CHAPTER 6: Troubleshooting
Problem:
Your keyboard does not function or functions only intermittently. The Num Lock
LED does not always light when the Num Lock key is pressed.
Possible Solution:
Some older keyboards were designed for use with specific computers and are not
truly PC/AT or PS/2 compatible. These are not common, but if you’re having
problems like this and you’re using an old keyboard, try a newer keyboard.
Problem:
Just using your mouse normally causes the CPU channel to change unexpectedly.
Possible Solutions:
Some cheaper mice are not fully compatible with the Multi-Head ServSwitch and
can lose data, which—if mouse switching is enabled (see Section 4.2.5)—
sometimes causes the Switch to interpret a data stream as a channel-change
request. Try using a Microsoft, Logitech, IBM, Compaq
®
, or Hewlett-Packard
®
mouse instead.
Make sure that you are using a Microsoft compatible mouse driver on your PC.
Some drivers by other manufacturers can cause the mouse to use proprietary
mouse-data formats that the Switch doesn’t support. If you have unplugged and
reconnected a mouse to the Multi-Head ServSwitch, make sure that you reset it
(see Section 5.7) or—especially if the mouse is an IntelliMouse—use the mouse-
restoration function (see Section 5.8).
Problem:
The mouse moves very slowly but otherwise functions correctly.
Possible Solutions:
Change to a Microsoft mouse driver or set the Switch to the “L6” configuration
option. See Section 4.2.4.
Problem:
The cursor/pointer jumps around the screen after you disconnect the mouse cable
or power down the Multi-Head ServSwitch.
Possible Solutions:
If you have disconnected and reconnected a CPU mouse cable or you have
powered down the Multi-Head ServSwitch, and you’re using a PS/2 mouse or
IntelliMouse, the mouse might have gotten out of sync with the CPU. Try the
mouse-reset function (see Section 5.7) or the mouse-restoration function (see
Section 5.8), or reboot the CPU.
