Enclosure Features Connectors
Not every pin in the connector block for
system case features is used. Which
features are used depends on the spe-
cific case design. If your case does not
have a Keyboard Lock, you can still con-
nect a Power LED lead to Pin 20 and
either Pin 16 or 18. Refer to the chart
at right for the pin assignments.
