Hi Sameer

Temperature alarm means that one particular sensor on the linecard warms up to 101 degree.

This can be caused by damaged sensor or problems with cooling in that particular part of chassis.

You can check temperature on the module using following command:

show environment temperature module 1

Tru to move the module to another slot. If the issue reoccure - open a TAC case.
