The most cost-effective option would be to use our Power Injector (011124), plugging one end into the network source (non-PoE hub) and one end into the device.
Alternatively, for products with the +48VDC power jack like the Paging Server (011146) and Paging Adapter (011233) we recommend using the CISCO 48V supply CP-PWR-CUBE-4.

number CP-PWR-CUBE-4) and the appropriate power cord (Power
requirements for the power adapter: 100-240 VAC, 50-60 Hz, 0.5 A).
