Saftety Instructions

General Statement

• Comply with local laws and regulations when installing devices. These Safety Instructions are only a supplement.
• The "DANGER", "WARNING", and "CAUTION" 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.
• This is a class A product, which may cause radio interference in a domestic environment. Take protective measures before operating this product in a residential area as it is likely to cause radio interference.

Human 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 device damage to a project supervisor.
• Do not move devices or install racks and power cables in hazardous weather conditions.
• Do not carry the weight that is over the maximum load per person allowed by local laws or regulations. Before moving or installing equipment, check the maximum equipment weight and arrange required personnel.
• Wear clean protective gloves, ESD clothing, a protective hat, and protective shoes, as shown in Figure 9-1.
  Figure 9-1 Safety work wear
  
• Before touching a device, wear ESD clothing and gloves (or wrist strap), and remove any conductive objects (such as watches and jewelry). Figure 9-2 shows conductive objects that must be removed before you touch a device.
  Figure 9-2 Removing conductive objects
  
  Figure 9-3 shows how to wear an ESD wrist strap.

  1. Put your hands into the ESD wrist strap.
  2. Tighten the strap buckle and ensure that the ESD wrist strap is in contact with your skin.
  3. Insert the ground terminal attached to the ESD wrist strap into the jack on the grounded rack or chassis.

• Exercise caution when using tools.
• If the installation position of the device is higher than the shoulders of the installation personnel, use a vehicle such as a lift to facilitate installation. Prevent the equipment from falling down and causing personal injury or damage to the equipment.
• The equipment is powered by high-voltage power sources. Direct or indirect contact (especially through damp objects) with high-voltage power sources may result in serious injury or death.
• Ground the equipment before powering it on. Otherwise, personal injury may be caused by high electricity leakage.
• When a ladder is used, ensure that another person holds the ladder steady to prevent accidents.
• When connecting, testing, or replacing an optical cable, do not look into the optical port without eye protection.

Equipment Safety

• Use the recommended power cables at all times.
• Use power cables only for dedicated servers. Do not use them for other devices.
• Before operating equipment, wear ESD clothes and gloves to prevent electrostatic-sensitive devices from being damaged by ESD.
• When moving a device, hold the bottom of the device. Do not hold the handles of the installed modules, such as the PSUs, fan modules, drives, and the mainboard. Handle the equipment with care.
• Exercise caution when using tools that could cause personal injury.
• If the device is configured with active and standby PSUs, connect power cables of active and standby PSUs to different power distribution units (PDUs) to ensure reliable system operating.
• Ground the equipment before powering it on.

Transportation Precautions

Improper transportation may damage equipment. Contact the manufacturer for precautions before attempting transportation.

Transportation precautions include but are not limited to:

• The logistics company engaged to transport the device must be reliable and comply with international standards for transporting electronics. Ensure that the equipment being transported is always kept upright. Take necessary precautions to prevent collisions, corrosion, package damage, damp conditions and pollution.
• Transport the equipment in its original packaging.
• If the original packaging is unavailable, package heavy, bulky parts (such as chassis and blades) and fragile parts (such as PCIe GPUs and SSDs) separately.

  Use Computing Product Compatibility Checker to obtain information abut the components supported by a node or server.

• Power off all devices before transportation.

Maximum Weight Carried by a Person

To reduce the risk of personal injury, comply with local regulations with regard to the maximum weight one person is permitted to carry.

Table 9-1 lists the maximum weight one person is permitted to carry as stipulated by a number of organizations.
