13. Execute a test switch using a connection on the new board (see page 40).
If the test switch does not work, see “Board Troubleshooting” below.
14. Epica DGX 32 only – Replace the connector numbering plate that was removed in Step 2.
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. 72). This
command retrieves information on the crosspoint size of the virtual matrices (VMs).
The default configuration that ships with almost all systems includes two VMs (VM 0 and VM 1) with
the crosspoint size for each set at a full 32x32 for an Epica DGX 32 (eight input and eight output boards)
and at 16x16 for an Epica DGX 16 (four input and four output boards).
If the crosspoint size is less than full (e.g., 24x24 in an Epica DGX 32) 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 the crosspoint size is large enough to accommodate the new board and you still cannot execute
switches, contact technical support (see page 42).
Updating the Configuration File
If the configuration file requires updating (as explained in the previous section), 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 the default configuration of 16x16 or 32x32
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 42),
so they can add support for the board change to the modified file before you download the file
to the CPU (requires XNConnect).
