DEFINITY Server SI in an MCC
When you migrate an existing DEFINITY Server SI in a multicarrier cabinet (MCC), you use one
TN2312BP IPSI circuit pack to control from one to three port networks (PNs). Avaya
recommends that you install the IPSI in the A carrier in the existing processor port network
(PPN) instead of in one of the expansion port networks (EPNs). But before you install the IPSI,
you must convert the PPN to a PN. This process requires that you:
● Replace the processor control carrier with an expansion control carrier.
● Remove all the control circuit packs.
This migration affects service because you must be turn off the carrier. Before you turn off the
cabinet, you must perform some premigration administration.
DEFINITY Server SI in an SCC
When you migrate an existing DEFINITY Server SI in a single carrier cabinet (SCC), you use
one TN2312BP IPSI circuit pack to control from one to three PNs. Avaya recommends that you
install the IPSI in the cabinet in the A position in the existing PPN instead of in one of the EPNs.
But before installing the IPSI, you must convert the PPN to a PN. This process requires that
you:
● Replace the processor control cabinet with an expansion control cabinet.
● Remove all the control circuit packs.
This migration affects service because you must turn off the PPN stack to replace the cabinet.
Before turning off the cabinets, you must perform some premigration administration.
DEFINITY Server CSI or DEFINITY ONE/S8100 in a CMC
When you migrate an existing DEFINITY Server CSI or DEFINITY ONE in a compact modular
cabinet (CMC), you use one TN2312BP IPSI circuit pack to control the PN. If a CSI, you replace
the TN2182 Tone Clock circuit pack with the IPSI which you install in the A position of the
cabinet. You also must remove the processor circuit pack. If a DEFINITY ONE, you replace the
processor circuit pack with the IPSI.
This migration affects service because you must turn off the CMCs to replace the processor and
the tone clock circuit packs. Before you turn off the cabinets, you must perform some
premigration administration.
