4.4. Cascade Chaining
A cascade configuration expands the system’s capabilities and allows you to
select computers connected to the Master or Slave switch. The KVM switch
supports cascades of up to 3 levels, letting you control up to 64/256/4096 PCs
from a single console. Cascaded units do not require any special configuration.
Once connected, the KVM switches will automatically configure themselves
appropriately as Master or Slave.
To install a cascade chain, please follow the instructions below:
A. Please turn off all the computers and devices before you start installing the
KVM switches.
B. Use the custom combo cable set (See Figure 6)to connect one or more
Slave KVM switches to any PC port of the Master KVM switch. Individual
KVMs must be connected through a PS/2 & USB connection.
( Please refer to Figure 7 )
C. Plug in the power adapter of the first level Master KVM switch and
connect the Master KVM switch to the computers.
D. Plug in the power adapter for each level Slave KVM switch and connect the
slave KVM switch(es) to the computers.

12
E. The power-on sequence should be as follows:
1. Master KVM switch
2. Second level Slave KVM switch (connected to the Master KVM switch),
if any.
3. Third level Slave KVM Switch (connected to the second level Slave
KVM switch), if any.
4. All computers connecting to the Master/Slave KVM switches.
F. When all the KVM switches are powered on, turn on the computers.
Initial Plug-in Process:
Please plug in the Master KVM switch first before turning on any
other devices such as montiors or computers.
Hot Plug and Hot Swap:
This KVM switch supports hot plugging and hot swapping.
