Foreign Exchange Station (Fxs) Interface Modules - Avaya Secure Router 4134 Hardware Installation

Before working on this equipment, be aware of good safety practices and the hazards
involved with electrical circuits. Use only power cords that have a grounding path. Ensure
the switch is properly grounded before powering on the unit.
Warning:
Risk of eye injury by laser
Fiber optic equipment can emit laser or infrared light that can injure your eyes. Never look
into an optical fiber or connector port. Always assume that fiber optic cables are connected
to a light source.
Caution:
If you do not install interface modules in slots, keep the metal cover plates in place over the
slots. Removing the cover plates impedes airflow and proper cooling of the unit.

Foreign Exchange Station (FXS) Interface Modules

Important:
Ensure you use standard straight-through RJ11 modular telephone cables with FXS
interface modules. TIP must connect to TIP and RING must connect to RING. FXS ground
start does not work if polarity is reversed.
Important:
Avaya does not support FXS port connections leaving the building. Use FXS connections
for intra-building purposes only.
Warning:
The 2- and 4-port FXS interface modules have a ring signal generator that is a source of
hazardous voltage. Do not touch the RJ11 port conductors, the conductors of a cable (that
is, the exposed metal ends of a cable connector) connected to the RJ11 port, or the circuit
board when the ringer is active (an incoming call activates the ringer).
