Following Safety Precautions
Before installing the NIU, observe the following safety notes.
CAUTION
Risk of electric shock. Voltages up to 140 VDC (with reference to
ground) may be present on telecommunications circuits.
CAUTION - STATIC-SENSITIVE
This product contains static-sensitive components! Follow
proper electrostatic discharge procedures to maintain
personal and equipment safety. Do not store units near
magnetic, electromagnetic or electrostatic fields. Always
store or ship units in the original static-protective packaging
from Westell. Use anti-static mats when working on units.
- 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 phone line has been disconnected at the network interface.
- Use caution when installing or modifying telephone lines.
- This equipment is intended to be used behind devices that
provide primary lightning protection.
- This installation should conform to Local Codes and NEC
requirements.
- This equipment is to be installed in a restricted access location.
- CAUTION -
Never apply power until all installer connections are made.

Mounting the Module
The 3116-10 is a 200 MECHANICS
-type plug-in module that
mounts in a 200- or 400-mechanics-type mounting assembly (or
equivalent mounting which matches the pin-out plan of the
module). Before installing the module, set any options in the de-
sired position(s). Align the module with the mounting or
assembly card guides above and below the unit and insert as far
as it will go into the slot connector.
- CAUTION -
Use care when installing and removing modules -
do not force
into place
. If a module resists insertion, remove it and check
for obstructions in/near the connectors and mounting slots,
then carefully re-align and gently re-insert the module.

Making Installer Connections
No installer connections are required other than inserting the
module into the card-edge connector in the shelf or assembly.
The unit makes electrical connections to external equipment
when installed and properly seated in the 56-pin card-edge con-
