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.
CAUTION:
This equipment must be installed by trained service personnel, as defined by the NEC and IEC 60950-
1, Second Edition, the standard for Safety of Information Technology Equipment. Lenovo assumes you
are qualified in the servicing of equipment and trained in recognizing hazards in products with
hazardous energy levels.
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.
