Isolated from strong electromagnetic fields produced by electrical devices.
•
For equipment designed to be installed in environments that are not environmentally controlled,
such as outdoor enclosures, see the product data sheet or for environmental conditions,
temperature, and humidity.
•
Establish at least 3 inches clearance on all sides for effective ventilation. Do not obstruct the air
intake vent on the front, side, or rear ventilation grills. Locate the system away from heat sources.

Make sure that your equipment is placed in an area that accommodates the power consumption and
component heat dissipation specifications.
•
Make sure that your power supplies meet the site DC power or AC power requirements of all the
network equipment.

Racks for Extreme Networks equipment must be permanently attached to the floor. Failure to
stabilize the rack can cause the rack to tip over when the equipment is removed for servicing.

Blank faceplates and cover panels are required for the following functions:
•
Preventing exposure to hazardous voltages and currents inside the equipment
•
Containing electromagnetic interference (EMI) that might disrupt other equipment
•
Directing the flow of cooling air through the equipment

Ultimate disposal of this product should be handled according to all national laws and regulations.

General Safety Precautions

Follow these guidelines:
•
Do not try to lift objects that you think are too heavy for you.
•
When you install equipment in a rack, load heavier devices in the lower half of the rack first to avoid
making the rack top-heavy.
•
Use only tools and equipment that are in perfect condition. Do not use equipment with visible
damage.
•
Route cables in a manner that prevents possible damage to the cables and avoids causing accidents,
such as tripping.
•
Do not place a monitor or other objects on top of the equipment. The chassis cover is not designed
to support weight.
•
To reduce the risk of fire, use only #26 AWG or larger telecommunications line cord. Use only copper
conductors.
•
Do not work on the system or connect or disconnect cables during periods of lightning activity.
•
This equipment must be grounded. Never defeat the ground conductor or operate the equipment in
the absence of a suitably installed ground conductor.
