Appendix E – Board Replacement
Replacing or Adding a Board
Important: 1) When replacing a board, be sure to install the new board in the same slot that held the
original board to ensure the switching commands are correct. 2) When adding a board, if switching
commands don't work after the new board is installed, the configuration file may need to be updated
(see "Board Troubleshooting" on page 140).
In almost all cases, Epica DGX 32 systems are configured to accommodate a full enclosure's worth of
boards and do not require modification to the configuration file when a board is added. If you cannot
execute switches with the new board after it has been installed, see "Board Troubleshooting" on page 140.
Important: Cable management bars are not to be used as handles to remove or install boards.
Note: Read each step entirely; many have tips to avoid damage to internal cables and connectors.
To remove and replace an Epica DGX 32 Board:
1.
Loosen the two captive screws (one on each end) that hold the connector numbering plate at the top
of the boards and set the plate aside.

2.
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.
3.
If applicable – Remove the cable management bar (two screws at the top and one screw at the bottom
of the bar).
4.
Blank board plate – Remove the screw at the top of the board plate.
Pull the plate up and out of the board slot opening (the tab on the lower edge of the board plate fits
in a slot at the bottom of the opening). 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 large screw at the top of the board.
Push down 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 (FIG. 7).
Place the board in an ESD approved static shield bag.
Remove screw, push board extractor handle down, and then pull board straight out
