INSTALLATION
Installation consists of inspecting the equipment for damages,
following proper safety precautions, attaching the mounting
ears in the correct position for the desired mounting type,
mounting the jack panel in a rack or on a wall, and connecting
cables per company practice.
‐ INSPECTION NOTE ‐
Visually inspect the unit for damage prior to installation. If the
equipment was damaged in transit, immediately report the damage
to the transportation company and to Westell (see Part 6).
‐ PRECAUTIONARY STATEMENT ‐
Never install telephone wiring during a lightning storm.
Never install telephone jacks in wet locations unless the jack is
specifically designed for wet locations.
Never touch uninsulated telephone wires or terminals unless the
telephone line has been disconnected at the network interface.
Use caution when installing or modifying telephone lines.
2.1
Jack Panel Installation
There are two mounting types; one is rack mounting and the
other is wall mounting. See Table 1 for a step‐by‐step installa
tion procedure and refer to Figure 3 if needed.
2.1.1
Rack Mounting
The jack panel can be mounted in both 19” and 23” relay racks.
The panel ships with the ears attached in the 23” rack mount
position. The mounting ears may be detached from the panel,
reversed, and re‐attached for 19” rack mounting.
2.1.2
Wall Mounting
The jack panel may be mounted on a wall. It is recommended
that local company practices be followed for wall mounting and
that ½‐inch or ¾‐inch plywood be mounted to the wall prior to
installing the panel. For best cable access and hand mobility, at
tach the 64‐pin cables and secure cable ties prior to mounting
