Adding or Replacing a Board
When replacing a board, be sure to install the new board in the same slot that held the original board to make sure the
switching commands are correct.
Enova DGX 100 Series Switchers are configured to accommodate a full enclosure’s worth of boards and do not require
modification to the configuration file when a board is added. In the following procedure, read each step entirely.
IMPORTANT:
The Audio Insert/Extract board is not hot-swappable; when installing an AIE Board, be sure to power down
the system.
To remove and replace an Enova DGX board:

If applicable - Label and disconnect all cables on the board being replaced. If cables from adjoining boards
obstruct access, label and disconnect them as necessary.
