There are three different ways to connec t a computer. See the instructions 
below: 
  A.  Plug the combo cable’s USB,  PS/2 keyboard, PS/2 mouse and VGA 
connectors into a computer (see  Figure 7). This method is highly 
recommended for computer connection.

4.4.  Cascade KVM Switches (Multi-Tier Installation) 
You can cascade either the 8-port or the 16- port EZswitch products up to 3 tiers, 
expanding the number of computers to  64, 256 or 4096 computers. No special 
configuration is requi red for the cascade. 
After completing the installation, the system  automatically configures the Master and 
Slave KVM switches. The Master KVM switch  is the first-tier KVM switch and Slave 
KVM switches are second-tier or third- tier KVM switches. You can select the 
computers connected to the Master or  Slave KVM switches at any time. 
To cascade KVM switches, follow these instructions:  A.  Turn OFF all computers and devices. 
B.  Connect one or more Slave KVM switc hes to the channel ports on the Master 
KVM switch using the custom combo cables (see 
Figure 6). The connection 
between KVM switches must be done via the PS/2 interface (see 
Figure 7 & 
Figure 8 
).  
C.  Connect a USB or PS/2 keyboard and mouse to the console ports on the Master 
KVM switch. 
D.  Connect a power adaptor to  the Master KVM switch. 
E.  Connect computers to  available channel ports on the Master KVM switch. 
F.  Connect a power adaptor to each Slave KVM switch. 
G.  Connect computers to  available channel ports on the Slave KVM switch. 
H.  Turn on each device in the folloiwng sequence: 
1.  Master KVM switch 
  
						

							  8 
2.  Second-tier Slave KVM switches (connec ted to the Master KVM switch), if 
any 
3.  Third-tier Slave KVM switches (c onnected to the second-tier Slave KVM 
switches), if any 
4.  All computers connected to KVM switches 
I.  Connect other devices such as a montio r or new computers to the Master KVM 
switch before turning on the additional devices. 
J.  Now you can hot swap or hot plug any devices into any KVM switches. Both of  8-port and 16-port KVM switches suppor t hot plug and hot swap functions.

rack-mounting it on a standard 19-inch rack. 
A.  Screw the mounting brackets to the sides of the KVM switch (see  Figure 11). 
B.  Mount the KVM switch on a rack.
