CATEGORY 5 PRIMARY AND SECONDARY SURGE PROTECTORS

3.2 Installation Procedures

In order to operate as designed, the Surge Protectors must be connected
correctly to your Category 5 network. Please read all the instructions below
and follow them carefully.
3.2.1 C
ONNECTING THE
1. Turn off or power down the the device you want to connect the Surge
Protector to. Disconnect the specific twisted-pair line you want to
protect from the device port it is currently attached to.
2. Install the Surge Protector between the incoming twisted-pair line and
the port that the line was connected to (see Figure 3-3 below). You will
have to run a straight-through-pinned Category 5 patch cable with
modular RJ-45 connectors from the Surge Protector to the port; we
suggest that you use the cable supplied with the Surge Protector. It
doesn't matter which end of the Surge Protector is attached to the
twisted-pair line and which end is attached to the patch cable.

3. Locate a metal chassis ground on the device. This is often a hex screw
on a D-shell or AUI connector. Sometimes a metal rear panel is
attached to the rest of the device with screws, one of which can be used
for chassis grounding. If you cannot locate a chassis-ground
connection point on your equipment, contact your supplier's technical
support to discuss an alternative grounding solution.
