Avaya S8400 User Manual

on page 16 describes the connections for the 

media server cable adapter.

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.
