Fault
Sympto
m
The
chassis
where a
blade
server or
a high-
density
server is
located
has no
power.
Issue 20 (2020-09-25)
Handling Procedure
1. Check whether the external
power supply to the chassis is
normal or whether a power
overload has occurred.
2. Remove all compute nodes,
switch modules, management
modules and fan modules,
label them with the slot
numbers, and check whether
their power connectors are
normal.
3. Remove all PSUs, install the
PSUs back one at a time in
ascending order by slot number
(ensure that only one PSU is
installed at the same time),
and check whether the chassis
can be connected to the power
source. If the chassis cannot be
connected to the power source
no matter which PSU is
installed, replace the chassis.
4. If the chassis cannot be
connected to the power source
after a PSU is installed, replace
the PSU.
5. After verifying that the chassis
and PSUs can be connected to
the power source, install only
one PSU. Then install the
switch modules, compute
nodes, fan modules and
management modules one at a
time in ascending order by slot
number, and check whether the
module can be connected to
the power source.
6. After the fault is rectified,
install the switch modules,
compute nodes, fan modules
and management modules
back into their original slots.
