2.10 Other useful installation information
PC boot up sequence - When your PCs are powered on they communicate with
any attached keyboards and mice and setup parameters required by the particular
operating system. It is necessary for the X-KVM to be attached and powered on
during this sequence so that it can give the required responses and keep track of all
the modes and settings requested by each of the connected PCs.
Mouse characteristics - do not unplug a PS/2 mouse connection from a PC whilst
the PC is on. Due to the design of PS/2 mice communications the mouse function on
the PC will be lost and you will have to re-boot the PC to regain normal operation.
Unplugging the mouse from the X-KVM will also cause it to stop operating when it is
plugged back in. RS232 mice can usually be unplugged and plugged back in
provided that a mouse was connected when the operating system initially booted.
Keyboard and mouse mode switching - The X-KVM keeps a log of the keyboard
and mouse mode and resolution settings requested by the connected PC. These
settings are automatically communicated to the keyboard and mouse as required to
ensure maximum software compatibility. The keyboard num, caps and scroll lock
states are an obvious example of this process.
2.11 Hot plugging the X-KVM into running systems and re-enabling
disconnected CPU PS/2 mouse connections
It is adviseable to switch off the systems that are going to be connected to the X-
KVM before installation. However if this is not possible then most systems can be
hot plugged by using the X-KVM’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.
