*Power wiring
The PoE switch accepts input voltage from terminal block P3 or DIN 4P connector (rear panel) or
RJ45 (port 8).
For PSE-SW8S,
If power input from terminal block P3, the input voltage must be in the range of 12 to 57 VDC. The
output current is 1A/port (continuously), it can up to 2A/port maximum for temporary, but total
output power MUST limited at 7A maximum. If power input from port 8, the input current is
limited at 2A maximum, the output is 0.25A/port.
For PSE-SW8D
The input voltage must be in the range of 44 to 57VDC if running for 802.3af operation or 50 to
57VDC if running for 802.3at operation. If the model is not powered within designated voltage, it
will only function as an Ethernet switch without PoE output.
If power input from terminal block P3, and if output power to 802.3af devices, the output current is
0.35A/port, if output power to 802.3at devices, the output power is 0.625A/port maximum.
If power input from port 8, the input current is limited at 2A maximum, the output is 0.25A/port.
The PoE PSE ports (port 1-7) will deliver DC power over the spare pairs as the connection:
* TX on lines 1 and 2
* RX on lines 3 and 6
* V+ on line 4 and 5
* V- on line 7 and 8
