Safety and Regulatory Information
•
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 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.
Select Power Supply Cords
A power cord is not included in the product box.

Note
This equipment is not intended to be directly powered by power distribution systems where
phase-phase voltages exceed 240 VAC (2P+PE), such as those used in Norway, France, and
other countries. For these applications, use a transformer to step down the voltage to <
240 VAC from phase-phase, or make a connection to a (P+N+PE) power distribution where
voltages do not exceed 240 VAC.
All installations should confirm that the product is reliably grounded according to the
country's local electrical codes.
