(RJ-45)

This connector provides a 10 Mbit/s Ethernet 
connection between the 201i server and the 
Meridian 1 switch or Succession 1000 system. This 
connection allows the exchange of call control 
information between the server and the Meridian 1 
switch or Succession 1000 system.

LAN-based server administration

If you need Ethernet 100Base-T operation at 
100 Mbit/s on large Meridian 1 systems (such as 
Option 51), you must install the NTRH3501 
backplane (tip and ring) cable. For more information, 
see Chapter 4, “Installing the 201i server in a large 
Meridian 1 system.”
