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 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, as specified in the
documentation for your BladeCenter unit type.
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 blade 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, and missing safety grounds.
vUse only approved tools and test equipment. Some hand tools have handles that
are covered with a soft material that does not provide insulation from live
electrical current.
vRegularly inspect and maintain your electrical hand tools for safe operational
condition. Do not use worn or broken tools or testers.
viii BladeCenter JS21 Types 7988 and 8844: Problem Determination and Service Guide

vDo not touch the reflective surface of a dental mirror to a live electrical circuit.
The surface is conductive and can cause personal injury or equipment damage if
it touches a live electrical circuit.
vSome rubber floor mats contain small conductive fibers to decrease electrostatic
discharge. Do not use this type of mat to protect yourself from electrical shock.
vDo not work alone under hazardous conditions or near equipment that has
hazardous voltages.
vLocate the emergency power-off (EPO) switch, disconnecting switch, or electrical
outlet so that you can turn off the power quickly in the event of an electrical
accident.
vDisconnect all power before you perform a mechanical inspection, work near
power supplies, or remove or install main units.
vBefore you work on the equipment, disconnect the power cord. If you cannot
disconnect the power cord, have the customer power-off the wall box that
supplies power to the equipment and lock the wall box in the off position.
vNever assume that power has been disconnected from a circuit. Check it to
make sure that it has been disconnected.
vIf you have to work on equipment that has exposed electrical circuits, observe
the following precautions:
– Make sure that another person who is familiar with the power-off controls is
near you and is available to turn off the power if necessary.
– When you are working with powered-on electrical equipment, use only one
hand. Keep the other hand in your pocket or behind your back to avoid
creating a complete circuit that could cause an electrical shock.
– When using a tester, set the controls correctly and use the approved probe
leads and accessories for that tester.
– Stand on a suitable rubber mat to insulate you from grounds such as metal
floor strips and equipment frames.
vUse extreme care when measuring high voltages.
vTo ensure proper grounding of components such as power supplies, pumps,
blowers, fans, and motor generators, do not service these components outside of
their normal operating locations.
vIf an electrical accident occurs, use caution, turn off the power, and send another
person to get medical aid.
