*Ethernet Port Wiring
The PoE switch supports one RJ-45 uplink (port 8) and seven RJ-45 ports (port 1~7 with PoE PSE)
with automatic MDI/MDI-X crossover, auto-sense for speed and duplex for 10Base-T, 100Base-TX
or 1000Base-T connection. Automatic MDI/MDI-X crossover allows you to connect to other
devices (switches, hubs, or workstations etc.), without regard to using straight-through or crossover
cabling.
Port 1 to 7 provides Power over Ethernet function that delivers DC power through the data pairs
(mode A, mode B & 8 pairs) to the PD.
The following tables describe the wiring diagram of straight-through and crossover cabling. The
crossover cables simply cross-connect the transmission lines at each end to the receive lines at the
opposite end.
