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.
If the Heartbeat LED shows the over temperature blink pattern, consider the ambient air temperature. Make
necessary corrections. If the condition remains, power down the switch and contact your authorized
maintenance provider.
