6.2.1 Power Supply and Distribution System Troubleshooting

Except mains outage, power supply and distribution faults are caused by the
damage or failure of one or more components. Rectify the faults based on fault
location and fault type.
● When a UPS is faulty, alarm information is displayed on the LCD. Critical alarms
must be handled before powering on the UPS again. Otherwise, the fault may
be extended, or the UPS may be damaged.
● If the fault is not rectified, contact Huawei technical support.
