Selecting Power Supply Cords - Extreme Networks ExtremeSwitching SLX 9250 Hardware Installation Manual

Selecting Power Supply Cords

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.
