PoE Devices
When connecting power over Ethernet (PoE) devices to a PoE switch, all connections between the PoE
device and the switch must remain within the same building and use a low-voltage power distribution
system per IEEE 802.3af.
Power Supply Requirements
Follow these recommendations when you plan power supply connections for the Summit family
switches:
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, we recommend that you plug your system into a
●
surge suppressor.
For power specifications for the Summit family switches, see
AC Power Cables
AC power input cords are not provided with Summit switches and power supplies. You can purchase
AC power cords for use in the US and Canada from Extreme Networks or from your local supplier.
Power supply cords for use outside of the United States and Canada are typically provided separately
by third-party distribution centers. Make sure that the power cord you use is certified for the country of
end use and suitable for the device.
The power cord must meet the requirements listed in
