Raritan system performs: delay skew. UTP cabling consists of four "twisted pairs" of wire, each carrying one set of data. In order to minimize cross-interference between the pairs, each pair must be twisted at slightly different rates (twists/foot). Over long lengths of cable, however, slight differences in twist rates result in measurably different rates of data transmission among each twisted pair. The arrival time delta is called "delay skew."

How does this affect your Raritan solution? Raritan products send red, green, and blue video information each over a different twisted pair; if that information does not arrive at the same time, observed video will be blurry. Raritan's unique algorithms correct for this behavior, but physical limitations create upper limits to the success of any algorithm.

The TIA/EIA specification for delay skew tolerance is 45 nanoseconds for Category 5 UTP and Category 5e UTP cable. However, in analog video applications, a delay skew longer than 15 nanoseconds usually results in inadequate video performance at high resolutions (XGA and higher).

Raritan-certified cable products happen to surpass the acceptable tolerances of the TIA/EIA's specification for delay skew, and hence are best suited for connecting Raritan components.


Can I use Category 6 UTP cable?
Yes. Currently only one Category 6 UTP cable product is Raritan certified for use with Raritan products. Raritan continues to test new Category 6 UTP cabling products as they are released to the market.


Can I use non-certified Category 5e UTP cable?
Yes, however, you may not get the same performance as you would with Raritan certified Category 5e UTP, Category 6 UTP, or Category 7 UTP cables. Using non-certified Category 5e UTP cable with Raritan products results in degraded video performance ranging from mildly irritating to severely unusable.

The only occasion when a non-certified cable may be used with Raritan products without negative effects on system usability is when the total cable distance between any user console and any connected device is less than 300 feet.

Because cable products certified by Raritan do not cost more than competing cable offerings, Raritan strongly suggests that users utilize Raritan certified cabling for maximum performance with Raritan product applications.


Can I use plain Category 5 UTP cable, instead of Category 5e UTP?
Yes, however, you may not get the same performance as you would with Raritan certified Category 5e UTP, Category 6 UTP, or Category 7 UTP cables. Standard Category 5 UTP cable may not have the necessary characteristics for transmitting high-quality video over long distances.


What UTP cable does Raritan recommend for use with the UMT UMT?
Raritan certifies the following Category 5e UTP and Category 6 UTP cable products for use with the UMT UMT.

Category 5e UTP:
  • Belden DataTwist 350 UTP— #1700A— Solid
  • Belden DataTwist 350 patch— #1752A— Stranded

Category 6 UTP:
  • Belden MediaTwist— #1872A— Solid

Use of non-certified cabling can result in video and data degradations that users may find unsatisfactory. The Raritan certified cable products listed above are widely available and competitively priced.

When using Raritan certified cable, users can transmit video signals at distances up to 1,000 feet at 1024 x 768 @75Hz, and up to 600 feet at 1600 x 1200 @75Hz.

(Note: Raritan does not have any marketing relationship with Belden, nor does Raritan receive any financial incentive for recommending Belden products.)


What happens if I do not use Raritan-certified cable?
Cable products that are not specifically certified by Raritan will not provide you with maximum performance and may cause your video to look blurry; in particular if the video signal is of high-resolution, or if the video signal must be transmitted over long distances. Furthermore, LCD monitors can become unusable.


What is the distance between cascaded units?
Cascaded UMT matrix switches can be up to 1,000 feet apart.


How can I get access to more servers if I have already connected computers to all my UMT UMT channel ports?
Cascade additional UMT matrix switches (UMT2161, UMT242, UMT442, UMT8, or UMT1664) to expand the capacity, up to 2,048 servers total.


I have some computers located more than 30 feet away from my UMT UMT. Can I connect these computers to my switch?
Yes. The maximum distance from the computers to users is 1000 feet.


I intend to place my switch in a rack or enclosed cabinet with the servers. Is there a simple way to switch and operate the servers from my desk without going to the rack?
Yes. The maximum distance from the computers to users is 1000 feet.


Can I have 2 unblocked paths to a 2nd tier UMT2161 unit in a cascaded configuration?
No. Although the UMT2161 has 2 user ports, one is intended for local user access.


Can I add Z-CIMs to a channel port on a UMT?
Yes. A chain of Z-CIMs can be added to a channel port of the UMT.


I don't want to use the "scroll lock" to activate the hot key. What are my options?
The hot-key activator can be easily changed through the User Profile screen of the On-Screen User Interface (OSUI).


We have some mission critical servers and there are occasions when we may wish to disconnect a server from the UMT UMT and "hot-plug" a physical keyboard and mouse to operate the server. Is that possible?
Yes. The UMT CIMs provide virtual keyboard/mouse protection. This provides constant keyboard/mouse signals to the server and you can "hot-swap" a physical keyboard and mouse for direct server access, at any time, without impact on server operation.


I just received a UMT UMT switch and I need help installing it. Where can I go to get help?
Please consult your UMT Quick Setup Guide or your UMT User's Manual. Raritan's technical support group can also provide you with assistance over the phone or via e-mail. It does not make any difference where you purchased your product; Raritan will provide technical support. Please have your packing slip handy to verify the parts you received. Also, a general knowledge is very helpful to you when calling, so take a few minutes to familiarize yourself with the installation manual.


Can I use a trackball keyboard?
You can plug any PS/2 keyboard in the keyboard user port of the UMT UMT switch.


Can I use a flat screen monitor?
The monitor needs to be VGA, with an HD15 connector, and support the resolution and refresh rate of the video settings on the target servers. Make sure the LCD monitor will work when connected directly to all the PCs in a stand-alone mode.


What are the monitor resolution and refresh rates for the UMT UMT?
The UMT UMT switch operates up to 1600 x 1200 @ 75Hz within 600ft; 1024 x 768 @ 75Hz within 1000ft.


Can I use a touch-screen monitor with my UMT UMT switch?
No. Most touch-screen monitors use a serial connection to interact with the PC. Currently, Raritan's KVM switches do not support the use of this style monitor.


Is there any software requirement for PCs connected to a UMT UMT?
No. The UMT UMT switch does not require any software to be loaded or operated; it is 100% software independent.


The video at my UST1 (User Station) is "fuzzy" or "out of focus". Why?
A video gain adjustment is available to allow the user to "focus" the video image. This adjustment is especially important when using flat screen LCD monitors. To adjust, activate the on-screen user interface (OSUI) by pressing the key twice rapidly, then using the < + > or <— > keys, adjust the video image until the image appears in focus.


My UST1 (User Station) monitor displays a message "No Connection to UMT". Why?
Please recheck all of your connections from the UST1 to the UMT UMT Matrix Switching Unit.


I'm encountering a continuous "Updating Please Wait..." message at the UST1 after updating the UMT UMT and UST1 firmware. Why?
The proper power cycling sequence for a UMT UMT tiered configuration is as follows:
1) tiered units;
2) base units;
3) UST1s.

When encountering this message loop, please power off all units and then restore power in the sequence listed above. If this doesn't clear the message please contact Raritan Technical Support for further assistance.


I need access to servers that may not be physically located in the same geographic area. Are there extended reach options for the UMT UMT?
Yes. Raritan's IP-Reach is the easiest, fastest, most reliable way to remotely access and manage multiple servers connected to a Raritan KVM Switch— no matter where you are or where your servers are located. The remote user has direct access and total control of target servers for maintenance, administration, and troubleshooting, from running GUI applications to BIOS-level troubleshooting, and even rebooting.


I have a serially controlled device (i.e. Unix server, hub). Can I use my UMT UMT switch to access and control this device?
Yes. Raritan's ASCII Terminal Converter (AUATC) adapter will convert the RS-232 connection to PS/2 and VGA video. Connect the AUATC to your serially controlled device, then connect to your Raritan UMT UMT switch with UTP cable.


My computer has USB connectors. Can I connect it to my UMT UMT switch?
Yes, plug a UUSBPD CIM into one of the USB computer ports to convert PS/2 keyboard and mouse. Plug UTP cables into the UUSBPD and access your USB computer just like a PS/2 PC.
