Safety Instructions

Safety Instructions

This section recommends the safety measures to follow when you install or replace a server or its parts.

General Instructions

The following general information is recommended:

  • Comply with local laws and regulations when installing the hardware. The safety instructions in this document are only supplements to the local laws and regulations.
  • "CAUTION", "WARNING", "DANGER", and "NOTICE" notices in this document are only supplements to the safety instructions in this document.
  • To ensure personal and device safety, follow all safety instructions on device labels and in this document when installing the hardware.
  • Only personnel (such as electricians and forklift operators) who are authorized or certified by governments or official organizations are allowed to perform hardware installation.
  • This product is a Class A device. Take protective measures before operating this product in a residential area 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 perform the hardware installation.
  • In case of any problems that may cause injury to personnel or damage to devices, immediately stop operations and report the problems to a project supervisor and take protective measures.
  • Do not perform operations such as moving devices, installing cabinets, and installing power cables on rainy days or during thunderstorms.
  • 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 than allowed by the local laws or regulations.
    • Arrange for enough personnel to carry the devices.
  • Before touching any devices, wear 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 1-2 Conductive objects to be removed

    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 in contact against your skin.
    3. Insert the ground terminal attached to the ESD wrist strap into the jack on the grounded cabinet or chassis.

  • Exercise caution when using tools to prevent injuries.
  • 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.
  • 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.
  • Before powering on a device, ground it to prevent injuries.
  • Do not use the ladder by yourself. Have someone else hold the ladder steady to prevent accidents.
  • Do not view the open optical port directly when installing, testing, or replacing optical cables to prevent laser radiation from injuring your eyes.

Capacity Expansion Precautions

When expanding capacity, note the following:

  • Use only genuine components that can be queried in the Intelligent Computing Compatibility Checker.
  • Only maintenance engineers authorized by Huawei are allowed to expand capacity. Avoid physical damage caused by electrostatic discharge, collision, and scratches.
  • Before expanding capacity, back up data and isolate the equipment from the network to prevent data loss, service interruption, and network loops.
  • After expanding capacity, upgrade software to prevent software incompatibility with new components.

Equipment Safety

To ensure equipment safety, note the following points:

  • To ensure equipment and personal safety, use the recommended power cables.
  • Power cables can be used only for dedicated devices, and cannot be used for any other devices.
  • Before touching any devices, wear ESD clothing and gloves to avoid electrostatic damage.
  • When moving devices, hold device handles or the bottom of devices instead of the handles of the installed modules (for example, a power module, fan module, hard disk, or board).
  • Exercise caution when using tools to avoid equipment damage.
  • 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.
  • Ensure that a device is properly grounded before powering it on.

Transportation Precautions

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

Such precautions include but are not limited to:

  • 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.
  • Transport the equipment in its original packaging.
  • Package fragile parts (such as optical modules and PCIe GPUs and SSDs) separately from bulky items (such as chassis and blades). See the compatibility list for details about parts supported by a compute node or server.

    Use the Intelligent Computing Compatibility Checker to check parts supported by compute modules or the server.

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

Limits for the Maximum Weight Carried Per Person

To reduce the risk of personal injury, comply with local regulations regarding the limits for the maximum weight carried per person.
