Avaya Vantage™ can receive power from the following sources:
802.3af PoE (Class 3)
802.3at PoE (Class 4)
48 Vdc power supply
If you use the 802.3at networking switch or the power adapter, Avaya Vantage™ USB port delivers up to 500mA. If you use the 802.3af networking switch, Avaya Vantage™ USB port delivers up to 100mA.
You can use a 48-volt, 30-watt power adapter to power Avaya Vantage™ in the following conditions:
You are using Wi-Fi to connect to the network instead of using a PoE networking switch port.
The networking switch port does not support the 802.3af or 802.3at PoE specification.
The device requires more power than a 802.3af PoE networking switch port can provide, and 802.3at PoE port is unavailable. For example, a USB device that requires more than 0.5 watts is connected to Avaya Vantage™ and only 802.3af PoE ports are available. In this case, you must connect Avaya Vantage™ to a power adapter.
You must purchase the power adapter separately.
If Avaya Vantage™ is connected to both a 48 Vdc power supply and a PoE networking switch port and you disconnect one of the power sources, then the following occurs:
If you disconnect the power adapter, Avaya Vantage™ reboots. If the networking switch supports the 802.3at or 802.3af specification, Avaya Vantage™ continues to work after the reboot.
If you disconnect the networking switch, Avaya Vantage™ continues to work without a reboot.
If Avaya Vantage™ is already connected to a PoE networking switch and you connect the power adapter to the device, Avaya Vantage™ continues to work without a reboot.
