Over Temperature Blink Pattern

An over temperature blink pattern is 5 blinks followed by a two second pause. The
5-blink error pattern indicates that the air temperature inside the switch has
exceeded the failure temperature threshold. The failure temperature threshold is
70° C.
If the Heartbeat LED shows the over temperature blink pattern, do the following:
1. Inspect the chassis vents. Are the intake and exhaust vents clear?
2. Consider the ambient air temperature near the switch and clearance around
the switch. Make necessary corrections. If the condition remains, open a
command line window and log on to the switch. Enter the Shutdown
command, then power down the switch. Contact your authorized
maintenance provider.
