Power Supply Requirements

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 specifications.
•
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 specifications for your equipment, see "Technical Specifications."

Power Cord Requirements

Most ExtremeSwitching switches do not ship with power cords. Visit
www.extremenetworks.com/product/powercords/
purchasing the correct power cords for use with specific Extreme Networks equipment.
The web page provides specifications 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.
