2. Contact Huawei technical
support.
2. Keep the compute node
removed and add a jumper
cap to the Clear_BMC_PW
pin on the mainboard to
attempt to restore the
default settings of iMana
200 or iBMC. Then reinstall
the compute node.
3. Replace the mainboard or
BMC board.
A server
in standby
mode
cannot
power on.
(The
power
indicator
is steady
yellow.)
1. Collect iMana 200 or iBMC
logs, and query the complex
programmable logical device
(CPLD) register to determine
whether the power supply link
to the mainboard has failed.
2. If the server cannot be
powered on by pressing the
power button, check whether
the hardware of the
component where the power
button is located is faulty.
3. Check whether the mainboard
and DIMMs are installed
properly.
1. Remove the external PCIe
devices such as NICs and FC
HBAs. Then check whether
the fault is rectied.
● If yes, no further action is
required.
● If no, go to 2.
2. Retain only the minimum
server
conguration (a
single CPU, a single
mainboard, and a single
DIMM). Then check whether
the fault is
rectied.
● If yes, no further action is
required.
● If no, go to 3.
3. Check whether the CPUs,
mainboard, and memory
modules are faulty, and
replace the faulty
components.
