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 U
pn
1 press-fit terminal of the basic module
(only OpenCom 130) or one of the U
pn
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 pur-
poses 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: U
pn
port number).
