Safety Instructions

General Instructions

• Comply with all local laws and regulations when operating devices. These safety instructions are only a supplement.
• The "DANGER", "WARNING", "CAUTION", and "NOTE" information in this document does not represent all the safety instructions, but supplements to the safety instructions.
• Observe all safety instructions provided on the device labels when installing hardware. Follow them in conjunction with these safety instructions.
• Only qualified personnel are allowed to perform special tasks, such as performing high-voltage operations and driving a forklift.
• Take protective measures against radio interference before operating the device in residential areas.

Personal Safety

• Only personnel certified or authorized by Huawei are allowed to install devices.
• Discontinue any dangerous operations and take protective measures. Report anything that could cause personal injury or equipment damage to a project supervisor.
• Do not move devices or install cabinets and power cables in hazardous weather conditions.
• The average weight carried by a person cannot exceed the maximum acceptable weight of lift (MAWL) allowed by local safety regulations. Before moving a device, check the maximum device weight and arrange required personnel.
• Wear clean protective gloves, ESD clothing, a protective hat, and protective shoes, as shown in Figure 1-1.

Figure 1-1 Protective clothing

• Before contacting devices, wear antistatic clothing and ESD gloves, and take off electricity-conductive materials such as watches and jewelries, as shown in Figure 1-2.

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

1. Secure the wrist strap around your wrist.
2. Fasten the strap buckle and ensure that the ESD wrist strap is snug against the skin.
3. Insert the attached ground terminal into the jack on the grounded rack or chassis.

• Exercise caution when using tools that could cause personal injury.
• Use a stacker when lifting hardware above shoulder height.
• Avoid any contact with high-voltage cables.
• Ensure that the device is properly grounded before powering it on.
• Never use a ladder if you are alone and cannot get assistance.
• Do not look into optical ports without eye protection when installing, testing, or replacing optical cables.

Equipment Safety

• Use dedicated power cables to ensure equipment and personal safety.
• Use power cables only for dedicated devices.
• When moving a device, hold the handles or bottom of the device. Do not hold the handle of the installed module, such as a power module, fan module, drive, or mainboard.
• Connect the power cables of the active and standby PSUs to different PDUs to ensure reliable system operation.

Transportation Precautions

• Hire certified logistics companies to transport the equipment complying with international standards for transporting electronics. Ensure that the equipment being transported is always kept upright. Take necessary precautions against collisions, corrosion, moisture, package damage, and contamination.
• Transport the equipment in its original packaging.
• If original packages are not used, package heavy, bulky items (such as chassis) and fragile components (such as PCIe cards and optical modules) separately.

Use the Computing Product Compatibility Checker to query the components supported by the node or server.

• Power off all equipment before transportation. Do not transport hazardous materials.

Maximum Acceptable Weight of Lift (MAWL)

To reduce the risk of personal injury, comply with local regulations with regard to the MAWL.

Table 1-1 lists the maximum weight each person is permitted to carry by standards organization.
