A.4 During Boot-Up
Problem Possible Reason Solution
The module seems to
have powered up, but
there are no boot-up
prints on the console OR
the boot-up prints halt
midway. Module is under reset or is
being reset periodically. 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.
The carrier IPMC has
disabled payload power to
the module. Check if the Shelf manager/Carrier IPMC has
detected an overload/short circuit on the
payload power rail and has hence decided to
disable payload power to the module.
The processor has hung
during boot-up. The MMC monitors the POST codes of the
processor. System management firmware can
use the MMC to trace the stage at which
processor got stuck.
Serial port is not OK. Check if the connection of the serial port cable
to the console connector and to the terminal
PC is secure.
Ensure that a cross cable is used.
Check the settings (baud rate, flow-control,
etc.) of the terminal program.
Check the baud rate setting in the BIOS setup.
This should match the baud rate setting of the
terminal program.
Run out of battery. Check the battery set is well on socket.
Open / Close the handle again.
CMOS check sum failed. Removed the battery for more than
10 seconds and put it back, then power on
system.
