Note: For a translation of these notices, see the System Unit Safety Information
manual, order number SA23-2652.
Rack Safety Instructions
vDo not install this unit in a rack where the internal rack ambient temperatures will
exceed 40 degrees C.
vDo 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 indirect contact with
the rack.
vCare 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 removed this unit.
vThis unit requires 3 amp. with an input of 200-240 V ac power. 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.

vAn 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.
xiv Service Guide

Electrical Safety
Observe the following safety instructions any time you are connecting or disconnecting
devices attached to the server.
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.
Before installing or removing signal cables, ensure that the power cables for
the system unit and all attached devices are unplugged.
When adding or removing any additional devices to or from the system,
ensure that the power cables for those devices are unplugged before the
signal cables are connected. If possible, disconnect all power cables from the
existing system before you add a device.
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 communication lines.
CAUTION:
This product is equipped with a three–wire power cable and plug for the user’s
safety. Use this power cable with a properly grounded electrical outlet to avoid
electrical shock.
CAUTION:
This unit has more than one power supply cord. To reduce the risk of electrical
shock, disconnect two power supply cords before servicing.
CAUTION:
Energy hazard, remove power before servicing. Disconnect two power supply
cords.
Preface xv

Laser Safety Information
The optical drive in this system unit is a laser product. The optical drive has a label that
identifies its classification. The label, located on the drive, is shown below.
The optical drive in this system unit is certified in the U.S. to conform to the
requirements of the Department of Health and Human Services 21 Code of Federal
Regulations (DHHS 21 CFR) Subchapter J for Class 1 laser products. Elsewhere, the
drive is certified to conform to the requirements of the International Electrotechnical
Commission (IEC) 825 (1st edition 1984) and CENELEC EN 60 825:1991 for Class 1
laser products.
CAUTION:
A class 3 laser is contained in the device. Do not attempt to operate the drive
while it is disassembled. Do not attempt to open the covers of the drive as it is
not serviceable and is to be replaced as a unit.
Class 1 laser products are not considered to be hazardous. The optical drive contains
internally a Class 3B gallium–arsenide laser that is nominally 0.14 milliwatts at 765 to
815 nanometers. The design incorporates a combination of enclosures, electronics, and
redundant interlocks such that there is no exposure to laser radiation above a Class 1
level during normal operation, user maintenance, or servicing conditions.

xvi Service Guide

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.
