Routing Engine Module in an EX9200 Switch
The Routing Engine module (RE module) is an Intel-based platform that runs Juniper
Networks Junos operating system (Junos OS). Software processes that run on the RE
module maintain the routing tables, manage the routing protocols used on the switch,
control the router interfaces and some of the chassis components, and provide the
interface for system management and user access to the switch.
In an EX9204, EX9208, or EX9214 switch, you can install one or two RE modules in the
Switch Fabric modules (SF modules) that are installed in slots on the front panel of the
switch. If you install two RE modules, one functions as the master and the other functions
as the backup. If the master RE module fails or is removed and the backup is configured
appropriately, the backup takes over as the master. The backup RE module is
hot-insertable and hot-removable, whereas the master RE module is only hot-insertable.
