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
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)
vi 7212 Storage Device Enclosure Service Guide

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.
CAUTION:
Ensure that all rack-mounted units are fastened in the rack frame. Do not extend
or exchange any rack-mounted units when the stabilizer is not installed.
(RSFTC222)
CAUTION:
When the unit is extended, its weight can turn over a rack that is not steady.
Before you pull the unit out of the rack, ensure that a rack stabilizer is attached
to the bottom front of the rack.
Do not pull out more than one unit at a time. The rack can turn over if you pull
out more than one unit at a time. (RSFTC224)
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
Notices vii

discarded according to local regulations or recycled where facilities exist. This book
contains specific information on each battery type where applicable.
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.
Electronic Emission Notices
The following Statement applies to this IBM product. The statement for other IBM
products intended for use with this product will appear in their accompanying
manuals.
Federal Communications Commission (FCC) Statement

can be determined by turning the equipment off and on, the user is encouraged to
try to correct the interference by one or more of the following measures:
v Reorient or relocate the receiving antenna.
v Increase the separation between the equipment and receiver.
v Connect the equipment into an outlet on a circuit different from that to which
the receiver is connected.
v Consult an IBM authorized dealer or service representative for help.
Properly
shielded and grounded cables and connectors must be used in order to
meet FCC emission limits. Proper cables and connectors are available from IBM
authorized dealers. IBM is not responsible for any radio or television interference
caused by using other than recommended cables or connectors or by unauthorized
changes or modifications to this equipment. Unauthorized changes or
modifications could void the user’s authority to operate the equipment.
This device complies with Part 15 of the FCC Rules. Operation is subject to the
following two conditions: (1) this device may not cause harmful interferences, and
(2) this device must accept any interferences received, including interference that
may cause undesired operation.
