to take advantage of the speed this new technology offers. The blue connector
connects to the onboard IDE connector interface and the other connector(s) to
your hard drive(s). Consult the documentation that came with your disk drive for

IDE Connectors
There are two IDE connectors (one blue
and one white) on the serverboard. IDE#1
(blue) is designated as the Primary IDE
drive. The white connector is designated as
the Secondary IDE drive and is reserved
for Compact Flash Card use only. (See the
note below.) See the table on the right for
pin defi nitions.
Note: The white slot is reserved for Compact
Flash Cards only. Do not use it for other
devices. If populated with a Compact Flash
Card, IDE#1 (the blue slot) will be available
for one device only. For the Compact Flash
Card to work properly, you will fi rst need to
enable with JCF1 and connect a power cable
to JWF1.
