16 Installing and Configuring the Avaya S8400 Media Server February 2006
Table 3: Media server cable adapter port labeling on page 16 describes the connections for the
media server cable adapter.
Ethernet connectivity with the TN8412AP circuit pack
The S8400 Media Server supports connectivity with the TN8412AP (SIPI) circuit pack through a
10/100 BaseT Ethernet twisted pair on the IPSI-2 cable adapter. This interface is for control only
- no bearer traffic is carried over this connection. This Ethernet is connected to the
Communication Manager Processor complex. The IPSI-2 cable adapter is mounted on the rear
of the TN8412AP SIPI circuit pack.
The physical connection between the TN8412AP and the TN8400 circuit packs is made by
either:
1. Using a 10/100 Base T Ethernet crossover cable that directly interconnects the
appropriate backplane pins of the two circuit packs. This cable plugs into the TN8400AP
cable adapter RJ45 ETH-A port and the TN8412AP IPSI-2 adapter RJ45 control port.
2. Connection to the customer LAN.
