Selecting Power Supply Cords - Extreme Networks Summit X150 Series Hardware Installation Manual

Use only power cords that are certified for use within the country of use. Do not attempt to modify
●
AC power cords.
Make sure that the voltage and frequency of your power outlet match the system electrical ratings
●
for the equipment. The building and/or power source must provide overload protection.
Use a surge suppressor, line conditioner, or uninterruptible power supply to protect the system from
●
momentary increases or decreases in electrical power.
When multiple power supplies are used with a system, connect each power supply to a different,
●
independent over-current protection device, such as a circuit breaker. If a single power source fails, it
will affect only that power supply to which it is connected. See the data sheet of the power supply
for proper sizing of the circuit breaker.
Extreme Networks AC power supplies do not have switches for turning the unit on and off. Remove
●
all wall plugs from the electrical outlets to disconnect the power. Make sure that these connections
are easily accessible.
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 off. 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.

Selecting Power Supply Cords

Extreme Networks does not include power input cords in the product box. You can purchase a power
