The backup Routing Engine is hot-insertable and hot-removable, but the master Routing
Engine is hot-pluggable. If only one RE module is installed, you must disable the switch
before removing the RE module.
A base configuration EX9204 and EX9208 switch has only one RE module. See EX9204
Switch Configurations and EX9208 Switch Configurations. You can add a second RE
module to the configuration for a redundant host subsystem.
A base configuration EX9214 switch has two RE modules. See
Configurations" on page 7. You can add a third RE module to the configuration for a
redundant host subsystem.
Figure 14 on page 28 shows the RE module in an EX9200 switch.
