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. This is applicable when the RSP1 and RSP2 modules are installed in the chassis.
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. The following figure shows the front of the fan tray, including the handle and the captive installation screws.

Step 2 Grasp the fan tray handle with one hand and the outside of the chassis with the other hand.
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.
Step 3
Pull the fan tray backward toward you no more than 1 inch to disengage it from the power receptacle on the midplane,
as shown in the following figure.
