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.
