Install Power Supply Units and Connect
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.
- Connect the system or power
supply only to a DC power source that complies with the safety extra-low voltage
(SELV) requirements in IEC 60950-based safety standards.
Note
Because building codes
vary worldwide, consult an electrical contractor to ensure proper equipment
grounding and power distribution for your specific installation and country.
Warning
Extreme Networks power supplies do not have switches for turning
the unit on and off. Disconnect all power cords to remove power from the device.
Make sure that these connections are easily accessible.
Extreme Networks alimentations n'ont pas de contact pour mettre
