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 (70° C) and all ports are down.
If the Heartbeat LED shows the over temperature blink pattern:
1. Inspect the chassis fans and vents. Are the intake and exhaust vents clear? Are the fans
operating and producing air flow?
— 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, unplug the switch from the AC
power source, and contact your HP Authorized Maintenance Provider.
3. Open a command line window and log on to the switch. Enter the Shutdown command,
then power down the switch. Contact your HP Authorized Maintenance Provider.
