Maximum
Distance
The ports have a maximum operating distance of 100 meters (328 feet).
Power Over
Ethernet
The 10/100Base-TX ports on the AT-FS970M/8PS, AT-FS970M/8PS-E,
AT-FS970M/24PS and AT-FS970M/48PS 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 39.
