Before you replace a control board or a Routing Engine, you must take the host subsystem
offline. The host subsystem is taken offline and brought online as a unit. Normally, if two
host subsystems are installed in the router,
as the backup. Table 41 on page 213 explains the effect of taking the host subsystem
offline.
Effect of taking the Host Subsystem Offline

The functioning of the router is not interrupted. The backup host subsystem is hot-removable
and hot-insertable.
