In a PTX5000 packet transport router with a redundant host subsystem, Routing Engine
RE0 is the master Routing Engine and RE1 is the backup Routing Engine.
To upgrade the existing Routing Engine to the RE-PTX-X8-64G Routing Engine, perform
the following procedures:

Before you replace a Routing Engine, you must take the host subsystem offline. The host
subsystem is taken offline and brought online as a unit. Be aware of the effect of taking
a host subsystem offline on traffic, forwarding, and routing. See
Effect of Taking the PTX5000 Host Subsystem Offline" on page
To take a host subsystem offline:
Determine whether the Routing Engine to be replaced is currently functioning as the
