In general, switch boards in the panel lid can be replaced as follows:

2. Label any sockets and cables before you unplug them to ensure the
cables are replaced in the correct sockets. This is especially important if
you will be removing more than one board.
3.
Disconnect the data and power cables from the board.
4. Remove the screws (from four to seven depending on board type).
5.
Carefully remove the board from the lid.

adjacent board, remove the remaining 4 screws of that left board, then
remove the 6 screws of the right adjacent switch board and carefully tilt the
board out.
