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?
Yes - Continue.
No - Remove any debris from fan intake and exhaust if necessary. If
the condition remains, continue.
2. For a model 5602 switch, inspect the Power Supply Fault LED on both
power supplies; otherwise continue. Is the Power Supply Fault LED
illuminated on either power supply?
Yes - Replace the power supply. If the condition remains, continue.
No - Continue.
