Installation manual

•
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 copper 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 copper 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. Copper 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.
Installing Power Supply Units and Connecting Power
Check the ratings and power requirements of each power supply unit or router.
For the ratings and power requirements of each power supply unit, see Technical Specifications on
page 115 of this guide or the data sheet for the power supply at: www.extremenetworks.com
Warning
Be sure to satisfy the requirements listed in this section when you install Extreme Networks
power supplies.
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.
When you install AC power supplies:
•
Do not connect the power supply to an electrical source when the power supply is not installed in
the BlackDiamond X series; doing so would expose a hazardous energy and poses a potential shock
and fire hazard.
•
Plug power supplies only into properly grounded electrical outlets to prevent electrical shock and to
comply with international safety standards.
•
Use only power cords that are certified for use within the country of use. Do not attempt to modify
AC power cords.
•
Make sure that the voltage and frequency of your power source match the system electrical ratings
for the equipment. The building and/or power source must provide overload protection.
