Fan Modules in an XRE200 External Routing Engine

Fan modules provide cooling to an XRE200 External Routing Engine. All XRE200 External Routing Engines are shipped with fan modules installed in both fan module slots on the rear panel of the chassis. See Figure 1.

Figure 1: Fan Module

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).
