Board Troubleshooting
If you cannot execute switches with the new board after it has been installed, the first thing to do is
verify the configuration of the system by entering ~scri5v3! in the splash screen (FIG. 49). This
command retrieves information on the size of the virtual matrices (VMs).
The standard configuration that ships with almost all systems includes two VMs with the crosspoint size
for each set at a full 32x32, i.e., eight input and eight output boards with four connectors each (FIG. 49).
If the crosspoint size is less than 32x32 (e.g., 24x24) and the new board increases the size past the size
indicated on the splash screen, then the system was customized for a non-standard crosspoint size that is
not large enough to accommodate the new board. The configuration file must be updated before the new
board will work (see “Updating the Configuration File” below).
If you cannot execute switches and the crosspoint size is large enough to accommodate the new board,
contact technical support (see page 40).
Updating the Configuration File
If the configuration file requires updating (as explained above), read both choices listed to determine
how to proceed.
 If the system’s configuration file has not been modified since it was shipped from the factory,
enter ~def! in the splash screen to establish a standard 32x32 configuration with two VMs.
 If the original configuration has been modified in any way (e.g., local presets were added),
we recommend sending a copy of the modified file to technical support (see page 40),
so they can add board support to the modified file before you download the file to the CPU
(requires XNConnect).
