4.
If applicable – Label and disconnect all cables on the board being replaced. If cables from adjoining boards obstruct
access, label and disconnect them as necessary.
If the enclosure is not powered down:
For disconnecting an SC Optical Input Board
– Before disconnecting the fiber cables, disconnect the
power on the DGX TX Modules that are connected to the inputs.
For disconnecting an SC Optical Output Board
– Before disconnecting the fiber cables, disconnect the
switches for those output connectors.
5.
Remove blank board plate
– Remove the screw that holds the board plate in place (for Enova DGX 32, see
FIG. 125; for Enova DGX 8/16/64, see FIG. 126). 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, and an EMI (Electromagnetic Interference)
gasket.
Or
Remove current board
–
Remove the pan head screw that holds the board in place (for the Enova DGX 32, see
FIG. 125; for the Enova DGX 8/16/64, see FIG. 126). 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.

Each Enova DGX board has an EMI gasket along one edge of the faceplate. 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 and DXLink Fiber Boards, do not remove dust plugs from their fiber connectors
until Step 12.
