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.
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?
„
Yes - Continue.
„
No - Remove any debris from fan intake and exhaust if necessary. If
the condition remains, continue.
2. Consider the ambient air temperature near the switch and clearance around
the switch. Make necessary corrections. If the condition remains, power
down the switch, then contact your authorized maintenance provider.
