Alarm Generated for Fabric cores on PA-7050 for temperature high

[tamilvanan]

Hi Team, 

We are now constantly getting alarm for Fabric Cores of the firewall and the power supply and the FAN tray looks good. 

We are also keeping the device in Air Conditioned room.

Does the alarm may be generated due to some issue with the firewall internally.
