Replacing the Fan Tray

The fan tray supports online insertion and removal (OIR). There is no need to power down the Cisco ASR

914 Router to remove or replace the fan tray. Only one fan tray can be removed or replaced at a time. However,

the router will shut down if the fan tray is removed for more than 5 minutes at 30º C. If more than one fan

tray is removed the system will shut down immediately. Once the thermal overload condition is absent, the

system attempts to power up automatically, if the fan tray is re-inserted and the system temperature is within

limits. Approximately at 25º C the system powers back in 2 minutes.

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.

Caution

The router can stay active for up to 60 seconds if the temperature is below the ambient limit. 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 removed or replaced.
