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 installed or serviced by trained personnel, as defined by the NEC, IEC 62368-1 & IEC 60950-1, the standard for Safety of Electronic Equipment within the Field of Audio/Video, Information Technology and Communication Technology. Lenovo assumes that you are qualified in the servicing of equipment and trained in recognizing hazards energy levels in products. Access to the equipment is by the use of a tool, lock and key, or other means of security, and is controlled by the authority responsible for the location.
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. If your working condition necessitates the server being powered off or you intend to power off, make sure that the power cord is disconnected.

    S002
    disconnect all power
    CAUTION
    The power-control button on the device and the power switch on the power supply do not turn off the electrical current supplied to the device. The device also might have more than one power cord. To remove all electrical current from the device, ensure that all power cords are disconnected from the power source.
    Note
    Under certain circumstances, powering off the server is not a prerequisite. Refer to the precautions before conducting any tasks.

  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 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.
