Installing the Optional XG Plug-in System
3 Remove the four (4), black, XG Plug-in Board installation screws
that are secured to the inside of the installation lid. Unlatch and
remove the holder that secures the connector. Extend the con-
nector.
Keep the holder for use when the XG Plug-in Board is removed.
4 Remove the XG Plug-in Board from the ant-static bag.
CAUTION!
Before handling the XG Plug-in Board, be sure to touch a grounded, metal surface
in order to remove any static electricity from your clothes or body. Do not touch
any of the patterned surfaces of the board or its connector.
5 Insert the expansion connector of the MU100 into the connec-
tor of the XG Plug-in Board.
Make sure to insert the connector so that it faces the proper di-
rection and the right and left tabs of the expansion connector
lock into place (as shown in the illustration).
