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. Inspect the Power Supply Fault LED on both power supplies. Is the Power
Supply Fault LED illuminated on either power supply?
„
Yes - Replace the power supply. If the condition remains, continue.
„
No - Continue.
3. Observe the air flow direction from both power supplies. Are they 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.
