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

The 10/100Base-TX ports on the AT-8100S/24POE Switch supports 
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 switch supports PoE (IEEE 802.3af) and PoE+ (IEEE 
802.3at). For background information, refer to “Power Over Ethernet” on 
page 35. 

The cable requirements of the ports are given in Table 6. 

Refer to Table 25 on page 134 for the port pinouts of the 10/100Base-TX 
ports.
