General Safety Precautions
Follow these guidelines:
● Do not attempt 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.
● Only use 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.
Cable Routing for LAN Systems
Extreme Networks equipment meets the requirements for LAN system equipment. LAN systems are
designed for intra-building installations; that is, cable runs between devices must be in the same
building as the connected units, except under the conditions listed in the next paragraph.
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 than 140 feet long.
● Cable runs between buildings are directly buried.
● Cable runs between buildings are in an underground conduit, where a continuous metallic cable
shield or a continuous metallic conduit containing the cable is bonded to each building grounding
electrode system.
CAUTION
Failure to follow these requirements for cable routing conditions may expose the user to electrical shock
and expose the unit to damage that can cause errors.
WARNING!
The Ethernet ports of the equipment and its sub-assemblies are suitable only for intra-building connections
(within the same building) or for connections to unexposed wiring or cabling. (See the conditions listed above.) The
Ethernet ports of this equipment or its sub-assemblies must not be metallically connected to interfaces that connect
to the outside plant (OSP) or its wiring. Ethernet interfaces are designed for use only as intra-building interfaces
(described as Type 2 or Type 4 ports in GR-1089-CORE, Issue 6) and require isolation from the exposed OSP
wiring. The addition of Primary Protectors is not sufficient protection to connect these interfaces metallically to
OSP wiring.
This warning does not apply to T1/E1 ports because T1/E1 ports have built-in isolation and surge protection that
allows them to be connected to OSP wiring.
