Additional Notes - Inspur NP5540M3 Manual

lowing measures:
1. If this happens after you plugged in some external board, you may need to pull
off this device and to do another test. If the alarm goes off, it shows that your external
board is incompatible with the machine. It is suggested not to use it any more; if the
alarm is still on, please go on referring to the following steps.
2. Locate the alarm sound:
● When the alarm sound is from the front of the chassis, usually we notice abnor-
mal changes of the fault indicating light. There is the possibility of abnormal fans or
hard disk module;
● If the alarm sound is from the rear of the chassis, please check whether a redun-
dant power supply is configured or not and whether there is an abnormal status light of
the power supply module or a module without power cable (when power alarm goes
on, the shield switch can be pressed to stop it);
● If the alarm sound is in the chassis, the alarm may be from motherboard, RAID
card or hard disk back plane. If it is also accompanied by no display on the monitor or
power on faults, there is high possibility of something wrong with motherboard. You
can try to pull or plug RAM or clear CMOS; if the starting self-check is normal and the
alarm starts when the RAID card is under test, and there is abnormal array information,
then it is likely that the RAID card has set off the alarm. There may be array abnormal-
ity; when the hard disk back plane alarms, there is always abnormal status light of the
hard disk on the front panel, which can be used to help analysis.
3. After having collected the basic information, please feedback the detailed alarm
information to Inspur technical support personnel in a timely manner. We will make
further analysis and judgment and help you solve the problem as soon as possible.
