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.
