Failure to POST
This platform relies on the Power button LED light blinking in an amber/white pattern to determine a failure as listed in the following table:
NOTE
The blinking patterns consists of two numbers (representing First Group: Amber blinks, Second Group: White blinks).
First Group: The Power button LED light blinks Amber, 1 to 9 times followed by a short pause with LED off for a couple of seconds.
Second Group: The Power button LED light then blinks White, 1 to 9 times, followed by a longer pause before the next cycle starts again after a short interval.
.
Example: No Memory detected (2,3). Power button LED blinks 2-times in Amber followed by a pause, and then blinks 3-times in White. The Power button LED will pause for few seconds before the next cycle repeats itself again.
