Switch Management Port Failure (14 Blinks)
The Switch is operable. The Switch Management Port test verifies the integrity of the
Ethernet data bus functionality. A failure indicates that communication over the
Ethernet port will most likely be adversely affected when this failure is indicated. The
Heartbeat LED will blink fourteen times between three-second pauses. No port
Logged-in LEDs blink.
The remainder of the Switch and all ports have passed the tests and are operable.
Hung Flash Control Code
The Switch is not operable. If the Power Good LED is lit and the Heartbeat
LED and the remaining front-panel LEDs all blink in unison, the Flash control
code running the processor is hung.
Complete Failure
The Switch is not operable. If the Power Good LED is lit and the Heartbeat
LED does not blink at all (always ON or always OFF) the Switch is not operable.
