Laser Safety Information
This system contains a laser product called the
IBM
Optical Link Card (OLC).
In
the U.S., the OLC
is
certified by
IBM
as a Class I laser product that conforms to the requirements contained
in
the Department
of Health and Human Services (DHHS) regulation
21
CFR Subchapter J. Internationally, the OLC is certi-
fied as a Class 1 laser product that conforms to the requirements contained in the International
Electrotechnical Commission (IEC) standard 825 (1984), the Verband Deutscher Elektrotechniker (VDE)
standard 0837 (1986), and the CENELEC (European Committee for Electrotechnical Standardization)
Harmonization Document HD 482
S1
(1989). The German testing institute VDE assigned IBM a certificate
of conformity to
DIN
IEC 825/VDE 0837/02.86 and CENELEC
HD
482 S1/03.88; the certificate registration
number is either 3642 or 3886 (determined by the manufacturing site).
In
addition, Statens
Provningsanstalt (Swedish National Testing Institute) tested and approved the OLC for use in Sweden as
a Class 1 laser product and assigned IBM the approval number SP LA 89:184.
The IBM OLC
is
a dual port card that internally contains two semiconductor laser diodes (one for each
port). Both of the laser diodes are of the gallium aluminum arsenide (GaAIAs) type, emitting in the wave-
length range of 770 to 800 nanometers. The discrete laser diodes are Class 3B laser products with a
rating of 5.0 milliwatts peak power. Once they are assembled into the OLC, the automatic laser control
safety system prevents laser emissions from being more than Class 1 limits during both operation and
service. There are no user maintenance operations or adjustments to
be
performed
on
the
IBM
OLC.
Class 1 laser products are not considered to
be
hazardous.
The IBM OLC
is
designed and certified for use in applications with point-to-point optical links only. Use of
the product with multiple input or multiple output links (for example, star couplers) is not compatible with its
design and function.
In
addition, the IBM OLC must only be connected to another IBM OLC or a compat-
ible laser product that contains the open fiber link detection and laser control safety system used
in
the
IBM OLC. These are requirements for correct operation of the IBM OLC in any optical fiber communica-
tion system. Failure to follow these restrictions may result in the system not operating correctly and points
of access that emit laser radiation above the Class 1 limit specified by IEC 825 (1984).

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
Note: This equipment has been tested and found to comply with the limits for a Class B digital device,
pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against
harmful interference
in
a residential installation. This equipment generates, uses, and can radiate radio
frequency energy and, if not installed and used in accordance with the instructions, may cause harmful
interference to radio communications. However, there is no guarantee that interference will not occur
in
a
particular installation.
If
this equipment does cause harmful interference to radio or television reception,
which 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:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
• Consult
an
IBM
authorized dealer or service representative for help.
