XRE200 Cooling System
The cooling system in an XRE200 External Routing Engine consists of two fan modules, left and right side
air intake, and exhaust openings in the power supplies. The fan modules are located in the fan module
slots on the back of the XRE200 External Routing Engine.
XRE200 External Routing Engines are shipped with fan modules installed in both fan module slots on the
rear panel of the chassis (see

We recommend that you install both fan modules in an XRE200 External Routing Engine whenever possible.
An XRE200 External Routing Engine can operate for a period of time with a single fan module; however,
the chassis might shut down when the high temperature threshold is exceeded if a fan module is not
available to properly cool the external Routing Engine.
Fan modules are hot-removable and hot-insertable field-replaceable units (FRUs).
