2.2 Installation in the Densité frame
The
DDA-1133
and its associated connector rear panel must be mounted in a DENSITÉ-2 or DENSITÉ-3-series
frame. It is not necessary to switch off the frame’s power when installing or removing the card. See the appropriate
DENSITÉ Frame manual for detailed instructions for installing cards and their associated rear panels.
•
The rear panel must be installed first, before the card is inserted into the frame.
•
When used with a dual-slot rear panel, the DDA-1133
must be installed in the right-most of the two slots
covered by the panel in order to mate with the panel’s connectors. If it is placed in the wrong slot, the front
panel LED will flash red. Move the card to other slot for correct operation. No damage will result to the card if
this occurs.
