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:

v Electrical hazards, especially primary power. Primary voltage on the frame can

cause serious or fatal electrical shock.

v Explosive hazards, such as a damaged CRT face or a bulging or leaking

capacitor.

v Mechanical hazards, such as loose or missing hardware.

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:

v 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.

v Make sure that the power cord is the correct type, as specified in “Power

cords” on page 92.

v Make sure that the insulation is not frayed or worn.

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.

viii System x3400 Types 7973, 7974, 7975, and 7976: Problem Determination and Service Guide

Guidelines for servicing electrical equipment

Observe the following guidelines when servicing electrical equipment:

v Check the area for electrical hazards such as moist floors, nongrounded power

extension cords, power surges, and missing safety grounds.

v Use 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 currents.

v Regularly inspect and maintain your electrical hand tools for safe operational

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

v Do 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.

v Some rubber floor mats contain small conductive fibers to decrease electrostatic

discharge. Do not use this type of mat to protect yourself from electrical shock.

v Do not work alone under hazardous conditions or near equipment that has

hazardous voltages.

v Locate 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.

v Disconnect all power before you perform a mechanical inspection, work near

power supplies, or remove or install main units.

v Before 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.

v Never assume that power has been disconnected from a circuit. Check it to

make sure that it has been disconnected.

v If 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.

Use extreme care when measuring high voltages.

v To 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.

v If an electrical accident occurs, use caution, turn off the power, and send another

person to get medical aid.

Safety statements

Important:

Each caution and danger statement in this documentation begins with a number. This number is used to cross reference an English-language caution or danger statement with translated versions of the caution or danger statement in the Safety

Information document.

For example, if a caution statement begins with a number 1, translations for that caution statement appear in the Safety Information document under statement 1.

Be sure to read all caution and danger statements in this documentation before performing the instructions. Read any additional safety information that comes with your server or optional device before you install the device.

Notes:

1. Power consumption and heat output vary depending on the number and type of optional features installed and the power-management optional features in use.

2. These levels were measured in controlled acoustical environments according to the procedures specified by the American National Standards Institute (ANSI) S12.10 and ISO 7779 and are reported in accordance with ISO 9296. Actual sound-pressure levels in a given location might exceed the average values stated because of room reflections and other nearby noise sources. The declared sound-power levels indicate an upper limit, below which a large number of computers will operate.

Power-on LED

When this LED is lit, it indicates that the server is turned on. When this LED is off, it indicates that ac power is not present, or the power supply or the LED itself has failed.

Note: If this LED is off, it does not mean that there is no electrical power in

the server. The LED might be burned out. To remove all electrical power from the server, you must disconnect the power cords from the electrical outlets.

Power-control

button

Press this button to turn the server on and off manually.

Hard disk drive activity LED

When this LED is flashing, it indicates that a hard disk drive is in use.

System-error LED

When this amber LED is lit, it indicates that a system error has occurred. An LED on the system board might also be lit to help isolate the error. See Chapter 2, “Diagnostics,” on page 17 for additional information.

USB connectors

Connect USB devices to these connectors.

Chapter 1. Introduction 7

CD or DVD-eject button

Press this button to release a CD from the CD drive or a DVD from the DVD drive.

CD or DVD drive activity LED

When this LED is lit, it indicates that the CD drive or DVD drive is in use.

Ethernet transmit/receive activity LED

This LED is on the Ethernet connector on the rear of the server. When this LED is lit, it indicates that there is activity between the server and the network.

Ethernet link status LED

This LED is on the Ethernet connector on the rear of the server. When this LED is lit, it indicates that there is an active connection on the Ethernet port.

Hot-swap hard disk drive activity LED (some models)

On some server models, each hot-swap drive has a hard disk drive activity LED. When this green LED is flashing, it indicates that the drive is in use.

When the drive is removed, this LED also is visible on the SAS backplane, next to the drive connector. The backplane is the printed circuit board behind drive bays 4 through 11.

Hot-swap hard disk drive status LED (some models)

On some server models, each hot-swap hard disk drive has an amber status LED. If this amber status LED for a drive is lit, it indicates that the associated hard disk drive has failed.

If an optional ServeRAID™ adapter is installed in the server and the LED flashes slowly (one flash per second), the drive is being rebuilt. If the LED flashes rapidly (three flashes per second), the adapter is identifying the drive.

When the drive is removed, this LED also is visible on the SAS/SATA backplane, below the hot-swap hard disk drive activity LED.
