SERVSWITCH™ WIZARD MP
5.8 Re-Enabling a Disconnected PS/2 Mouse
If you accidentally disconnect the shared PS/2 mouse from the ServSwitch Wizard
MP while the Wizard MP is operating, the mouse will not work correctly when you
plug it back in. To avoid having to reboot the entire system in this situation, the
Wizard MP has an automatic mouse-recovery system.
With the PS/2 mouse disconnected, change the channel using the Wizard MP’s
front-panel pushbutton or the keyboard hotkeys. The ServSwitch Wizard MP
detects that the mouse has been disconnected and triggers the automatic recovery
system. Plug in the PS/2 mouse and the ServSwitch Wizard MP will re-initialize it.
Alternatively, you can reset the keyboard and mouse by holding the Wizard MP’s
front-panel pushbutton down for five seconds to enter configuration mode, then
releasing the button, then pressing the button again while the display shows “C”.
When you do, the Wizard MP will perform a complete power-off reset of the
connected keyboard and mouse. This function only resets the shared keyboard and
mouse that are plugged into the control port; it does not affect the status of any of
the other ports on the Wizard MP or of the CPU connections.
5.9 Hot-Plugging Devices Into the ServSwitch Wizard MP and Re-Enabling
Disconnected CPU PS/2 Mouse Ports
We suggest that you turn off the computers that will be connected to the
ServSwitch Wizard MP before you install a Wizard MP system. However, even if this
is not possible, most systems can be “hot-plugged” (connected to the Wizard MP
while they are powered and operating); the PS/2 mouse-port malfunctions this
usually causes can often be overcome by using the ServSwitch Wizard MP’s mouse-
restoration functions. (The keyboard connection will normally restore itself
automatically.)
Let’s take this from the top: On many computer CPUs, mouse movement will be
lost if the PS/2 mouse is unplugged and plugged back in while the CPU is
running. Mouse movement can then only be restored by rebooting the CPU. This
is because the mouse drivers only set up and enable the mouse when the CPU is
initially booted.
If you have powered down your ServSwitch Wizard MP, or if you are attempting
to hot-plug a system into it, you might be able to restore lost mouse movement
using the ServSwitch Wizard MP’s mouse-restoration functions.
