Upgrading a Multicarrier G2 Universal Module to Avaya
DEFINITY Server R EPN running Avaya MultiVantage
Software
Close Upgraded EPN Cabinet and Reconnect
Cables
1. At the upgraded EPN, set the main circuit breaker to OFF.
2. Temporarily disconnect the lightwave transceivers and fiber optic cables
from the appropriate carriers.
3. Replace the back doors or back panels previously removed.
4. At the EPN cabinet, reconnect the lightwave transceivers, fiber optic
cables, and the connector cables associated with the carrier being
replaced.
5. Install the front door on the EPN cabinet.
Power Up the EPN Cabinets
1. At each EPN power distribution unit, set the main circuit breaker to ON.
After about 40 seconds, EPN power and PPN/EPN communications return.
2. After power returns to each EPN and all trouble is cleared, verify that the
EMERGENCY TRANSFER CONTROL switch is set to AUTO. This
restores the system to the normal mode.
Retranslate Port Circuits
If port circuit packs were relocated in order to put:
A critical port circuit pack, requiring longer nominal battery holdover (such
as a DS1 or an Announcement circuit pack), in a port slot
A TN736, TN752, or TN755 power supply in port slots "18" and "19"
A TN776 or TN570 Expansion Interface in port slot "1"
A TN776 or TN570 in port slot "2" (for a second directly connected EPN)
of the new expansion control carrier, verify that they were retranslated during the
off-site software upgrade. If not, they must be retranslated now. Refer to
Administrator's Guide for Avaya MultiVantage Software.

NOTE:
Powering down an EPN without powering down the PPN will set off
alarms. However, these alarms should clear after power is restored to
each EPN.
