2 Processing flow
Fault handling refers to the use of reasonable methods to gradually find out the cause of
the fault and solve it. Its guiding ideology is to reduce (or isolate) a large set of possible causes
of faults into several small subsets, so as to reduce the complexity of the problem rapidly,
finally find the root cause of the problem, and take appropriate measures to eliminate it.

4 Fault diagnosis and treatment
4.1 Diagnostic principle
All operations shall ensure that business data will not be lost or backed up.
When troubleshooting, please follow the following basic principles:
diagnose the outside first, then diagnose the inside. When diagnosing faults, external
possible factors, such as power supply interruption and docking equipment faults, should
be eliminated first.
diagnose the network first, then the network element.
According to the network topology diagram, analyze whether the network environment is
normal and whether the interconnection equipment fails, and locate which network
element in the network has failed as accurately as possible.
high speed part first, then low speed part.
It can be seen from the alarm signal flow that the alarm of high-speed signal often causes
the alarm of low-speed signal. Therefore, in the fault diagnosis, the fault of the high-speed
part should be eliminated first.
analyze high-level alarms first, then analyze low-level alarms.
When analyzing alarms, first analyze high-level alarms, such as emergency alarms and
serious alarms, and then analyze low-level alarms, such as minor alarms.
4.2 Troubleshooting according to the alarm
According to the management system (BMC) of the server, the alarm information is
checked, and diagnosis and fault location are carried out.
The BMC event log can be viewed in the BMC interface and is divided into three levels:

information, warning and critical
1、The information log mainly contains normal records, including the startup and
shutdown of the server and the normal status monitored by some hardware (hard disk,
power supply, etc.) during startup.
2、The warning log mainly contains some problems that are alarming but do not cause
machine downtime, but need attention and repair. At this time, the alarm indicator
on the front panel of the machine will give an alarm. Including non-serious error
reporting, memory correctable ECC error, etc.
3、The critical log mainly contains critical errors or unrecoverable errors that may cause
machine downtime, including low/high fan speed, high/low temperature, high/low
voltage, uncorrectable ecc errors in memory, etc.
4.3 Locate the fault according to the indicator
4.3.1 Front panel indicator
Locate the fault according to all kinds of indicators on the server panel. Figure 5-4 below
shows the indicators on the front panel of NF8480M5. The specific lighting meanings are
shown in Table 5-1.
