Before you install 

The default setting of the 4/8/16-port 19” Rackmount PS/2 KVM Switch 

is appropriate for most systems.  In fact, you do not have to make any 

configuration before installation. It’s an out-of-the-box installation: Just 

connect and set up the cable connections for the KVM switch and your 

computers, boot them up in correct sequence and you can start to 

operate immediately! 

For a quick start on installation and operation, please follow the 

instructions below. 

Out-of-the-box Installation 

Take the KVM Switch out of the box and begin installation... 

 If you are using only window PCs:  for the first-time 

installation, you don’t even need to power down all the 

computers that are going to be connected to the KVM Switch….. 

The hot-pluggability of this KVM Switch allows “hot-plugging” of the 

KVM cables while the computer is powered on, and your mouse will stay 

alive throughout. It is especially convenient when you have to change or 

rearrange the KVM cablings of your computers while still want to keep the 

computers working.  

If you are using any Linux PCs: you might possibly experience a 

lock on mouse if hot-plugging it to the KVM switch (since Linux is not a 

PnP OS somehow)… If your mouse gets locked, you can try to use the 

mouse reset hotkeys (see the Quick Reference Sheet) to bring it back 

to normal. Another alternative is to turn the Linux PC off before 

connecting it to KVM Switch. 

Step 1. Connect the shared mouse, keyboard and monitor to the console 

port connectors on the backpanel of your KVM Switch. 

 Note that since the KVM Switch is powered through the PS/2 

interface, it is powered on immediately when connected to the PS/2 

keyboard/mouse port of your PC (nonetheless even when the PC being in 

powered off state, the PS/2 interface is still live with electricity). 

Step 2. Just connect your computers (no matter they are powered on or 

off!) to the PC ports at the backpanel of the KVM Switch using 

the KVM combo cables. You can use individual standard 

keyboard, mouse and video cables for connection, although the 

3-in-1 combo cable is highly recommended for your 

convenience. 

Step 3. If your computer is still not powered up, then power them up.  

Once the computers are powered up  (or they are already 

powered on before connecting to KVM Switch), you can 

manage all of them through the KVM Switch.  

If you experience mouse lock on any of your computer,  You can use 

the mouse reset hotkey sequence to regain the mouse control (see the 

Quick Reference Sheet). 

Easy Operation 

There are two methods to select a specific computer, using a front-panel 

push button or a hotkey sequence. 

Front-panel push buttons 

The front-panel buttons let you have direct control over KVM switch 

operation and channel switching. Simply press a button to switch to its 

corresponding channel. 

See Quick Reference Sheet

Keyboard hotkeys 

A keyboard hotkey sequence consists of at least three specific keystrokes:

See Quick Reference Sheet

Hotkey sequence = ScrLk + ScrLk + Command key(s)

The two consecutive ScrLk keystrokes should be pressed within 2 

seconds and the following command key(s) should also be pressed within 

2 seconds in likewise manner. Otherwise, the hotkey sequence will not be 

validated. 

For detailed Hotkey sequences and their corresponding functional 

commands.
