Select Power Supply Cords - Extreme Networks 7720 Installation Manual

Safety Information
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, Extreme Networks strongly
recommends that you 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 l'appareil
sous et hors tension. Débranchez tous les cordons d'alimentation pour couper
l'alimentation de l'appareil. Assurez-vous que ces connexions sont facilement
accessibles.
