Upgrading To The Re-S-X6-64G Routing Engine In A Redundant Host Subsystem; Removing The Routing Engine - Juniper MX480 Hardware Manual

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,
page 422or 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 .

Removing the Routing Engine
To remove the backup Routing Engine from the chassis (see
and Figure 108 on page
1. On the external management device connected to the Routing Engine, shut down the host subsystem
by using the request system power-off command.
2. Wait until a message appears on the console confirming that the operating system has halted.
