Epica DGX 16 and Epica DGX 32 Instruction Manual
4. Blank board plate – Remove the screw that holds the board plate in place (for the Epica DGX 32,
see FIG. 69; for the Epica DGX 16, see FIG. 70). Pull the plate out of the board slot opening (the tab
on the end of the board plate fits in a slot near where the ejector handle would otherwise go). The
plate consists of an aluminum sleeve with a black metal piece, which slides in and out of the sleeve.
Or
Current board – Remove the pan head screw that holds the board in place (for the Epica DGX 32,
see FIG. 69; for the Epica DGX 16, see FIG. 70). Push on the board’s extractor handle as far as it
will go (about a 45° angle). With the handle extended, carefully pull the board straight out of the
board slot. Place the board in an ESD approved static shield bag and set aside.
Caution: Each Epica DGX 16 and 32 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: For SC Optical boards, do not remove dust plugs from SC fiber connectors until Step 11.
5. New board for an Epica 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
board slot (FIG. 69).
New board for an Epica DGX 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 board
slot (FIG. 70). Note that Input boards have board guides at the top of the slot and board guides for
the Output boards are at the bottom of the slot due to their reversed orientation in the enclosure.
