Extreme Networks ExtremeSwitching 5320 Series User Manual

Power Supply Requirements
Follow these recommendations when you plan power supply connections for your
equipment:
• Place the equipment in an area that accommodates the power consumption and
component heat dissipation specications.
• Be sure that your power supply meets the site DC power or AC power requirements
of the network equipment.
• When you connect power to installed equipment, do not make this connection
through an extension cord or power strip.
• If your switch includes more than one power supply, connect each power supply to a
different, independent power source.
If a power source fails, it will affect only the switch power supply to which it is
connected. If all switch power supplies are connected to a single power source, the
entire switch is vulnerable to a power source failure.
• In regions that are susceptible to electrical storms, the best practice is to plug your
system into a surge suppressor.
For detailed power specications for your equipment, see "Technical Specications."
Power Cord Requirements
Most ExtremeSwitching switches do not ship with power cords. Visit
www.extremenetworks.com/product/powercords/ for information on selecting and
purchasing the correct power cords for use with specic Extreme Networks equipment.
The web page provides specications for power cords in each country so that you can
purchase cords locally.
UPS (Uninterruptible Power Supply) Requirements
A UPS (uninterruptible power supply) is a device that sits between a power supply
(such as a wall outlet) and a device (such as a switch) to prevent outages, sags, surges,
and bad harmonics from adversely affecting the performance of the device.
A UPS traditionally can perform the following functions:
• Absorb relatively small power surges.
• Smooth out noisy power sources.
• Continue to provide power to equipment during line sags.
• Provide power for a period of time after a blackout has occurred.
In addition, some UPS devices or UPS-plus-software combinations provide the
following functions:
• Automatically shut down equipment during long power outages.
• Monitor and log power supply status.
• Display the voltage (current draw) of the equipment.
• Restart equipment after a long power outage.
