Avaya B100 PSU for B-Range Conference Phone
The Avaya B100 PSU is a spare Power Supply Unit for the Avaya B100 Series of conference phones. Although the analogue models are sold with a PSU, making this a replacement for damaged goods, the PoE models are not supplied with a PSU. So if you do not have PoE on your network, you will need to buy this Power Supply Unit.
