Figure 1-3 Wearing an ESD wrist strap
● Exercise caution when using tools to prevent injuries.
● If the position for installing the device is higher than your shoulders, use a
stacker to lift the device to prevent it from falling on top of you.
● High-voltage power supply provides power for device operation. Do not touch
high-voltage cables directly or through conductive materials. This may cause
danger of electrocution.
● Before powering on a device, ground it to prevent injuries.
● Do not use the ladder by yourself. Have someone else hold the ladder steady
to prevent accidents.
● Do not view the open optical port directly when installing, testing, or
replacing optical cables to prevent laser radiation from injuring your eyes.
Capacity Expansion Precautions
When expanding capacity, note the following:
● Use only genuine components that can be queried in the Intelligent
Computing Compatibility Checker.
● Only maintenance engineers authorized by Huawei are allowed to expand
capacity. Avoid physical damage caused by electrostatic discharge, collision,
and scratches.
● Before expanding capacity, back up data and isolate the equipment from the
network to prevent data loss, service interruption, and network loops.
● After expanding capacity, upgrade software to prevent software
incompatibility with new components.
Equipment Safety
To ensure equipment safety, note the following points:
● To ensure equipment and personal safety, use the recommended power
cables.
● Power cables can be used only for dedicated devices, and cannot be used for
any other devices.
● Before touching any devices, wear ESD clothing and gloves to avoid
electrostatic damage.
● When moving devices, hold device handles or the bottom of devices instead
of the handles of the installed modules (for example, a power module, fan
module, hard disk, or board).
