Problem Cause Solution
Mouse Not
Responding*

Unplug the mouse from the Switch, then plug it
back in.
Switch needs to be
reset
Turn off the PCs. Wait 5 seconds; then turn the
PCs on.
Wrong type of mouse
or adapter
The switch will only work with a PS/2 mouse. A
serial mouse cannot be converted to a PS/2
mouse by using a serial to PS/2 adapter. One
exception is a combo-mouse which is specifically
designed for both applications. In this case,
ensure that the mouse is set up for PS/2 mode
and is being used with the adapter originally
provided.
Unsupported or
incorrect mouse
driver
Each PC needs to be using the mouse driver
correlating to the mouse connected to the
console port.
Some newer mice (with extra buttons and wheels)
have unique drivers that may not be supported.
Try a regular mouse with a generic mouse driver
(like the one that comes with the operating
system).

* Some notebook computers, notably the IBM® Thinkpad® and Toshiba® Tecra®, have trouble working with a
switch when their mouse and keyboard ports are used simultaneously. To avoid this problem, only connect
the mouse port or the keyboard port to the switch. If you connect the mouse port, you will need to use the
notebook’s keyboard when the notebook is the active computer. These switches are designed to work with
PS/2 keyboards. Older XT (84 key) and AT keyboards will not work.
7. Troubleshooting
If you are experiencing problems, first make sure that there are no cable
problems. Check all cable connections.
