PoE Devices
When connecting power over Ethernet (PoE) devices to a PoE switch, all connections
between the PoE device and the switch have to remain within the same building and you
need to use a low-voltage power distribution system per IEEE 802.3af.
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
•
different, independent power sources.
If a power source fails, it will affect only the 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, NETGEAR recommends that you plug
•
your system into a surge suppressor.
For power specifications of the power supplies, see
WARNING!
The chassis does not have a switch for turning power to the unit
on and off. For systems using an AC power supply, power to the
chassis is disconnected by removing the wall plug from the
electrical outlet.
