Figure 10: Airflow through the Chassis
The router cooling system consists of a fan tray that installs into the chassis from the rear, as shown in Figure 3. It houses four fans, which draw room air into the chassis to keep the internal temperature below a maximum acceptable level. The air flows side-to-side in the chassis, as shown in Figure 10.

The fan tray is hot-removable and hot-insertable, as described in Field-Replaceable Units (FRUs). For instructions on replacing it, see Replace the Fan Tray.

Do not remove the fan tray for more than a about one minute while the router is operating. The fans are the sole source of cooling, and the router can overheat when they are absent. |
