CHAPTER 5: Operation
5.9 Hot-Plugging a PS/2 Mouse or Mouse Port into the Extender or
Re-Enabling a Disconnected PS/2 Mouse Port (KV6EXT-R2 with Local CPU
Only)
It is advisable to switch off any local computer that you’re going to connect to the
full KV6EXT-R2 ServSwitch Duo Extender before you install it. However, even if
this is not possible, most systems can be “hot-plugged” (connected to the Extender
while they are powered and operating); the PS/2 mouse-port malfunctions this
usually causes can often be overcome by using the Extender’s mouse-restoration
functions. (The keyboard connection will normally restore itself automatically.)
Let’s take this from the top: On many PCs, mouse movement will be lost if the
PS/2 mouse is unplugged and plugged back in while the PC is running. Mouse
movement can then be restored only by rebooting the PC. This is because the
mouse drivers only set up and enable the mouse when the PC is initially booted.
If you have powered down your Extender, or if you are attempting to hot-plug a
CPU into it, you might be able to restore lost mouse movement using the
Extender’s mouse-restoration functions. These should be used with caution,
because unpredictable results might occur if you select the wrong mouse type. If in
doubt, restore the mouse by rebooting the PC normally.
Standard PS/2 mouse data is formatted differently than IntelliMouse data, so
two reset functions are provided on the Extender. The type of data format
expected by the PC depends on the driver and the type of mouse that was
connected when the driver was booted. You can use the following table as a guide;
note that the mouse-reset functions predict the likely mouse
