Laser and LED SafetyGuidelines and Warnings for EX Series Switches
EXSeries switches and the XRE200 External Routing Engine are equipped with laser
transmitters,which are considered a Class 1 Laser Productby the U.S. Food and Drug
Administrationand are evaluatedas a Class1 Laser Product per EN 60825-1 requirements.
Observethe following guidelines and warnings:

General LaserSafety Guidelines
Whenworking around ports that support optical transceivers, observe the following
safetyguidelines to prevent eye injury:
•Donot look into unterminated ports or at fibers that connect tounknown sources.
•Donot examine unterminated optical ports with optical instruments.
•Avoiddirect exposure to the beam.
WARNING: Unterminatedoptical connectors can emit invisiblelaser
radiation.The lens in the human eye focuses all the laser poweron the
retina,so focusing the eye directly on a laser source—evena low-power
laser—couldpermanently damage the eye.
