Page 12

5288 V3 Server User Guide

1 Safety Instructions

l Wear clean protective gloves, ESD clothing, a protective hat, and protective shoes, as

shown in Figure 1-2.

Figure 1-2 Protective clothing

Figure 1-3 shows how to wear an ESD wrist strap.

1. Put on the ESD wrist strap.

2. Fasten the buckle and ensure that the ESD wrist strap is in good contact with your skin.

3. Insert the ground terminal of the ESD wrist strap into the jack on the grounded cabinet or chassis.

Figure 1-3 Wearing an ESD wrist strap

l Exercise caution when using tools to prevent injuries.

l 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.

l 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.

Page 13

5288 V3 Server User Guide

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.

1 Safety Instructions

Capacity Expansion Precautions

l Use only genuine components that can be queried in the Huawei Server Compatibility

Checker.

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.

6 SD card SD cards use flash memory and SPIs to store data. Currently, NAND

flash memory is mostly used in the industry. NAND flash memory

stores electrons on the floating gate to store data. However, electrons

frequently passing through the floating gate will weaken the gate's

ability to store electrons and eventually make the gate unable to store

electrons. This problem is common to NAND flash memory. The

amount of service data to be written needs to be assessed to prevent

component failures.

NOTE

l An SD card can be used only as a boot device for OSs. l SD cards have weak endurance and cannot be used as data storage devices.

Use enterprise-level HDDs or SSDs to replace SD cards for data storage when frequent data erase operations are involved.

l Installing write-intensive service software on SD cards will accelerate the

write life consumption and result in perpetual damage of SD cards. SD cards cannot be used for such services.

l SD cards cannot be used in cache scenarios.

7 Dual-SD

card module

Provides two SD card slots. Each slot supports an SD card of up to 32

GB. SD cards can be used as the boot media of the server. After the

iBMC initialization is complete, two SD cards are configured as a

RAID 1 array when being detected. You can view the information

about the SD cards and RAID 1 array on the iBMC WebUI by

choosing System Info > Other, but cannot modify the configuration

or manually configure them.

l Ensure that the length of cable ties for binding cables is appropriate. Do not connect two

or more cable ties together for binding cables. After binding cables properly, trim off the excess lengths of the cable ties and ensure that the cuts are neat and smooth.

l Ensure that cables are properly routed, supported, or fixed within the cable troughs

inside the cabinet to prevent loose connections and cable damage.

l Coil any surplus lengths of cables and bind them to proper positions inside the cabinet. l Route cables straightly and bind them neatly. The bending radius of a cable varies with

the position where the cable is bent. – If you need to bend a cable in its middle, the bending radius must be at least twice

the diameter of the cable.

– If you need to bend a cable at the output terminal of a connector, the bending radius

must be at least five times the cable diameter, and the cable must be bound before bending.

– Do not use cable ties at a place where the cables are bent. Otherwise, the cables

may break.

Common Cable Routing Methods

The methods of routing cables inside a cabinet are described as follows:

l Determine overhead cabling and underfloor cabling for power cables based on specific

conditions of the equipment room. For example, take into consideration the AC power distribution frame (PDF), surge protector, and terminal block.

l Determine overhead cabling and underfloor cabling for service data cables based on

specific conditions of the equipment room.

l Place the connectors of all service Ethernet cables at the bottom of the cabinet in order so

that the connectors are difficult to reach.

Cable Routing Rules

To ensure optimal heat dissipation, do not block the air exhaust vents of PSUs.

3.5.8 Verifying Cable Connections

Before verifying cable connections, ensure that the power is off. Any incorrect or loose connection may cause personal injury or equipment damage.
