The host subsystem is taken offline and brought online as a unit. Before you replace a
CB or a Routing Engine, you must take the host subsystem offline.
Normally, if two host subsystems are installed in the router,
and functions as the backup. You can remove the backup host subsystem (or either
RE1
of its components) without interrupting the functioning of the router. If you take the
master host subsystem offline, the backup host subsystem becomes the master (the
router might reboot, depending on your configuration). If the router has only one host
subsystem, taking the host subsystem offline causes the router to shut down.
