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.

For a model 5202/5602 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.

3.

For a model 5202/5602 switch, observe the air flow direction from both 
power supplies; otherwise continue. Are the flow directions the same?
„

Yes - Continue.

„

No - Determine the proper air flow direction for the switch. Replace the 
power supply with the incorrect air flow direction with another having 
the correct air flow direction. Air flow direction is marked on the power 
supply part number label. If the condition remains, continue.

4.

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.
