Avaya IP Office 400 External Expansion Modules can be used to add additional ports to an IP400 system. The number of expansion modules supported depends on the control unit type. Expansion modules, except the WAN3 10/100 module, connect to expansion ports on the rear of the control unit, using a 1 meter (3'3") cable supplied with the expansion module. Each module uses an external power supply unit supplied with the module.
