Add a Switch Node Carrier (High or
Critical Reliability)
To upgrade to a high or critical reliability R8r, a second switch node 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
1. Since the addition of the 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, the system should be examined for alarms, and every
problem should be corrected. The system must be alarm-free.
