Ports 1 to 4 on the AT-IE200-6FP and AT-IE200-6GP Switches support
Power over Ethernet (PoE). With PoE, the switch can supply electrical
power to network devices over the same twisted pair cables that carry
network traffic. The feature can simplify network installation and
maintenance because it allows you to use the switch as a central power
source for other network devices.
Devices that receive their power over Ethernet cables are called powered
devices (PD). Examples of PDs include wireless access points, IP
telephones, web cams, and even other Ethernet switches. A PD
connected to a port on the switch receives both network traffic and power
over the same twisted-pair cable.
The AT-IE200-6FP and AT-IE200-6GP Switches support the following
versions of Power over Ethernet:
PoE (IEEE 802.3af)
PoE+ (802.3at)
Table 2 lists the switch ports that support PoE and the maximum power
levels.

The cable requirements for the twisted pair ports on the AT-IE200-6FP
and AT-IE200-6GP Switches for powered devices are given in Table 3 on
page 29. The cable requirements for ports connected to non-PoE devices
are given in Table 1 on page 27.
