Relocation Of Port Circuit Packs - Avaya DEFINITY Server R Manual

Contact Network Technicians
The technician for each public and private network accessed by the switch must
be contacted before the upgrade begins. Otherwise, if these technicians are not
aware of the service interruption caused by the upgrade, it is possible that
network-access trunk facilities will be busied out at the far end.

Relocation of Port Circuit Packs

With the possible exception of a port circuit pack in slot 01 of control cabinet A that
must be moved for a TN570 Expansion Interface, an upgrade does not cause port
circuit packs from the Release 5/6si control cabinet to be moved and manually
retranslated. This is because a Release 5/6si PPN is always upgraded to an EPN.
So, during the PPN upgrade to the new EPN, an expansion control cabinet (with
14 to 16 available port slots) always replaces the Release 5/6si control cabinet
(with 10 available port slots), providing a net gain of from 4 to 6 port slots.
If a port circuit pack does reside in slot 01 of control cabinet A, the STS software
upgrade retranslates this circuit pack to reside in an empty port slot in the new
expansion control cabinet.
For an upgrade to a critical reliability, if a port circuit pack resides in slot 02 of port
cabinet B, the STS software upgrade retranslates this circuit pack to occupy
another empty port slot in the new expansion control cabinet.
To provide maximum holdover for a TN750/B Announcement circuit pack that did
not reside in the control carrier, the STS software upgrade relocates this circuit
pack to occupy another empty port slot in the new expansion control cabinet.
To ensure reliable DS1 timing, the STS software upgrade relocates the DS1 circuit
packs serving as the primary and secondary timing sources to occupy 2 empty
port slots in the new PPN.
When connecting adjuncts to an upgraded system, STS locates any new interface
circuit packs (including TN577 Packet Gateway, TN553 Packet Data Line, and
TN726B Data Line) in the first available slots of the first PPN port carrier.
NOTE:
To find out where STS relocated these circuit packs, refer to the annotated
"list configuration all" that STS provides with the new Avaya MultiVantage
Software on removable media.
