Safety Information

Installing Power Supply Units

For the ratings and power requirements of each power supply unit, see
Specifications"
WARNING!
Be sure that the following requirements are satisfied when installing all Extreme Networks power supplies.
Make sure to satisfy the following requirements:
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.
The wall outlet must be installed near the equipment and be easily accessible for quick disconnect.
●
Make sure the voltage and frequency of your power outlet match the equipment's system's electrical
●
ratings. 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.
For hot-swappable power supplies, do not slam the PSU into the bay.
●
If multiple power supplies are used in 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!
Extreme Networks 325 W DC PSUs 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 socket on the Extreme
Networks 325 W DC PSU.
Wiring the 325 W DC PSU DC power cord to your facility DC source voltage must be performed by a qualified,
licensed electrician.
Extreme Networks 325 W AC PSUs do not have switches for turning the unit on and off. Remove the wall plug from
the electrical outlet to disconnect the power to an Extreme Networks 325 W AC PSU. Make sure that this
connection is easily accessible.
Do not connect the power supply into an electrical outlet when the power supply is outside the 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.
