Heartbeat LED Blink Patterns

Normal (all pass)

If all POST diagnostics pass, the Switch will go to normal operation and the Heartbeat LED will blink at a steady rate of one (1) blink per second.

1 sec.

Failure Blink Patterns

The Heartbeat LED indicates the error by blinking a series of blinks, pausing for three seconds, then repeating the blinks. The number of blinks between the three- second pauses indicates the error. The blinks are at about twice the speed of the normal Heartbeat.
