Installing Power Supply Units
For the ratings and power requirements of each power supply unit, see
Appendix B, “Technical
Specifications”
or the data sheet for the power supply at
http://www.extremenetworks.com
.
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.
