Power specifications

Last Updated : Oct 17, 2023 |

You can power Avaya J100 Series IP Phones using Power over Ethernet (PoE) or an Avaya 5V DC power adapter. While using a power adapter, disable PoE on the Ethernet connection. You must purchase the power adapter separately.

Avaya J100 Series IP Phones are ENERGY STAR® compliant.

The following table provides the LLDP power measurement of the phones, adjuncts, and peripherals.
