Installation of Computer Modules
PS/2 computer modules
If a computer is already running and its PS/2 interface has already been initialized, it is not necessary to turn
off the computer. Simply hot-plug the PS/2 computer module to the computer. Always connect the PS/2
mouse port first to allow the correct initialization sequence! If the PS/2 ports of the computer haven’t been
initialized during boot up it may however be necessary to turn off the computer before connecting the PS/2
computer module so the OS can initialize the PS/2 ports during boot up.
USB computer modules
The USB and VGA interface is hot pluggable on most OS and computer systems. Therefore you may
connect and disconnect USB computer modules at any time if supported by the computer’s OS.
Connect the computer modules to the KVM Switch using UTP Cat.5e/6 cables of appropriate length. In most
cases standard UTP patch cable Cat.5e or 6 can be used without any problems. For best video results at
very large distances and high resolutions UTP Cat.6 solid core cable may be used to improve video quality
and distance. Shielded FTP/STP/PIMF is not recommended.
After all the computers are connected and powered up you can access them from the KVM Switch CAT-16.
