2.7 Re-enabling a disconnected PS/2 mouse
If you disconnect the shared PS/2 mouse from the LINDY CPU Switch Junior by accident during
operation then the mouse operation will be lost when the mouse is plugged back in. To avoid
having to reboot the entire system in this situation the LINDY CPU Switch Junior is fitted with an
automatic mouse recovery system.

With the PS/2 mouse disconnected, change the channel using the keypad or keyboard hotkeys.
The LINDY CPU Switch Junior detects that the mouse has been disconnected and triggers the
automatic recovery system. Plug in the PS/2 mouse and the LINDY CPU Switch Junior will re-
initialise it.
You may also re-enable a disconnected PS/2
mouse by using the keyboard and mouse reset
function (see section 4.3). **
You can reset the keyboards and mice by
holding down the front panel key for 5
seconds. When the character ‘C’ is displayed
on the front of the LINDY CPU Switch Junior
OSD, press the front panel again. **
** A complete power off reset of the connected keyboards and mice will then be performed. This
function only resets the shared keyboard and mice that are plugged into the control port. It does
not affect the status of any of the other ports on the switch or the CPU connections.
2.8 Hot plugging the LINDY CPU Switch Junior into running systems and
re-enabling disconnected CPU PS/2 mouse connections
It is advisable to switch off the systems that are going to be connected to the LINDY CPU Switch
Junior before installation. However if this is not possible then most systems can be hot plugged by
using the LINDY CPU Switch Junior’s mouse restoration functions. The keyboard connection will
normally restore itself automatically.
On many PCs, mouse movement will be lost if the PS/2 mouse is unplugged and plugged back in
whilst the PC is running. Mouse movement can then only be restored by rebooting the PC. This is
because the mouse drivers only setup and enable the mouse when the PC is initially booted.
If you have switched off your LINDY CPU Switch Junior or you are attempting to ‘hot plug’ it into a
system that is already running, you may be able to restore lost mouse movement using the LINDY
CPU Switch Junior's mouse restoration functions.
IMPORTANT NOTE
Mouse restoration functions should be used with care as unpredictable results may occur
if the wrong mouse type is selected. If in doubt restore the mouse by powering down the
PC normally.
Standard PS/2 mouse data uses a different data format to IntelliMouse data and so two reset
functions are provided on the LINDY CPU Switch Junior. The type of data format expected by the
PC depends upon the driver and the type of mouse that was connected when the driver was
booted. The following table may be used as a guide. Note that the mouse reset functions predict
the likely mouse resolution settings but may not restore the speed or sensitivity of the mouse
exactly as they were when the PC originally booted.
