Power Over
Ethernet
The 10/100Base-TX ports on the AT-x310-26FP and AT-x310-50FP
Switches support Power over Ethernet (PoE). The ports supply DC power
to network devices over the network twisted pair cables. The switches
support PoE (IEEE 802.3af) and PoE+ (IEEE 802.3at). For background
information, refer to “Power Over Ethernet” on page 27.
