Power Requirements for VVX Expansion Modules
Due to the additional power required for Expansion Module(s), the Power over Ethernet (PoE) that powers your
phone may not be sufficient to power multiple expansion modules and the USB port(s) on the phone (VVX500/
VVX600 only). Please refer to the table below to determine whether you need an additional 48V power supply
unit to accommodate your configuration.
Note: The USB port on the rear of the VVX500 and VVX600 phones is used for local call recording with
a USB thumb drive.
