[c-nsp] GSR 12008 (%ENV_MON-2-FAN)

[Chris Lane]

I am getting error
%ENV_MON-2-FAN: Fan array has reached CRITICAL level.


I did a search and found this on Ciscos website.
------------------------------------------------------------------------
%ENV_MON-2-FAN : Fan array has reached [chars] level.

Explanation    There might be a hardware problem with the fan array. If the
error condition continues for two minutes, the router shuts down
automatically to prevent damage to router components.
Recommended Action    If the system shuts down, replace the fan tray. Copy
the error message exactly as it appears on the console or in the system log,
contact your Cisco technical support representative, and provide the
representative with the gathered information.
---------------------------------------------------------------------------
I have just removed CSC cards and fan tray. Same symptoms.
I also must mention the alarm state is short unlike the 2minutes stated
above.
Mar 18 05:26:18.257 EST: %ENV_MON-2-FAN: Fan array has reached CRITICAL
level.
Mar 18 05:26:21.066 EST: %ENV_MON-2-FAN: Fan array has reached CRITICAL
level.

As you can see no errors are incrementing on the SFC or CSC.

I am stumped.

Any suggestions would be greatly appreciated.
