Error Codes 22
The LED blink pattern indicates the category of fatal error that occurred. The LED blinks the
HEX code for the error category. For instance, if the error is a memory test error, the LED
will blink 92, the HEX code for a memory test error. The LED will blink 9 times, pause, then
blink 2 times. After a longer pause, it will repeat the pattern. It will continue to repeat the
pattern until the watchdog timer resets the board as described above. Table 11-3 provides
the error categories associated with the blinking HEX codes.
