Add a Switch Node Carrier (High or Critical Reliability)
To upgrade to a high or critic al reliability R8r, a second switc h node carrier is
added either to an emp ty “E” carrier p osition of an existing multicarrier p ort
network or to the “D” carrier p osition (as the duplic ate switch node carrier) of an
existing multicarrier cab inet.
NOTE:
To avoid moving a port carrier, the p referred practice is to place the new
switch node carrier in an empty carrier position.
