Safety Notices
A danger notice indicates the presence of a hazard that has the potential of causing death or serious
personal injury. Danger notices appear on the following pages:

For a translation of the safety notices contained in this book, see the System Unit Safety Information,
order number SA23-2652.
Rack Safety Instructions
v Do not install this unit in a rack where the internal rack ambient temperatures will exceed 35 degrees C.
v Do not install this unit in a rack where the air flow is compromised. Any side, front or back of the unit
used for air flow through the unit must not be in direct contact with the rack.
v Care should be taken to ensure that a hazardous condition is not created due to uneven mechanical
loading when installing this unit in a rack. If the rack has a stabilizer it must be firmly attached before
installing or removing this unit.
v Consideration should be given to the connection of the equipment to the supply circuit so that
overloading of circuits does not compromise the supply wiring or overcurrent protection. To provide the
correct power connection to the rack, refer to the rating labels located on the equipment in the rack to
determine the total power requirement for the supply circuit.
v An electrical outlet that is not correctly wired could place hazardous voltage on the metal parts of the
system or the devices that attach to the system. It is the responsibility of the customer to ensure that
the outlet is correctly wired and grounded to prevent an electrical shock.
Electrical and Mechanical Safety
Observe the following safety instructions any time you are connecting or disconnecting devices attached to
the system.
DANGER
An
electrical outlet that is not correctly wired could place hazardous voltage on metal parts of
the system or the devices that attach to the system. It is the responsibility of the customer to
ensure that the outlet is correctly wired and grounded to prevent an electrical shock.
Use one hand, when possible, to connect or disconnect signal cables to prevent a possible
shock from touching two surfaces with different electrical potentials.
During an electrical storm, do not connect cables for display stations, printers, telephones, or
station protectors for communications lines.

CAUTION:
This product is equipped with a four-wire (three-phase and ground) power cable for the user’s
safety. Use this power cable with a properly grounded electrical outlet to avoid electrical shock.
C27
DANGER
To prevent electrical shock hazard, disconnect all power cables from the electrical outlet before
relocating the system.
D01
CAUTION:
Metal edges might be sharp.

Laser Safety Information
CAUTION:
This product may contain a CD-ROM, DVD-ROM, or laser module on a PCI card, which are class 1
laser products.
C30
Laser Compliance
All lasers are certified in the U.S. to conform to the requirements of DHHS 21 CFR Subchapter J for class
1 laser products. Outside the U.S., they are certified to be in compliance with the IEC 825 (first edition
1984) as a class 1 laser product. Consult the label on each part for laser certification numbers and
approval information.
CAUTION:
All IBM laser modules are designed so that there is never any human access to laser radiation
above a class 1 level during normal operation, user maintenance, or prescribed service conditions.
Data processing environments can contain equipment transmitting on system links with laser
modules that operate at greater than class 1 power levels. For this reason, never look into the end
of an optical fiber cable or open receptacle. Only trained service personnel should perform the
inspection or repair of optical fiber cable assemblies and receptacles.

Data Integrity and Verification
IBM computer systems contain mechanisms designed to reduce the possibility of undetected data corruption
or loss. This risk, however, cannot be eliminated. Users who experience unplanned outages, system failures,
power fluctuations or outages, or component failures must verify the accuracy of operations performed and
data saved or transmitted by the system at or near the time of the outage or failure. In addition, users must
establish procedures to ensure that there is independent data verification before relying on such data in
sensitive or critical operations. Users should periodically check the IBM support websites for updated
information and fixes applicable to the system and related software.

Highlighting
The following highlighting conventions are used in this book:
Bold Identifies commands, subroutines, keywords, files, structures, directories, and other items
whose names are predefined by the system. Also identifies graphical objects such as buttons,
labels, and icons that the user selects.
Italics Identifies parameters whose actual names or values are to be supplied by the user.
Monospace Identifies examples of specific data values, examples of text similar to what you might see
displayed, examples of portions of program code similar to what you might write as a
programmer, messages from the system, or information you should actually type.
