Safety
The following safety warnings apply to all optical devices used in Extreme equipment, including but
not limited to SC GBICs (GBICs), SFP GBICs (mini-GBICs), XENPAKs, and XFP laser optic modules,
that are removable or directly installed in an I/O module or a chassis system.
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.
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.
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.
Extreme Networks optics are tested to work in all supported Extreme Networks switches. We recommend that all
customers use Extreme Networks optics in their Extreme Networks switches. Extreme Networks assumes no liability
for third-party optics. While Extreme Networks does not block third-party optics, we cannot ensure that all third-party
party optics operate properly in all Extreme Networks switches. The customer assumes all risks associated with using
third-party optics in Extreme Networks switches.
