Foreign Exchange Station (Fxs) Interface Modules; Foreign Exchange Office (Fxo) Interface Modules - Avaya 2330 Manual Del Usario

• Do not leave interface module or power supply module slots empty. You must fill all slots
with modules or slot covers to maintain safety compliance, proper cooling, and
electromagnetic interference (EMI) containment in the shelf.
• Ensure that your environment meets the requirements for temperature, humidity, and
cleanliness.
• Do not overtighten thumb screws or lug nuts. Tighten screws and nuts until they are snug,
plus a quarter turn. If you use a power tool to tighten screws, use a low torque setting of
2 to 3 in–lb (0.226 to 0.339 N-m).
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.
Voltage:
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).

Foreign Exchange Office (FXO) Interface Modules

Important:
Ensure you use standard straight-through RJ11 modular telephone cables with FXO
interface modules. TIP must connect to TIP and RING must connect to RING.
Voltage:
The 2-port and 4-port FXO interface modules can receive a ring signal that is a source of
hazardous voltage. Do not touch the RJ11 port conductors or the conductors of a cable (the
exposed metal ends of a cable connector) connected to the RJ11 port.
