Fan Tray

The Cisco ASR 903 Router uses a modular fan tray that is separate from the power supply. The fan tray contains twelve fans and provides sufficient capacity to maintain operation indefinitely in the event of an individual fan failure.

The fan tray has the following hardware features:

•It provides side-to-side forced air cooling

•It provides redundant fans

•It is field replaceable

•It contains status LEDs

•It contains an alarm port with four external alarm inputs
