Selecting Power Supply Cords
E4G Series Routers Hardware Installation Guide

When you install AC power supplies:
●
For switches with field-replaceable power supplies, do not connect the power supply to an electrical
source when the power supply is not installed in the switch; doing so would expose a hazardous
energy and poses a potential shock and fire hazard.
●
Plug power supplies only into properly grounded electrical outlets to help prevent electrical shock
and to comply with international safety standards.
●
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 outlet 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 and DC-powered devices 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 power input 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
Building codes vary worldwide; therefore, 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 AC power input cords in the product box. You can purchase a
power cord for your product and for your specific country from your local Extreme Networks Channel
Account Manager or Sales Manager, or you can purchase a cord from your local supplier. Requirements
for the power cord are listed in
Appendix B of this guide.
