Guidelines for trained service technicians

vDo not remove any air duct or air baffles while the server is running. Operating the server without the air duct or air baffles might cause the microprocessor to overheat.

vThe second microprocessor socket always contains either a microprocessor socket cover or a microprocessor.

Inspecting for unsafe conditions

Use the information in this section to help you identify potential unsafe conditions in a Lenovo product that you are working on. Each Lenovo product, as it was designed and manufactured, has required safety items to protect users and service technicians from injury. The information in this section addresses only those items. Use good judgment to identify potential unsafe conditions that might be caused by non-Lenovo alterations or attachment of non-Lenovo features or options that are not addressed in this section. If you identify an unsafe condition, you must determine how serious the hazard is and whether you must correct the problem before you work on the product.

Consider the following conditions and the safety hazards that they present:

vElectrical hazards, especially primary power. Primary voltage on the frame can cause serious or fatal electrical shock.

vExplosive hazards, such as a damaged CRT face or a bulging capacitor.

vMechanical hazards, such as loose or missing hardware.

To inspect the product for potential unsafe conditions, complete the following steps:

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

2.Make sure that the exterior cover is not damaged, loose, or broken, and observe any sharp edges.

3.Check the power cord:

vMake 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.

vMake sure that the power cord is the correct type.

vMake sure that the insulation is not frayed or worn.

4.Remove the cover.

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

6.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.

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

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

Guidelines for servicing electrical equipment

Observe the following guidelines when servicing electrical equipment:

vCheck the area for electrical hazards such as moist floors, nongrounded power extension cords, power surges, and missing safety grounds.
