Installation Guide

When you install DC power supplies or connect DC power:
• Making the connection to your facility DC source voltage must be performed by a qualified, licensed
electrician.
• Extreme Networks DC power supplies do not have switches for turning the unit on and o. Make
sure that the DC circuit is de-energized before connecting or disconnecting the DC power cord at
the DC input power socket.
• Do not connect a DC power supply to the DC source power when the power supply is not installed in
the chassis; doing so would expose a hazardous energy and poses a potential shock and fire hazard.
• 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.
• DC-powered equipment must be installed in a restricted-access area to ensure that only trained and
qualified service personnel have access to the equipment. A restricted-access area can be entered
only through the use of a special tool, lock and key, or other means of security.
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.
