Equipment Warning Label - Nortel SONET AccessNode Manual

1-6 Overview of site testing
Although Nortel S/DMS optical products have a Class I certification,
hazardous exposure to laser radiation could occur when fibers that
interconnect system components are disconnected or broken. Certain
procedures carried out during testing require the handling of optical fibers
without dust caps, and therefore increase the risk of exposure. Exposure to
either visible or invisible laser light could cause eye damage under certain
conditions.
The caution label at the right appears on the
optical interface card, near the optical connector,
and should be complied with.

Equipment warning label

The equipment label is located in the top left corner of the back cover. It reads
as follows:

equipment rooms, equipment closets, or the like) in accordance
with articles 110-16, 110-17, and 110-18 of the National
Electrical Code, ANSI/NFPA No. 70.
