8/64/512 PCs ( for 8-port only ) and 16/256/4096 PCs ( for 16-port only ), from a
single console; cascaded chaining units do not need special configuration.
Cascaded configuration expands system ability and allows you to select computers
connected to the Master or Slave. After connected, KVM Switches automatically
configure Master and Slave.
Note: IP-KVM should be the master KVM Switches, and the second & third
layers could use Standard KVM Switches without Over-IP function
( Combo KVM Switches connected to 2nd & 3rd layers ).
To Install cascade chain, please follow the instruction below:
A. Please turn off computers and devices when you start to install KVM Switch.
B. Uses the custom combo 4-in-1 cable set (See Figure 6)to connect one or
more Slave KVM Switches to any PC port of Master KVM Switch. The
connection between KVM to KVM must be connected through PS/2
connection. ( Please refer to Figure 7 & Figure 8 ).
C. You can do console Master KVM Switch via either USB and/or PS/2
keyboard and mouse at will.
D. Plug in the power adapter of the first level Master KVM Switch and connect
Master KVM switch to computers.
E. Next, plug in power adapter for each level Slave KVM Switch and connect
Slave KVM switch to computers .
F. The power on sequence should be:
1. Master KVM Switch
2. Second level Slave KVM Switch (connecting to Master KVM Switch) if any.
3. Third level Slave KVM Switch (connecting to second level Slave KVM
Switch) if any.
4. All computers connecting to Master/Slave KVM Switch.

-12-
G. After all KVM Switches are powerd by power adaptor, trun on the computers.
Initial Plug-in Process:
Please plug in the Master KVM Switch first before turning on any other
devices like montior or computers.
Hot plug and Hot Swap:
Combo 8-port & 16-port KVM switch support Hot plug and Hot swap
function.
