Troubleshooting
If the performance of your switch units does not meet your expectations, try the follow-
ing approaches for optimization:
Firmware version
Make sure that all your switch units in an
configuration use the same
firmware version. Otherwise, flawless communication between the switch unit is not
ensured. See
Chapter 12.3, "Firmware Update"
Device messages (user interface)
If your switch unit shows error messages, temporary warnings or other messages in
the graphical user interface (GUI), as described in
follow the instructions or hints provided.
Examples:
●
A bad connection after mounting a module results in an error message. For exam-
ple, to find out if the module bus connectors of a twin-bus module are crossed-over
(erroneously swapped), see
solve the problem, you can try to repeat the
●
If the firmware does not detect any module, check your hardware configuration.
This event can be relevant especially, if you start a switch unit that holds a remote
control module R&S
OSP-B200R: As long as the corresponding satellite unit
R&S
OSP-B200S2 is not connected or not powered up, the firmware cannot detect
modules in the satellite. In this case, if the base switch unit holds only that remote
control module, the firmware cannot find any switch module.
●
There are many possible reasons for a path not being switchable. Refer to the
description of "Path C" in
in the section on
.
●
If there is a device or mainboard EEPROM error (data missing or corrupted), you
can try a restart of the switch unit.
●
If the scanning of SPI addresses on module bus M20 failed, you can try a restart.
If you cannot solve an operating problem, collect all
and contact
the Rohde
&
Schwarz customer support.
Touchscreen display
If the RGB-LED touchscreen display does not function properly, for example after start-
ing up the switch unit, restart it by pressing the [Pwr] button on the front panel.
Network connection issues
If you cannot connect to your R&S
OSP via the LAN to use the graphic user interface
") or RC commands, try the following:
●
Enter the primary switch unit's hostname rather than its IP address into your
browser or scripting program
