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.

Fatal POST 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 your authorized maintenance 
provider. Momentarily press and release the Maintenance button to reset the 
switch.
