Upgrading to the RE-S-X6-64G Routing Engine in a Redundant Host
Subsystem
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" on page
SCBE2-MXor Upgrading an MX960 to Use 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.
NOTE: Nonstop active routing (NSR) and graceful Routing Engine switchover (GRES) are not
supported during the upgrade and they must be temporarily disabled. Disable NSR by removing
the nonstop-routing statement from the [edit routing-options] hierarchy level and by removing
the graceful-switchover statement from the [edit chassis redundancy] hierarchy level .
