CAUTION: This product might contain one or more of the following devices: CD-ROM drive, DVDROM
drive, DVD-RAM drive, or laser module, which are Class 1 laser products. Note the following
information:

Do not remove the covers. Removing the covers of the laser product could result in exposure to
hazardous laser radiation. There are no serviceable parts inside the device.

Use of the controls or adjustments or performance of procedures other than those specified
herein might result in hazardous radiation exposure.
(C026)
IBM® servers can use I/O cards or features that are fiber-optic based and that utilize lasers or LEDs.
Laser compliance
IBM servers may be installed inside or outside of an IT equipment rack.
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 IEC 60825 as a class 1 laser
product. Consult the label on each part for laser certification numbers and approval information.
CAUTION:
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. Although shining light into one end and looking into the other end of a
disconnected optical fiber to verify the continuity of optic fibers many not injure the eye, this procedure
is potentially dangerous. Therefore, verifying the continuity of optical fibers by shining light into one end
and looking at the other end is not recommended. To verify continuity of a fiber optic cable, use an
optical light source and power meter. (C027)
CAUTION:
This product contains a Class 1M laser. Do not view directly with optical instruments. (C028)
CAUTION:
Some laser products contain an embedded Class 3A or Class 3B laser diode. Note the following
information: laser radiation when open. Do not stare into the beam, do not view directly with optical
instruments, and avoid direct exposure to the beam. (C030)
