Safety inspection checklist

Use the information in this section to identify potentially unsafe conditions with your server. As each machine was designed and built, required safety items were installed to protect users and service technicians from injury.

Note
The product is not suitable for use at visual display workplaces according to §2 of the Workplace Regulations.
Note
The set-up of the server is made in the server room only.
CAUTION
  • This equipment must be serviced by trained personnel, as defined by the IEC 62368-1, the standard for Safety of Electronic Equipment within the Field of Audio/Video, Information Technology and Communication Technology. Lenovo assumes you are qualified in the servicing of equipment and trained in recognizing hazards energy levels in products. Equipment must be installed in a restricted access location and access to the equipment is controlled by the authority responsible for the location.
  • Consult with the supply authority, if necessary, that the equipment is connected only to a supply of Zmax 0.105 for IEC 61000-3-11 compliance.
Important
Electrical grounding of the server is required for operator safety and correct system function. Proper grounding of the electrical outlet can be verified by a certified electrician.
Use the following checklist to verify that there are no potentially unsafe conditions:

  1. Make sure that the power is off and the power cord is disconnected.

  2. Check the power cord.

    • Make sure that the third-wire ground connector is in good condition. Use a meter to measure third-wire ground continuity for 0.1 ohm or less between the external ground pin and the frame ground.

    • Make sure that the power cord is the correct type.

      To view the power cords that are available for the server:

      1. Go to:

        Data Center Solution Configurator

      2. Click Preconfigured Model or Configure to order.

      3. Enter the machine type and model for your server to display the configurator page.

      4. Click Power > Power Cables to see all line cords.

    • Make sure that the insulation is not frayed or worn.

  3. Check for any obvious non-Lenovo alterations. Use good judgment as to the safety of any non-Lenovo alterations.

  4. Check inside the server for any obvious unsafe conditions, such as metal filings, contamination, water or other liquid, or signs of fire or smoke damage.

  5. Check for worn, frayed, or pinched cables.

  6. Make sure that the power-supply cover fasteners (screws or rivets) have not been removed or tampered with.

  7. The design of the electrical distribution system must take into consideration the total grounding leakage current from all power supplies in the server.

    CAUTION


    High touch current. Connect to earth before connecting to supply.

  8. Use the PDUs (power distribution units) with pluggable equipment type B to distribute electrical power to servers.
