Power the VVX Expansion Module
The Polycom VVX Expansion Modules are powered and signaled by VVX business media phones and
require minimal setup. The expansion modules are powered by VVX phones using an auxiliary cable that
connects the modules and phone. After you connect the module to a phone, the module is automatically
configured to work with the phone. Note that you cannot connect paper display and color display
expansion modules together on the same phone.
Note: Sufficient Power for VVX Expansion Module
Powering the VVX expansion modules depends on the VVX phone’s power management
system. If the phone does not have the power capabilities to support an expansion module, a
message displays on the phone after the module is connected. See the section Power Values for
more information.
To connect the VVX expansion module to your VVX phone:
» Connect an auxiliary cable from the AUX port on the phone to the AUX IN port on the expansion
module.
The LED lights on the module’s line keys flash red and green as the module starts up. After the first
module is on, you can connect up to two additional modules to your VVX phone.
To connect multiple VVX expansion modules:
1 Connect an auxiliary cable from the AUX Out port on the first module connected to the phone to the
AUX In port on the second module.
2 Connect an auxiliary cable from the AUX Out port on the second module to the AUX In port on the
third module.
The LED lights on the line keys light up for each connected module as the expansion modules start
up.
After you connect the expansion modules to a VVX phone, you can view information about and check the
status of the connected expansion modules on your VVX phone. Expansion modules are listed in the
Status menu in the order each module is connected to the phone. For example, EM1 is the first
expansion module connected to the VVX phone.
To view the status of an expansion module on the phone:
1 Select Settings > Status.
2 In the Status menu, select the module you want to view.
Information for the expansion module—the type of module, software version, assembly revision,
and serial number—displays.
