J2 is a four-pin connector that attaches to a cable that connects to the
hard disk LED mounted on the computer enclosure. The LED indicates
data transfers (SCSI bus activity.)
J3 is a two-pin header for the dirty cache LED. This can be connected
to an LED on the computer enclosure. The LED will be lit when data in
the cache has not yet been written to the storage device.
J4 and J5 are three-pin headers that specify the type of SCSI termination
for channel 0 and channel 1, respectively.
