I have this problem too.

Hi Deepa,

The current temparature for module 1,2 and 3  are showing 42 'C whch is at warining level, check out the following thisngs and parameters

To view the acceptable temperature and voltage parameters, use the 'show environment alarm thresholds' command. To return the current temperature to normal parameters make sure the device is installed in:

A site with a dry, clean, well-ventilated and air-conditioned area. Make sure   that the air conditioner is working correctly.

A site that maintains an ambient temperature of 32 to 104º F (0 to 40º C).

Install the system in an open rack whenever possible. If installation in an enclosed rack is unavoidable, ensure that the rack has adequate ventilation.


Maintain ambient airflow to ensure normal operation. If the airflow is blocked or restricted, or if the intake air is too warm, an overtemperature condition  can occur.


Allow at least 6 inches (15.24 cm) of clearance around the ventilation openings of the chassis.


Avoid placing the system in an overly congested rack or directly next to another equipment rack. Heat exhaust from other equipment can enter the inlet air vents and cause an overtemperature condition.


Equipment near the bottom of a rack might generate excessive heat that is drawn upward and into the intake ports of the equipment above. The warm air can cause an overtemperature condition in the equipment above.


Ensure that cables from other equipment do not obstruct the airflow through the   chassis or impair access to the power supplies or cards. Route cables away   from field-replaceable components to avoid disconnecting cables unnecessarily   for equipment maintenance or upgrades.


If the module temperature sensor does not recover by itself then plan a downtime and power cycle the module.

Hope this helps out your query !!

If helpful do rate the valaubale post.
