The ports have a maximum operating distance of 100 meters (328 feet).

The 10/100Base-TX ports on the AT-8100S/24POE and AT-8100S/
48POE Switches support Power over Ethernet (PoE), which is a standard 
whereby DC power is provided by the switch 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 41.

The cable requirements of the ports are given in Table 7.

Refer to Table 26 on page 111 for the port pinouts of the 10/100Base-TX 
twisted pair ports.
