10/100BASE-TX Data Input Ports, Lower 24 Ports
The PowerDsine 24PT In-Line Power Unit has 24 10 Base-T / 100 Base-Tx data input ports
configured as Media Dependant Interface (MDI) (non-crossover). These ports are designed to
carry Ethernet Data only (Tx/Rx) over the standard 2-wire pairs (RJ-45 pins 1,2 and 3,6).
10/100BASE-TX Data & Power Output Ports, Upper 24 Ports
The PowerDsine 24PT In-Line Power Unit has 24 Data & Power ports configured as MDI
(non-crossover). These ports are designed to carry Ethernet Data over the standard 2-wire
pairs (RJ-45 pins 1/2 and 3/6) and DC Power Source over the spare wire pair (RJ-45 pins 4/5
and 7/8).
According to the IEEE 802.3 standard, the maximum allowable distance between two Ethernet
links is 100m (328ft). The PowerDsine 24PT In-Line Power Unit is IEEE 802.3af Draft 3.0
compliant.
Console Port
The console port (DB-9 connector) allows one to connect a terminal and perform local
out-of-band management. The console port uses a standard null modem cable and is set to
19,200-baud, 8 data bits, no parity, and 1 stop bit.
Port LEDs
One bicolor LED (green and orange) per port provides port status. Green indicates that the
terminal unit has been identified as, “Power over LAN Enabled” and is active and receiving
power. Orange or blinking indicates a fault or other condition. See User Guide for more
information.
