TROUBLESHOOTING

ULTRACONSOLE INSTALLATION AND OPERATIONS MANUAL 43

Troubleshooting

Computer does not boot, keyboard or mouse error received

 CPU cable is loose. Re-seat cable and hit F1 to continue or reboot computer.

 Wrong cable plugged in. Keyboard and mouse cables reversed.

 CPU cable is defective. Try using CPU cable from another computer. If problem goes away, cable is defective.

 Port on UltraConsole is defective. Try using another port on the UltraConsole. If problem goes away, port is

defective.

 Port on computer is defective. Try plugging in keyboard or mouse directly. If problem remains, computer port is

defective. If computer power status LED not lit, fuse on motherboard may be blown.

Mouse driver does not load

 If PS/2 type mouse, computer must be attached to the UltraConsole or mouse at boot-up time in order for mouse

to be recognized by the computer. Reboot computer with the UltraConsole powered on and a CPU cable

attached.

 Incompatible or old mouse driver being used. Update mouse driver.

Can’t switch computer port from keyboard

 Power to the UltraConsole was removed for less than three seconds possibly causing keyboard to lock up.

Detach and reattach keyboard.

 The mode of the keyboard does not match that of the computer. Issue the mode command, usually 1 for IBM

PS/2s, and 2 for all others. The default setting of the UltraConsole is mode 2. Sometimes an incorrect mode will

confuse the computer or keyboard. This requires re-booting the computer or resetting the keyboard by

unplugging and plugging it back in.

 If trying to reach a remote port, that port is busy. Try again later.

 If trying to reach a remote port, the expansion cable is detached or the remote Unit is powered off.

 Keyboard port or computer port cable detached.

Wrong or missing characters from those typed

 The keyboard mode is incorrect; configure computer port for correct keyboard mode.

Mouse does not move

 The UltraConsole turned off after or not attached when computer booted or application began using mouse. Exit

and re-enter application using mouse or issue reset command.

 PS/2 mouse was not attached when the UltraConsole powered up or has been detached and reattached. Issue

the reset command.

PS/2 mouse gets out of sync

 Reset the mouse by pressing and releasing the left Control Key, and then the R key.

 Cabling was disturbed during mouse movement. Issue the null command once or twice to re-sync the mouse.

Get a later mouse driver that does not exhibit this problem.

Video fuzzy

 Cable too long or wrong type. Verify that resolution and distance match Appendix I – Video Quality Chart

Upgrade cable if necessary.

Video not synchronized or wrong color

 Cable is loose. Re-seat cable.

 Wrong computer (CPU) cable used. If you have a 9515, 9517, 9518, XGA mono or similar monitor you must use

special cables or adapters.

 Cable is defective. Try using cable from another computer (CPU). If problem goes away, cable is defective.

 Port on the UltraConsole is defective. Try using another port on the UltraConsole. If problem goes away, port is

defective.

Lower resolution video OK, but can’t enter high resolution mode

 Wrong CPU cable used. If you have a XGA, XGA-2, or other high-resolution video adapter, you should probably

be using the CAB-CX (or C1) cable to attach your computer and KVM station.

 Driver has not been setup. Windows, OS/2, or other driver has not been configured for this resolution. Configure

the driver.
