10/100BASE-TX Ports Definition
2.2.1 Data Input Ports
The Midspan has 6, 12 or 24 x 10/100Base-T Data In ports, located on
the PoE rear panel (Figure 2-1), configured in a non-crossover manner
(straight-wired).
These ports are located on the PoE's rear panel designed to carry
Ethernet data only (Tx/Rx) over the standard 2-wire pairs (pins 1/2 and
3/6) and are typically connected to an existing Ethernet switch.
2.2.2 Data & Power Output Ports
The Midspan has 6, 12 or 24 x 10/100Base-T Data & Power Out ports,
located on the front panel (Figure 2-2). These ports are configured in a
non-crossover manner (straight-wired) and are designed to carry Ethernet
data over the standard 2-wire pairs (pins 1/2 and 3/6) and DC power over
the spare pairs (pins 4/5 and 7/8). Each output port corresponds to an
opposite input port located on the PoE rear panel..
The Power over Ethernet Midspan is not a repeater. As such, the maximum distance from
the Ethernet switch must not exceed 100 meters (328 ft). As specified in the IEEE 802.3
standard, the Power over Ethernet Midspan is guaranteed to work up to this distance.
