Verifying and Configuring the Upgraded Routing Engine as the Master
After replacing the backup Routing Engine with the RE-S-X6-64G Routing Engine, perform
the following steps:
1. Verify that the SCBE2 and RE-S-X6-64G Routing Engine are online by issuing the
show chassis hardware command.
2. After you install the RE-S-X6-64G Routing Engine into the SCBE2, the Routing Engine
gets automatically powered on and comes up in amnesiac mode as it is loaded with
factory defaults. After the Routing Engine comes up in amnesiac mode, load the base
configuration and commit.
3. Configure the backup Routing Engine by using the commit synchronize command to
copy the configuration to the backup Routing Engine.
4. Use the request chassis routing-engine master switch command to make the Routing
Engine RE-S-X6-64G (RE1) the master Routing Engine.All FPCs reboot after this step.
Verifying and Configuring the Upgraded Routing Engine as the Backup
1. Use the requestchassis routing-engine master switch command to make newly installed
RE-S-X6-64G (RE0) the backup Routing Engine.
2. Use the commit synchronize command to copy the active configuration from the
master Routing Engine to the backup Routing Engine.

Upgrading to the RE-S-X6-64G Routing Engine in a Nonredundant Host Subsystem
In a nonredundant host subsystem, only one Routing Engine and one Switch Control
Board are present in the chassis. When you are upgrading the Routing Engine, taking the
host subsystem offline shuts down the router. To upgrade the host subsystem with the
RE-S-X6-64G Routing Engine, you must uninstall the existing Routing Engine and install
the RE-S-X6-64G 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 MX240 SCB” on page 355 or Replacing an MX480 SCB or Replacing an
MX960 SCB, depending on the chassis on which the Routing Engine is being upgraded.
