Installing Power Supply Units And Connecting Power - Extreme Networks 8720 Hardware Installation Manual

Installing Power Supply Units and Connecting Power

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
For the ratings and power input requirements of each power supply unit, see "Technical
Specifications" 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 or connect power.
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.
•
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.
When you install DC power supplies or connect DC power:
•
Extreme Networks DC power supplies do not have switches for turning the unit
on and off. Make sure that the DC circuit is de-energized before connecting or
disconnecting the DC power cord at the DC input power socket.
