FCC Statement
This device generates and uses radio frequency and may cause interference to radio and television reception if not
installed and used properly. This has been tested and found to comply with the limits of a Class B computing device in
accordance with the specifications in Part 15 of the FCC Rules. These specifications are designed to provide reasonable
protection against such interference in a residential installation. However, there is no guarantee that interference will not
occur in a particular installation. If this device does cause harmful interference to radio or television reception, which can
be determined by plugging the device in and out, the user can try to correct the interference by one or more of the
following measures:
Reorient or relocate the receiving antenna.
Increase the separation between the device and receiver.
Connect the computer into an outlet on a circuit different from that to which the receiver is connected.
Consult the dealer or an experienced radio/TV technician for help.
Rack-mount Safety Instructions
Elevated Operating Ambient –
If installed in a closed or multi-unit rack assembly, the operating ambient temperature of the rack environment may
be greater than room ambient. Therefore, consideration should be given to installing the equipment in an
environment compatible with the maximum ambient temperature (Tma) specified by the manufacturer.
Reduced Air Flow –
Installation of the equipment in a rack should be such that the amount of air flow required for safe operation of the
equipment is not compromised.
Mechanical Loading –
Mounting of the equipment in the rack should be such that a hazardous condition is not achieved due to uneven
mechanical loading.
Circuit Overloading –
Consideration should be given to the connection of the equipment to the supply circuit and the effect that
overloading of the circuits might have on overcurrent protection and supply wiring. Appropriate consideration of
equipment nameplate ratings should be used when addressing this concern.
Reliable Earthing –
Reliable earthing of rack-mounted equipment should be maintained. Particular attention should be given to supply
connections other than direct connections to the branch circuit (e.g. use of power strips).

4.3. Install a KVM Switch (Single-Tier Installation)
4.3.1. Installation Guidelines
All computers and devices must be turned OFF prior to installation.
Disconnect power cords from the computers implemented with the Keyboard
Power On function prior to installation, or the KVM switch may not work properly.
Computers running Windows 98 must be connected to a KVM switch via PS/2
ports because Windows 98 does not support initial installation through the USB
HID driver.
Old computers may require USB setting adjustment in the BIOS to enable the
USB interface.
There is no guarantee that the EZswitch KVM switch can fully support a USB
keyboard via a USB hub.
4.3.2. Console Connection
Connect a keyboard, mouse and monitor to the console ports on the real panel
of EZswitch (see Figure 5).

5
Figure 5: Console connection
4.3.3. System Connection
You need a custom combo cable to connect a computer to the EZswitch KVM
switch.
Note: If needed, contact your dealer or Raritan to purchase the custom KVM cables.
Figure 6: Custom KVM cable

6
There are three different ways to connect 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.
Figure 7: USB, PS/2 and VGA connections
B. Plug only the combo cable’s PS/2 keyboard, PS/2 mouse and VGA
connectors into a computer (see Figure 8).
Figure 8: PS/2 and VGA connections

7
C. Plug only the combo cable’s USB and VGA connectors into a computer
(see Figure 9).
Figure 9: USB and VGA connections
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 required 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 switches 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 (connected to the Master KVM switch), if
any
3. Third-tier Slave KVM switches (connected to the second-tier Slave KVM
switches), if any
4. All computers connected to KVM switches
I. Connect other devices such as a montior 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 support hot plug and hot swap functions.

4.5. Firmware Upgrade Port
The min-USB female connector on the rear of the EZswitch KVM switch is used for
firmware upgrade. Contact your dealer or Raritan when you need to update the
firmware.
4.6. Rack-Mount the KVM Switch
Figure 11: Rack mounting
This section describes how to attach mounting brackets to the KVM switch for
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.
5. Operation
You can control computers connected to the EZswitch KVM switch by using the
push buttons, hot keys or OSD interface.
