Safety Instructions

Safety Instructions

General Instructions

  • Comply with all local laws and regulations when installing the hardware. The safety instructions in this document are only supplemental to local laws and regulations.
  • Observe the safety instructions that accompany all "DANGER", "WARNING", "CAUTION", and "NOTICE" symbols in this document. These instructions are only supplemental to other safety measures.
  • When installing hardware, follow all safety instructions provided on the device labels and in this document.
  • Operations involving high voltages or moving equipment must be performed by authorized, qualified personnel.
  • Take protective measures before operating the device in residential areas as it is likely to cause radio interference.

Personal Safety

To ensure personal safety, note the following points:

  • Only personnel certified or authorized by Huawei are allowed to install the hardware.
  • Discontinue any dangerous operations and take protective measures. Problems that may cause personal injury or device damage should be immediately reported to the project supervisor.
  • Do not operate the product or handle cables during thunderstorms.
  • Exercise caution when using tools that could cause personal injury.
  • Use a stacker to lift a device above shoulder height. This will prevent it from falling.
  • Do not touch high-voltage cables directly or indirectly.
  • Before powering on a device, ensure that it has been properly grounded.
  • Do not use a ladder alone.
  • To avoid damaging your eyes when installing, testing, or replacing optical cables, do not look into optical ports without eye protection.
  • Wear clean protective gloves, ESD clothing, a protective hat, and protective shoes, as shown in Figure 1-1.
Figure 1-1 Protective clothing
  • Before carrying devices, note the following points:
    • Do not carry more weight than is permitted by local laws or regulations.
    • Arrange for enough personnel to carry the devices.
  • Before touching a device, ensure that you are wearing ESD clothing and ESD gloves (or wrist strap), and remove any conductive objects (such as watches and jewelry).

    Figure 1-2 shows conductive objects that must be removed before you touch a device.

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

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

Equipment Safety

  • Use the recommended power cables at all times.
  • Always use the power cables delivered with the devices.
  • Wear ESD clothing and gloves before handling a device. This prevents electrostatic damage.
  • When moving a device, make sure to hold the handles of the device (or the bottom of the devices). Do not hold the handles of the installed modules, such as power modules, fan modules, hard disks, or boards.
  • Exercise caution to prevent damage to the device when using tools during installation or maintenance.
  • Connect the power cables from the active power supply to one power distribution unit (PDU), and the cables from the backup power supply to another PDU.
  • Ensure that a device is properly grounded before powering it on.

Transportation Precautions

Exercise caution when transporting equipment.

  • 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 always upright. Take necessary precautions to prevent collisions, corrosion, package damage, damp conditions and pollution.
  • Transport the equipment in its original packaging.
  • Package heavy, bulky parts (such as chassis and blades) and fragile parts (such as PCIe GPUs and SSDs) separately.

Use the Intelligent Computing Compatibility Checker for details about parts supported by a server.

  • Ensure that all devices are powered off before transportation.
  • Do not transport hazardous materials.

For further details, contact the manufacturer.
