Before installing the board, be sure to turn off the power to the DSP1D and disconnect the power cord.
You need to remove the front cover of the DSP1D to install any board. To install the PDB1D board, you also need to remove the
left side cover.

shown in the picture. Do
not remove any other
screws. Keep the re-
moved screws in a safe
place since you will need
them to re-attach the
cover.
2. As shown in the picture,
remove the cover by
opening from the right
side to avoid damage to
the hardware on the left
side of the rack.
