Subsystem; Removing The Routing Engine - Juniper mx240 Hardware Manual

Upgrading to the RE-S-X6-64G Routing Engine in a Redundant Host Subsystem

Removing the Routing Engine

Copyright © 2016, Juniper Networks, Inc.
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
Replacing an MX480 SCB or Replacing an MX960 SCB, depending on the chassis on which
the Routing Engine is being upgraded.
NOTE: Save the router configuration before proceeding with the Routing
Engine upgrade.
