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 in the G2 module control carrier 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
DEFINITY Enterprise Communications Server Release 8 Administrator’s Guide
,
for instructions on performing the retranslations.
