the assembly, making all grounding and power connections, per
forming the installer connections for network and customer
wiring and installing the plug‐in module(s) into the assembly.

‐ INSPECTION NOTE ‐

Visually inspect the equipment for signs of damage at the time of delivery.
If the equipment has been damaged in transit, immediately report the ex
tent of the damage to the transportation company and to Westell (see Part
5 for telephone number).

CAUTION ‐ STATIC‐SENSITIVE

This product and the plug‐in product installed inside the assembly
may contain static‐sensitive components! Proper electrostatic
discharge procedures must be followed to maintain personal and
equipment safety. Do not store units near magnetic, electromagnetic
or electrostatic fields.

‐ 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/terminals unless the
telephone line is disconnected at the network interface.

Use caution when installing or modifying telephone lines.

3.1

Selecting the Mounting Location

The 528‐02I2 should be wall‐mounted in accordance with local
practices. The installation site should provide adequate lighting
and equipment access. The distance from the cable entry point
should be consistent with local installation practices. Allow ade
quate clearance to accommodate the motion required by the
key‐hole slots (¼‐inch) when locating the assembly for installa
tion. Also ensure that adequate clearance is available for
opening the cover/door and for inserting and removing the mod
ule(s), which slide(s) into place inside the cover.

3.2

Gathering the Mounting Tools and Hardware

The tools required to mount the assembly include:

Flat‐blade screw driver (to adjust the terminal block
screws and to adjust the mounting screws and ground lug)

Wire strippers (for signal, power, and ground wires)

Drill and drill bits (to drill holes for mounting screws/bolts)

Mounting hardware (four screws or bolts)

Wirewrap tool (optional, for L4‐9 option only)

‐ NOTE ‐

The 528‐02I2 optionally may be set on a table, shelf, or desk.
For desktop installations, four self‐adhesive rubber feet are provided and
are to be installed on the bottom of the assembly to help prevent marring
the desktop surface.

3.3

Mounting the Assembly to a Wall

Loosen the top‐cover screw and open the cover.

Using the mounting screw keyholes in the assembly's base
plate as a template, carefully lift the assembly to the de
sired mounting position on the wall and mark the four
mounting screw keyhole locations for the assembly (see
Figure 3). The keyholes allow the assembly to be mounted
so the Customer Interface connections may face either
left, right, or down. Set aside the assembly.

Drill the four holes in the mounting surface.

Insert and drive the mounting screws into their holes in the
wall until they are just shy of the wall (until approximately
¼‐inch protrudes/remains).

Lift the assembly, align the keyholes with the protruding
screws in the wall, and hang the assembly from the screws.

Finish driving all screws until snug. Do not over‐tighten the
screws.

‐ CAUTION ‐

Never apply power until all installer connections are complete.

‐ GROUNDING NOTE ‐

Always follow the National Electrical Code (NEC) rules, local safety pre
cautions, and standard operating procedures for grounding the equipment
when installing, upgrading, repairing or maintaining equipment. Any in
structions or information contained herein is subordinate to local codes,
operating procedures or practices.

3.4

Connecting Telco/Network Interface Cables

Telco or network interface connections to the assembly are
made to one or both screw terminal blocks, TB1 and TB3, using
shielded twisted pair cable (22‐24 AWG minimum) of a length
consistent with local installation practices. If only one module
is used in the unit, insert it into the top (upper) slot or position
and use TB1 for the network connections. Telco/network con
nection pin numbers are listed in Table 2.
