l
Before powering on a device, ground it to prevent injuries.
l
Do not use the ladder unsupervised. Have someone else hold the ladder steady to prevent
accidents.
l
Do not view the open optical port directly when installing, testing, or replacing optical
cables to prevent laser radiation from injuring your eyes.
Transportation Precautions
Contact the manufacturer for precautions before attempting transportation.
l
The logistics company engaged to transport the equipment must be reliable and comply
with international standards for transporting electronics. Ensure that the equipment being
transported is kept upright and avoid collision, damp conditions, corrosion, package
damage, and pollution.
l
Transport the equipment in its original packaging.
l
Package fragile parts such as optical modules, PCIe SSDs, and GPUs separately from
bulky items such as chassis.
l
Power off all equipment before transportation. Do not transport hazardous materials.
Capacity Expansion Precautions
l
Use only genuine components that can be queried in the
.
l
Only maintenance engineers authorized by Huawei are allowed to expand capacity.
Avoid physical damage caused by electrostatic discharge, collision, and scratches.
l
Before expanding capacity, back up data and isolate the equipment from the network to
prevent data loss, service interruption, and network loops.
l
After expanding capacity, upgrade software to prevent software incompatibility with new
components.
Equipment Safety
l
To ensure equipment and human safety, use the recommended power cables.
l
Power cables can be used only for dedicated devices, and they cannot be used for any
other devices.
l
Before touching devices, wear ESD clothing and gloves to avoid electrostatic damage.
l
When moving devices, hold the handles or bottom of devices instead of the handles of
the installed modules (for example, a PSU, fan module, hard disk, or board).
l
Exercise caution when using tools to avoid equipment damage.
l
Connect the power cables to different power distribution units (PDUs) so that the PDUs
can supply power to the device in active/standby mode. This improves power supply
reliability.
l
Before powering on a device, ground it to prevent device damage.
