The Cisco 8832 PoE Injector is used with the Cisco 8832 IP Conference Phone in PoE deployments.
NOTE: The title of this product, 'Cisco 8832 PoE Injector', is a misnomer. It does not inject power to your Cisco 8832 unit. It passes both power and data only when your Cisco 8832 is connected to a Power over Ethernet (PoE) enabled switch. If your Cisco 8832 is connected to a standard non-PoE switch, then you will also have to add a PoE Injector to power your unit. See PoE injector in accessory section below.
