Figure 4-2: Example of a primary switch unit and 3 groups of secondary devices in a LAN setup
1 = Frame F01 = Primary switch unit
2 = Frame F02 = Secondary device 1
3 = Frame F03 = Secondary device 2
4 = Frame F04 = Secondary device 3
5 = Frame F05 = Secondary device 4
6 = Frame F06 = Secondary device 5
7 = Frame F07 = Secondary device 6
8 = Frame F08 = Secondary device 7
9 = Test control system (PC and software)
Connect all switch units to the LAN. In your primary switch unit, configure the other
switch units as secondary devices, using the host name (or IP address) of each device.
Using IP addresses instead of host names can lead to address conflicts in the LAN,
depending on procedures in your DHCP server. See
Once you have set up your switch units as primary and secondary devices, you can
work with the primary device's interface alone. The primary device then controls the
behavior of all secondary devices.
The user interface of secondary devices is limited to displaying status and module
information. You cannot switch any relays or output channels. The
dialogs are absent.
dialog of each secondary device shows not only its hostname, but also the
"Primary Hostname". This information tells you, which R&S
OSP is the primary device
that controls the secondary device.
The R&S
OSP firmware does not permit cascaded secondary devices, hence, no "terti-
dialog of a secondary switch unit has
no "Secondary Devices" section (as in a primary switch unit).
How to exit from interconnection mode
●
The standard method for releasing a secondary switch unit is by removing its entry
in the primary switch unit's settings at
