For PoE (PSE) operation, the input voltage must be in the range of 12 to 36 VDC. Otherwise, the
switch will function only as an Ethernet switch but will not provide any PoE power output. For PoE
operation, make sure your power supply is rated for at least 75 Watts for 4x 802.3af PoE port, or
150W for 4x 802.3at PoE port, plus some overhead for the switch.

*Ethernet Port Wiring
The PoE Switch supports Port 1 to Port 4 with automatic MDI/MDI-X crossover, autosense of the
speed and duplex for 10Base-T or 100Base-TX connections. 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 port 4 also provides Power over Ethernet function which delivers DC48V power through
the spare pairs (pair 4,5 and pair7,8) to the PD.
The following tables depict the wiring diagram of straight-through and crossover cabling. The
crossover cables simply cross-connect the transmit lines at each end to the receive lines at the
opposite end.
