External Expansion Modules

These modules can be used to add additional ports to an IP Office systems. The number of external expansion modules supported depends on the control unit type. Each module uses an external power supply unit  supplied with the module. A locale specific power cord for the PSU must be ordered separately.

IP500 System with External Expansion Module

•Systems running in IP Office Basic Edition mode support up to 8 external expansion modules so long as the system extensions limit is not exceeded.

•Each external expansion module is supplied with a blue 1 meter (3'3'') expansion interconnect cable. This cable must be used when connecting to expansion ports on the rear of a control unit.

•! Important: External Expansion Module Power
In order to be detected and operated correctly, external expansion modules must start before the IP Office control unit. Normally this achieved by connected all expansion modules to the same power strip as the control unit. The control unit applies a short delay to its own start-up process to ensure that expansion modules powered on at the same time as it are detected.
