During or After System Initialization
Problem Possible Reason Solution
The blue hot-swap LED
does not glow after inserting
the board.
The board has not mated completely
with the backplane connectors.
1: Ensure that the board is fully inserted and
seated properly.
2: Remove the board and check the board’s
backplane connectors for any damage.
The carrier has not enabled
Management Power.
1: Check if the Shelf Manager/Carrier IPMC
has detected the board.
2: Check if the Shelf Manager/Carrier IPMC
has detected a short circuit or overload on
the Management power rail.
No management support for blue LED
exists (on prototype boards).
If you are using a prototype carrier, the IPMC
may not support the blue LED functionality,
yet. Check with your vendor to confirm.
Board fails to power up. Backplane voltages not within the
specified range.
1: Check if all backplane voltages are within
their specific ranges.
2: Check if power supply is capable to drive
the respective loads.
Board defect Replace board
Damaged plugs, bent or broken pins:
backplane defect
1: Check for bent or broken pins in the ATCA
slot used.
2: Replace backplane.
The carrier IPMC has not enabled
Payload power.
1: Check if the Shelf Manager/Carrier IPMC
has detected the newly inserted board.
2: Check if the Shelf Manager/Carrier IPMC
has determined that the onboard devices’
power requirement is more than what can
be supplied. If so, analyze if the carrier can
really support the onboard devices’ power
requirements.
3: Check if there is a short circuit on the
Payload power (12V) rail.
An onboard power supply regulator
has failed.
Check if the IPMC has reported a local power
failure.
