Heartbeat LED Blink Patterns
The Heartbeat LED indicates the operational status of the switch. When the POST completes with
no errors, the Heartbeat LED blinks at steady rate of once per second. When the switch is in
maintenance mode, the Heartbeat LED illuminates continuously. All other blink patterns indicate
critical errors. In addition to producing a Heartbeat error blink patterns, a critical error also
illuminates the System Fault LED. The Heartbeat LED shows an error blink pattern for the following
conditions:
•
2 blinks - Internal Firmware Failure Blink Pattern
•
3 blinks - System Error Blink Pattern
•
4 blinks - Configuration File System Error Blink Pattern
•
5 blinks - Over Temperature Blink Pattern
Internal Firmware Failure Blink Pattern—An internal firmware failure blink pattern is 2 blinks
followed by a two second pause. The 2-blink error pattern indicates that the firmware has failed,
and that the switch must be reset. Momentarily press and release the Maintenance button to reset
the switch.
System Error Blink Pattern—A system error blink pattern is 3 blinks followed by a two second
pause. The 3-blink error pattern indicates that a POST failure or a system error has left the switch
inoperable. If a system error occurs, contact HP support. Momentarily press and release the
Maintenance button to reset the switch.
Configuration File System Error Blink Pattern—A configuration file system error blink pattern is 4
blinks followed by a two second pause. The 4-blink error pattern indicates that a configuration file
system error has occurred. Contact HP support.
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.
