A Safety Information
WARNING!
Read the following safety information thoroughly before installing Extreme Networks products. Failure to follow this
safety information can lead to personal injury or damage to the equipment.
Only trained service personnel should perform service to Extreme Networks switches and their
components. Trained service personnel have read all related installation manuals, have the technical
training and experience necessary to be aware of the hazards to which they are exposed in performing a
task, and are aware of measures to minimize the danger to themselves or other persons.
Fiber Optic Ports—Optical Safety
The following safety warnings apply to all optical devices used in Extreme Networks equipment that
are removable or directly installed in an I/O module or chassis system. These devices include, but are
not limited to, the following devices:
● SC gigabit interface converters (GBICs)
● SFP GBICs (mini-GBICs)
● XENPAKs
● XFP laser optic modules
CAUTION
Laser optic modules become very hot after prolonged use. Take care when removing a laser optic module from the
chassis or option card. If the laser optic module is too hot to touch, disengage the laser optic module and allow it to
cool before removing it completely.
WARNING!
When working with laser optic modules, always take the following precautions to prevent exposure to hazardous
radiation:
● Never look at the transmit LED/laser through a magnifying device while it is powered on.
● Never look directly at a fiber port on the switch or at the ends of a fiber cable when they are powered on.
● Invisible laser radiation can occur when the connectors are open. Avoid direct eye exposure to the beam
when optical connections are unplugged.
● Never alter, modify, or change an optical device in any way other than suggested in this document.
