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)
CAUTION: To reduce the risk of electric shock or energy hazards:
This equipment must be installed by trained service personnel in a restricted-access
location, as defined by the NEC, IEC 60950 and IEC 62368, The Standard for Safety of
Information Technology Equipment.
