Safety and Environmental Notices

Danger Notices

A danger notice calls attention to a situation that is potentially lethal or extremely

hazardous to people.

Use the following danger notices throughout this book.

DANGER

To prevent a possible electrical shock from touching two surfaces with

different electrical grounds, use one hand, when possible, to connect or

disconnect signal cables. (RSFTD004)

DANGER

Dangerous voltage being measured. (RSFTD005)

vi 7206 Model 220 Service Guide

DANGER

Up to 240 V ac is present at the power module connectors when the main

power cord is connected to a power source. (RSFTD010)

DANGER

An electrical outlet that is not correctly wired could place hazardous voltage

on metal parts of the system or the products that attach to the system. It is the

customer’s responsibility to ensure that the outlet is correctly wired and

grounded to prevent an electrical shock. (RSFTD201)

DANGER

To prevent a possible electrical shock when adding or removing any devices

to or from the system, ensure that the power cords for those devices are

unplugged before the signal cables are connected or disconnected. If possible,

disconnect all power cords from the existing system before you add or

remove a device. (RSFTD203)

DANGER

To prevent a possible electrical shock when installing the device, ensure that

the power cord for that device is unplugged before installing signal cables.

(RSFTD204)

DANGER

Do not attempt to open the covers of the power supply. Power supplies are

not serviceable and are to be replaced as a unit. (RSFTD217)

Caution Notices

A caution notice calls attention to a situation that is potentially hazardous to

people because of some existing condition.

Use the following caution notices throughout this book.

Attention Notices

An attention notice indicates the possibility of damage to a program, device,

system, or data.

Product Recycling and Disposal

Components of the system, such as structural parts and circuit cards, can be

recycled where recycling facilities exist. IBM does not currently collect and recycle

used IBM products from customers in the United States other than those products

that are involved in trade-in programs. Companies are available to disassemble,

reutilize, recycle, or dispose of electronic products. Contact an IBM account

representative for more information.

The system unit contains batteries and circuit boards with lead solder. Before you

dispose of this unit, these batteries and circuit boards must be removed and

discarded according to local regulations or recycled where facilities exist. This book

contains specific information on each battery type where applicable.

Notices vii

Battery Return Program

In the United States, IBM has established a collection process for reuse, recycling,

or proper disposal of used IBM batteries and battery packs. For information on

proper disposal of the batteries in this unit, please contact IBM at 1-800-426-4333.

Please have the IBM part number that is listed on the battery available when you

make your call. For information on battery disposal outside the United States,

contact your local waste disposal facility.

Environmental Design

The environmental efforts that have gone into the design of the system signify

IBM’s commitment to improve the quality of its products and processes. Some of

these accomplishments include the elimination of the use of Class I

ozone-depleting chemicals in the manufacturing process, reductions in

manufacturing wastes, and increased product energy efficiency. For more

information, contact an IBM account representative.
