102
Possible Reason
The module has not mated
completely with the AMC
connector on the carrier.
The carrier has not enabled
Management Power to the
module.
The carrier IPMC has not
enabled payload power to the
module.
An onboard power supply
regulator has failed.
Possible Reason
Module is under reset or is
being reset periodically.
PrAMC-7311 Installation and Use (6806800P34F)
Solution
Ensure that the module is fully inserted
and seated properly, such that the module
face plate is flush with the carrier's face
plate.
Check the module PCB edge connector
for any damage to the conductive traces
forming the edge connector.
Check if the Shelf Manager/Carrier IPMC
has detected the newly inserted module.
Check if the Shelf Manager/Carrier IPMC
has detected a short circuit or overload on
the Management power rail.
Check if the Shelf Manager/Carrier IPMC
has detected the newly inserted module.
Check if the Shelf Manager/Carrier IPMC
has determined that the module power
requirement is more than what can be
supplied. If so, analyze if the carrier can
really support the module power
requirements.
Check if there is a short circuit on the
Payload power (12V) rail.
Check if the MMC has reported a local
power-up failure to the IPMC.
Solution
Check if the carrier IPMC has issued a Cold
Reset IPMI command to the module for some
reason, thereby preventing the module from
booting up.
Check if the MMC has reported a watchdog
expiry event on the module.
