Reinstalling the AIE Board
Caution: The AIE Board has an EMI (Electromagnetic Interference) gasket along one edge of the
face plate. Handle the boards carefully to avoid dislodging or damaging the gasket on the board
being installed and
the gasket on the adjacent board or blank plate.
Caution: Do not try to install an AIE Board in any of the standard input or output board slots.
(Standard board slots are indicated by the numbers on the numbering plate that is above the slots on
an Enova DGX 32 and between the input and output slots on an Enova DGX 8/16.) An AIE Board
can only be installed in an I/O expansion board slot
.
To reinstall the AIE Board:
1.
Enova DGX 32 – With the board’s extractor handle in the extended (unlocked) position, line up the
board’s edges on the board guides that are along the top and bottom of the AIE slot.
Or
Enova DGX 8/16 – With the board’s extractor handle in the extended (unlocked) position, line up
the board’s edges on the board guides that are along the left and right of the AIE slot. Note that
boards on the input side have guides at the top of the slot and that guides for boards on the output
side are at the bottom of the slot due to their reversed orientation in the enclosure.
2. Begin pushing the AIE Board into the AIE slot until the extractor handle starts to engage the metal
extractor plate (the extractor handle moves into its folded position).
When the extractor handle starts to lift, flip the handle toward the center of the board until it snaps
into its folded (locked) position, which firmly seats the board.
3. Insert and tighten the screw (removed previously) that holds the board in place.
4. Enova DGX 32 only – When wiring is complete (see below) and functionality is checked, replace
the connector numbering plate that was removed previously.
Important: If for any reason an I/O expansion board slot is left empty, be sure to attach a blank plate
to cover the empty slot.
Attaching Wires
When attaching audio wires, you may find it easier to unplug the audio connectors before you start.
For connector details, see Audio Specifications on page 102.
Important to Know When Wiring AIE Boards
Audio boards and connectors are positioned vertically on the Enova DGX 32 and horizontally
on the Enova DGX 16. Be sure to note the labeling for the wiring on the “R” (right channel)
and the “L” (left channel) wires in FIG. 62.
Enova DGX 8/16 only – the orientation of audio Insert/Extract Board in the right AIE slot
places the number 1 audio connector on the far right of the board.
Note: If wiring the audio connectors to balanced audio input devices, see page 109 for options.
To wire audio connectors:
1.
Press a very small tip screwdriver (or a T-pin) into the square hole to release the tension clamp
(if the clamp does not release fully, you may need to use the screwdriver as a lever to release it).
2. Insert the wire into the round hole.
