Migrating Mcc Or Scc To G650 Media Gateways; Powering Down The Cabinets - Avaya S8500 Manual

Migrating MCC or SCC to G650 Media
Gateways
All reusable circuit packs and their associated cables must be moved from the SCCs and the MCC
carriers to the G650 Media Gateways. To do this, follow this general procedure:
•
Gracefully shut down the MCC1 or SCC1 cabinets starting with the EPNs.
•
Pull the reusable circuit packs from the cabinets or carriers.
•
Disconnect any adapters and associated cable(s) from the rear connector panels that can be
reused.
•
Install the adapters and associated cable(s) to the correct slots on the rear connector panels of the
G650 Media Gateways.
•
Install the circuit packs in the correct slots in the G650 Media Gateway.
•
Connect the port I/O cables to the Main Distribution Frame (MDF) and the Public Switched
Telephone Network (PSTN).
•
Connect the IPSIs to the media server.

Powering down the cabinets

You must gracefully shut down the MCCs or SCCs before pulling the circuit packs. Start with the EPNs;
shut down the PPN last.
1
Connect a 10 AWG (#25) (2.6 mm
power-failure transfer panel.
2
Route the opposite end of the wire to an approved ground and connect.
3
At the port network's power distribution unit, set the main circuit breaker to OFF.

CAUTION:
This process requires a service interruption from when the DEFINITY ECS is powered
down to when the circuit packs are relocated and the telephones and other stations and
trunks are connected to the new Avaya G650 Media Gateways.
CAUTION:
Make sure you have done the premigration administration. See
administration (R, SI, CSI)
NOTE:
If the system is equipped with Power Failure Transfer (PFT) units using ground start
trunks, you must install a temporary ground wire to the PFT units to allow them to operate
properly when the cabinet is powered down. The AUX cable, that normally supplies the
ground, will be disconnected.
