A redundant host subsystem consists of a master Routing Engine (RE0) and a backup
Routing Engine (RE1). To upgrade the host subsystem to use the RE-S-X6-64G Routing
Engine, you must first uninstall the backup Routing Engine and install the RE-S-X6-64G
Routing Engine, which then becomes the backup Routing Engine. You then switch over
this backup Routing Engine to make it the master Routing Engine. Replace the other
Routing Engine and configure it as the backup Routing Engine.
Ensure that the Switch Control Board in the chassis is SCBE2 because the RE-S-X6-64G
Routing Engine is not compatible with the Switch Control Boards SCB or SCBE. To upgrade
the Switch Control Board to SCBE2, see Upgrading an MX240 to Use the SCBE2-MX,
"Upgrading an MX480 to Use the SCBE2-MX" on page
the SCBE2-MX, depending on the chassis on which the Routing Engine is being upgraded.
NOTE: Save the router configuration before proceeding with the Routing
Engine upgrade.
