•
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 may 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
Be sure to satisfy the requirements listed in this section when you install Extreme Networks power
supplies or connect power.
Check the ratings and power requirements of each power supply unit or router.
For more information, see
Technical Specifications
on page 91 or the data sheet for the equipment at:

.
When you install any power supply:
•
Do not use excessive force when you insert a power supply into the bay.
•
Do not attempt to open the power supply enclosure for any reason; the power supply does not
contain user-serviceable parts. In the event of failure, return the defective power supply to Extreme
Networks for repair or replacement.
•
Do not put your hand into an open power supply bay when a power supply is not present. An empty
power supply bay requires a cover at all times.
•
Before you work on equipment that is connected to power lines, remove all jewelry, including
watches. Metal objects heat up when they are connected to power and ground and can cause
serious burns or weld the metal object to the terminals.
•
An electrical arc can occur when you connect or disconnect the power with power applied. This
could cause an explosion in hazardous area installations. Be sure that power is removed from the
device.
•
When you install or replace equipment, always make the ground connection first and disconnect the
ground connection last.
