I need to know if the expansion module 7915 need a power supply adapter to work or if this take the energy from the aux cable connected to the IP phone?

Hello,
Table 7. Power Requirements
If the phone is powered via POE, you need a power cube for the sidecar. If the phone is powered via a power cube, you would only need another power cube for a second sidecar.
