Handling Procedure Quick Recovery Method
The server
fails to
enter the
standby
mode
after it
powers
on. (The
power
indicator
is blinking
yellow for
over 5
minutes.)
1. View serial port logs to
determine whether the iMana
200 or iBMC has been
repeatedly reset.
If the iMana 200 or iBMC has
been repeatedly reset, the logs
repeatedly record the
following information:

NOTE
● The CH140 and CH140 V3
compute nodes of the E9000
do not provide any serial
ports. Directly ping the IP
address of the iMana 200 or
iBMC. If the ping tests
occasionally or always fail, use
the quick recovery method. If
the problem persists, contact
Huawei technical support.
● During the iMana 200 or
iBMC startup process, the
serial port on a server is used
by default. After the startup is
complete, the serial port is
switched for the system serial
port.
● During the iBMC startup
process, the serial port on a
server is used by default. After
the startup is complete, the
serial port is switched for the
system serial port.
For a rack server/Atlas 800 AI
inference server (model 3010)/
Atlas 800 AI training server
(model 9010), perform the
following operations:
1. Power
o the server,
remove and reinstall the
power cables, power on the
server, and check whether
the iMana 200 or iBMC is
functioning correctly.
● If yes, upgrade the iMana
200 or iBMC by using
software of its current
version or a later version.
● If no, check the iMana
200 or iBMC version. If
the version is 1.91 or
later, go to 2; otherwise,
go to 3.
2. Keep the power cables
removed and add a jumper
cap to the Clear_BMC_PW
pin on the mainboard to
attempt to restore the
default settings of the
iMana 200 or iBMC. Then
reconnect power cables.
3. Replace the mainboard or
BMC board.
For an E9000 server, perform
the following operations:
1. Remove and reinstall the
compute node and check
whether the iMana 200 or
iBMC is functioning
correctly.
● If yes, upgrade the iMana
200 or iBMC by using
software of its current
version or a later version.
● If no, check the iMana
200 or iBMC version. If
the version is 1.91 or
later, go to 2; otherwise,
go to 3.
