Migrating from a DEFINITY Server SI in an SCC to an S8700-Series Media Server with Fiber-PNC
In duplex configurations, each media server is connected to the Ethernet switch or switches that
comprise control network A (CNA) (green cable).
In high-reliability and critical-reliability configurations, each media server is connected to the
Ethernet switch or switches that comprise control network B (CNB) (red cable).
Upgrading the hardware in each port network
In IPSI-controlled PNs, you must replace the existing tone clock and the maintenance circuit
packs with a TN2312BP IPSI circuit pack and TN775D or later Maintenance circuit pack,
respectively. You also must replace the TN570 (R) Expansion Interface circuit packs with
TN570B, vintage 7, or later circuit packs.

and the cabinet number on the IPSI circuit pack. However, you must complete
certain sequences before to a predetermined timeout interval. If you do not set
the switch ID and the cabinet number when you first install the circuit pack, it can
be done later but it requires that the circuit pack be reseated. This might result in
an additional service interruption in a duplex reliability configurations.
Determining IPSI placement in port networks
Use this information to determine in which PNs you must install the IPSI circuit packs. Not all
PNs require IPSI circuit packs. PNs that do not contain an IPSI have an Expansion Interface
(EI) circuit pack that controls the PN. These EI-controlled PNs are assigned automatically to an
IPSI when the system is initialized. The system automatically balances the EI-controlled PNs
among the available IPSIs.
