2.11 Hot plugging the CPU Switch Smart DVI 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 CPU
Switch Smart DVI before installation. However, if this is not possible then most
systems can be hot plugged by using the CPU Switch Smart DVI’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 CPU Switch Smart DVI 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 CPU Switch Smart DVI's mouse restoration functions.
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 CPU Switch Smart DVI. 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.
