Guidelines for trained service technicians

This section contains information for trained service technicians.

Inspecting for unsafe conditions

Use the information in this section to help you identify potential unsafe conditions in

an IBM product that you are working on. Each IBM 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-IBM

alterations or attachment of non-IBM 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 adamaged CRT face or abulging 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, as specified in “Power

cords” on page 27.

vMake sure that the insulation is not frayed or worn.

4. Remove the cover.

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

of any non-IBM 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.

vUse only approved tools and test equipment. Some hand tools have handles that

are covered with asoft material that does not provide insulation from live

electrical currents.

vRegularly inspect and maintain your electrical hand tools for safe operational

condition. Do not use worn or broken tools or testers.
