Fiber Optic Ports and 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, gigabit interface converters (GBICs); SFP optical modules
(mini-GBICs) and SFP+ optical modules; QSFP+ optical modules; XENPAK transceivers; and
XFP laser optic modules.
Warning
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.
When working with laser optic modules, always take the
precautions listed below 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.
