Safety Notices
A danger notice indicates the presence of a hazard that has the potential of causing death or
serious injury. A caution notice indicates the presence of a hazard that has the potential of causing
moderate or minor personal injury.
Note: For a translation of these notices, see System Unit Safety Information, order number SA23-
2652.
Electrical Safety
Observe the following safety instructions any time you are connecting or disconnecting devices
attached to the workstation.
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 communications 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.
DANGER: To prevent electrical shock hazard, disconnect all power cables from the electrical outlet
before relocating the system.
Laser Safety Information
CAUTION: This product contains a CD-ROM and a laser module on a PCI card, which are class 1
laser products.
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.
