Removing and Replacing the Fan Tray
The fan tray supports online insertion and removal (OIR). There is no need to power down the Cisco ASR
907 Router to remove or replace the fan tray. However, the router will shut down if the fan tray is removed
from the chassis for more than 90 seconds at 25º C due to thermal overload condition. Approximately at 25º
C the system powers back in 2 minutes.
If a fan tray is removed and not replaced within the stipulated time the system will automatically power-off.
If the system is powered with PSUs other than 900W DC or 1200W AC and if the system is powered off,
then the system should be completely powered off for 30 seconds with all the PSU in the system simultaneously,
and then turned on for the system to power on.
Note
Do not introduce body parts or objects in the fan tray slot when installing or removing the fan tray module.
Exposed circuitry is an energy hazard.
Note
The router can stay active for up to 60 seconds if the temperature is up to 30º C. However, in the event of an
overtemperature alarm, the router can shut down in less than 60 seconds. 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 replaced.
