Installing the Fan Tray

Caution The router can stay active for up to five minutes if the temperature is below the ambient limit. However, in the event of an overtemperature alarm, the router can shut down in less than five minutes. In the event of a critical temperature alarm, the router shuts down immediately.

Caution To avoid erroneous failure messages, allow at least 2 minutes for the system to reinitialize after the fan tray has been removed or replaced.

Follow these steps to remove and replace the fan tray on the Cisco ASR 903 Router:

Step 1 Using a No. 2 Phillips screwdriver or your fingers, loosen the captive installation screw that secures the fan tray to the chassis. Figure 3-12shows the front of the fan tray, including the captive installation screws.

Step 2 Grasp the fan tray handle with one hand and the outside of the chassis with the other hand. Figure 3-12shows the front of the fan tray, including the handle.

Caution The fans are exposed on the left side of the fan tray. Keep your fingers, clothing, and jewelry away from the fans. Always handle the fan tray by the handle.
