Do IP phones require external power supplies when connected to AR series routers

2

When connected to the AR1220V, AR1220W, AR1220VW, IP phones without external power supplies must be connected to FE4 through FE7 interfaces on the main control board. The Routers must be connected to external power over Ethernet (PoE) power supplies.When connected to other AR Series Routers, IP phones must be equipped with external power supplies.

Is the CT license required when the IP phone connects to the AR
The CT license is used to implement call transfer over a trunk. That is, calls received over one trunk are forwarded over another trunk. The CT license is not required when the IP phone connects to the AR.

Does the VPC600/VPC620 need to connect to an external power cable if the camera is to be connected to a TE series endpoint?
The VPC600/VPC620 camera can connect to an external power cable after the camera is connected to a TE series endpoint. After the connection, the external power module supplies power for the VPC600/VPC620. The HD-VI cable does not supply power to the camera any more.

Do I need to connect the external power supply to the VPC600 camera after its HD-VI port is connected to the TE40?
The VPC600/VPC620 camera uses the HD-VI video port that supports serial port control signals, transparent transmission of infrared signals, and 12 V power input. After the camera is connected to a TE endpoint, the camera is powered and does not require the external power. However, you can also connect the external power supply to the camera, which will not damage the camera. In this case, the camera is powered by the external power supply and the HD-VI cable stop powering the camera.

Do I need to connect an external power cable to the VPC600 or VPC620 after I connect it to a TE series endpoint?
An external power cable can be connected to the VPC600 or VPC620. After the connection, the external power supply is used and the HD-VI cable does not supply power to the camera.

Can the AR router connected to a PoE power supply provide power for itself
The AR provides PoE power for downstream terminals. The AR equipped with the 100 W AC power module provides power for PDs connected to FE interfaces. The PDs include IP phones, APs, and cameras. PoE models: AR207V-P and AR201VW-P; interfaces: Ethernet0/0/0 to Ethernet0/0/7 PoE model: AR151W-P; interfaces: Ethernet0/0/0 to Ethernet0/0/4 PoE models: AR1220V, AR1220W, and AR1220VW; interfaces: Ethernet0/0/4 to Ethernet0/0/7 All GE electrical interfaces on the 4ES2GP-S card support PoE, but the AR must be equipped with the 100 W AC PoE module.
