NOTE
Building codes vary worldwide; therefore, Extreme Networks strongly recommends that you consult an electrical
contractor to ensure proper equipment grounding and power distribution for your specific installation & country.
Battery Replacement and Disposal
Batteries included with Extreme products are encapsulated and must be replaced by qualified Extreme
Service personnel only. Contact your Extreme Service personnel for product replacement. Do not
attempt to replace the battery. If these instructions are disregarded and replacement of these batteries is
attempted, the following guidelines must be followed to avoid danger of explosion:
● Replace the battery with the same or equivalent battery type as recommended by the battery
manufacturer.
● Dispose of the battery in accordance with the battery manufacturer’s recommendation.
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. Such devices include but are not
limited to gigabit interface converters (GBICs), small form factor pluggable (SFP) modules (or mini-
GBICs), 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.
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.
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.
