PBX Cascading Putting a Cascaded PBX into Operation 11.3 Putting a Cascaded PBX into Operation Proceed as follows to put a cascaded PBX system into operation: 1. Take the additional slave system out of its packaging and place it in immediate proximity to the master system. Connect a system telephone to the slave system for a later performance check. Use the Upn1 press-fit terminal of the basic module (only OpenCom 130) or one of the Upn ports of an interface card. 2. Back up the master system data. For further information, refer to the online help topic System: Data Backup. 3. Switch off the master system if it is operating. Disconnect the module from the power supply by pulling out the mains plug. 4. If necessary, install the add-on module for the master system. If you use an OpenCom 130 as the slave system, you also have to install an add-on module. 5. Connect the two modules by means of two suitable cables as described above. 6. Power on the two PBXs. The order in which you do this does not matter. 7. In the Telephony: Ports: Slots dialogue of the master system's Configurator, click on Slave. Select the slave Type in the Slave: Change dialogue. If a possible slave system was detected when the system was started, there is an additional entry in the Type field ("Online: PBX type"). If you select this entry, the settings for Type and MAC address are applied automatically. Please note: If you change the type of slave system later on, the port settings that have been made will be deleted. The master system then initialises the slave system. This may involve transfer of firmware (operating software) from the master system to the slave system. The transfer process is only executed for two OpenCom 130 / 150 PBXs. This can take a few minutes. 8. Configure the system telephone connected to the slave system for testing purposes in the Configurator. In the Telephony: Ports: Upn dialogue, click on one of the additionally displayed entries of the type Upn 1/0/n (1: slave system, n: Upn port number). 150
