CHAPTER 5: Operation
5.7 Re-Enabling a Disconnected PS/2 Mouse
If you accidentally disconnect the shared PS/2 mouse from the ServSwitch Wizard
while the Wizard 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
has an automatic mouse-recovery system.
With the PS/2 mouse disconnected, change the channel using the Wizard’s
front-panel pushbutton or the keyboard hotkeys. The ServSwitch Wizard detects
that the mouse has been disconnected and triggers the automatic recovery system.
Plug in the PS/2 mouse and the ServSwitch Wizard will re-initialize it.
Alternatively, you can reset the keyboard and mouse by holding the Wizard’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 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 or of the CPU connections.
5.8 Hot-Plugging Devices Into the ServSwitch Wizard and Re-Enabling
Disconnected CPU PS/2 Mouse Ports
It is advisable to switch off the computer systems that are going to be connected to
the ServSwitch Wizard before installation. However, even if this is not possible,
most systems can be “hot-plugged” (connected to the Wizard while they are
powered and operating); the PS/2 mouse-port malfunctions this usually causes can
often be overcome by using the ServSwitch Wizard’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, or if you are attempting to
hot-plug a system into it, you may be able to restore lost mouse movement using
the ServSwitch Wizard’s mouse-restoration functions.
Important:
Mouse-restoration functions should be used with caution, because
unpredictable results may occur if the wrong mouse type is selected. If in doubt,
restore the mouse by rebooting the CPU normally.
