Upgrading to the Control Board-Routing Engine REMX2K-X8-64G in a
Redundant Host Subsystem
A redundant host subsystem consists of a master Routing Engine-Control Board (CB-RE) (RE0) and a backup
CB-RE (RE1). To upgrade the host subsystem to use the REMX2K-X8-64G CB-RE, you must first uninstall
the backup CB-RE and install the REMX2K-X8-64G CB-RE, which then becomes the backup CB-RE.
Configure this backup CB-RE as the master CB-RE. Then replace the other CB-RE and configure it as the
backup CB-RE.
