Problem
Descripon
EX Series switches generate a temperature alarm FPC 0 EX-PFE1 Temp Too Hot.
Cause
Temperature sensors in the chassis monitor the temperature of the chassis. The switch raises an alarm if
a fan fails or if the temperature of the chassis exceeds permissible levels.
Soluon
When the switch raises a temperature alarm such as the FPC 0 EX-PFE1 Temp Too Hot alarm, use the show
chassis environment and the show chassis temperature-thresholds commands to idenfy the condion that
triggered the alarm.
