Safety Information

Installing External Power Supply Units

For the ratings and power requirements of each power supply unit, see
Specifications"
WARNING!
Be sure that the requirements listed in this section are satisfied when installing all Extreme Networks power
supplies.
When you install external power supplies:
Plug power supplies only into properly grounded electrical outlets to help prevent electrical shock
●
and 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 the wall outlet is installed near the equipment and is easily accessible for quick
●
disconnect.
Make sure 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 inserting a power supply into the bay, do not use excessive force.
●
If multiple power supplies are used with a switch, connect each power supply to a different,
●
independent power source. If a single power source fails, it will affect only that power supply to
which it is connected. If all the power supplies on a single switch are connected to the same power
source, the entire switch is vulnerable to a power failure.
WARNING!
Wiring a DC power cord to your facility DC source voltage must be performed by a qualified, licensed electrician.
Extreme Networks AC external power supplies do not have switches for turning the unit on and off. Remove the wall
plug from the electrical outlet to disconnect the power from an Extreme Networks AC external power supply. Make
sure that this connection is easily accessible.
Do not connect an EPS-600LS power supply to an electrical outlet when the power supply is not installed in the
EPS-C chassis; doing so would expose a hazardous energy and poses a potential shock and fire hazard.
Do not put your hand into an open power supply bay when a power supply is not present. Empty power supply bays
require a cover plate at all times.
