Cable Routing For Lan Systems; Installing Power Supply Units And Connecting Power - Extreme Networks BlackDiamond X8 Series Hardware Installation Manual

•
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.

Installing Power Supply Units and Connecting Power

Check the ratings and power requirements of each power supply unit or router.
