Polarity reversing cable for pre-standard PoE Cisco phones
The WS-Cisco reverses the voltage for Cambium, Canopy, and pre-standard phones when used with the WS-POE-8 and WS-PoE-12 products.
It reverses the + and – in the 2.1 mm dc connector, when used with our 48v power supply to power any of these phones:
