A.3 Fatal Hardware Self-Test Flash Codes
Fatal failures during startup are accompanied by an 8-bit fault code, flashed on the HLTH LED.
The fault code will be output MSB first, with a 1 (one) bit shown as a green LED, and a zero (0)
bit shown as a red LED. This will occur for a period of 900ms, followed by 100ms of off time.
The LSB will be followed by an additional 1000ms of off time, after which the sequence will
repeat.
The following table describes each possible fault code. If you see any of these codes, please
contact
