This device has 2 DC inputs, 2 low loss diodes, and a DC output. As long as either power supply input has power, there will be power on the output.
All 3 DC sockets are 2.1mm x 5.5mm
One 2.1mm to 2.1mm 30 cm long jumper cable is included.
Note: our WS-POE-16 has this diode function built in.
- WS-GPOE-12 in Mode B applications
- Any PoE Switch with external power
If powering 802.3af devices, these products include dual input power jacks that serve the same function redundant power
This is possible because power is on all 4 pairs of the ethernet cable, and 802.3af devices are required to allow power on either pair.
