Add a Switch Node Carrier
You can add a switch node carrier to a standard reliability DEFINITY ECS with
Center Stage Switch (CSS) or add a second switch node carrier to a high or
critical reliability DEFINITY ECS. The new carrier is added either to an empty E
carrier position of an existing multicarrier port network or to the D carrier position
(as the duplicate switch node carrier) of an existing multicarrier cabinet.
NOTE:
To avoid moving a port carrier, the preferred practice is to place the new
switch node carrier in an empty carrier position.
Service Interruption
Because adding a first or second switch node carrier requires a service
interruption, notify the customer in advance as to when the addition will be carried
out.
Verify System Status
1. Before proceeding, exam the system for alarms, and correct every
problem. The system must be alarm-free.
