The DIN-4P connector on the rear panel also used for power input, you can use an AC/DC adapter
with DIN-4P connector directly, recommends adaptor MS-180-56-DIN (OPTION)
The input voltage must be in the range of 44 to 57VDC if running for 802.3af operation.
The input voltage must be in the range of 50 to 57VDC if running for 802.3at operation.
If the model is not powered with the above designated input voltage, it will only function as an
Ethernet switch without PoE output.

*Ethernet Port Wiring
The PoE switch supports one RJ-45 uplink (port 5 with PoE PD) and four RJ-45 ports (port 1~4
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 4 provides Power over Ethernet function that delivers DC power through the data pairs C
& D (pin 4,5 and pin 7,8) (mode B) to the PD.
Port 5 provides Power Device function that receive power from 4 pairs or 2 pairs Ethernet cable.
The following tables describe 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.
