Chassis Cooling Requirements

The Cisco ASR 9000 Series supports version 1 and version 2 fan trays. Version 2 high-speed fans provide
additional cooling for new generation line cards that draw more power and generate more heat. This table
lists the chassis cooling requirements for these cards.

Cisco ASR 9922, V2 fan tray
Cisco ASR 9912, V1 fan tray
Cisco ASR 9010, V2 fan tray, low
power optics (less than 1.5W)
Cisco ASR 9010, V2 fan tray, high
power optics (greater than 1.5W)
Cisco ASR 9006 with baffle, V2 fan
tray
Cisco ASR 9904 with baffle, V1 fan
tray
Cisco ASR 9906, V1 fan tray
Cisco ASR 9910 Router with baffle,
V2 fan tray

Fan Tray Operation

The fan trays maintain acceptable operating temperatures for the internal components by drawing cooling air
through a replaceable air filter into the switch fabric and alarm card cage and then through the line card and
RSP card cage.
See the
The fan tray contains 12 fans (Cisco ASR 9010 Router, Cisco ASR 9904 Router, Cisco ASR 9910 Router,
Cisco ASR 9922 Router, and Cisco ASR 9912 Router), seven fans (Cisco ASR 9906 Router), or six fans
(Cisco ASR 9006 Router), a controller card, and one front panel status LED indicator:
