•
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.
Maintenance Safety
When maintaining your equipment, follow these safety guidelines to avoid injury and damage to the
equipment.
•
Use only authorized accessories or components that are approved for use with this system. Failure
to follow these instructions may damage the equipment or violate required safety and EMC
regulations.
•
This system contains no customer serviceable components. Do not attempt to repair a chassis,
power supply, module, or other component. In the event of failure, return the defective unit to
Extreme Networks for repair or replacement, unless otherwise instructed by an Extreme Networks
representative.
•
To remove power from the system, you must unplug all power cords from wall outlets. The power
cord is the disconnect device to the main power source.
•
Disconnect all power cords before working near power supplies, unless you are instructed otherwise
by a product-specific maintenance procedure.
•
Replace a power cord immediately if it shows any signs of damage.
•
When you work with optical devices, power supplies, or other modular accessories, put on an ESD-
preventive wrist strap to reduce the risk of electronic damage to the equipment. Connect the other
end of the strap to an appropriate grounding point on the equipment rack or to an ESD jack on the
chassis if one is provided. Leave the ESD-preventive wrist strap permanently attached to the
equipment rack or chassis so that it is always available when you need to handle components that
are sensitive to ESD.
•
Install all cables in a manner that avoids strain. Use tie wraps or other strain relief devices.
Cable Routing for LAN Systems
Extreme Networks equipment meets the requirements for LAN system equipment.
LAN systems are designed only for intra-building installations; that is, cable runs between devices must
be in the same building as the connected units.
As allowed in the USA by the National Electrical Code (NEC), this equipment can be connected
between buildings if any one of the following conditions is true:
•
Cable runs between buildings are less then 140 feet (42.6 m) long.
•
Cable runs between buildings are directly buried.
