22 PCA-6180 User's Manual
2.1 Introduction
You can access most of the connectors from the top of the board
while it is installed in the chassis. If you have a number of cards
installed or have a packed chasis, you may need to partially remove
the card to make all the connections.
Note: If your chassis has only one empty expansion slot
to accommodate the CPU card, you can replace the
standard dual-slot bracket with the single-slot
bracket included in your PCA-6180 package, in
which case you will have to access the connectors
(CN31~34) on the extension I/O board from inside
the chassis.
2.2 Primary (CN1) and Secondary (CN2) IDE
Connectors
You can attach up to four IDE (Integrated Drive Electronics) drives to
the PCA-6180’s built-in controller. The primary (CN1) and second-
ary (CN2) connectors can each accommodate two drives.
Wire number 1 on the cable is red or blue and the other wires are
gray. Connect one end to connector CN1 or CN2 on the CPU card.
Make sure that the red/blue wire corresponds to pin 1 on the connec-
tor (in the upper right hand corner). See Chapter 1 for help finding
the connector.
Unlike floppy drives, IDE hard drives can connect in either position
on the cable. If you install two drives to a single connector, you will
need to set one as the master and the other as the slave. You do this
by setting the jumpers on the drives. If you use just one drive per
connector, you should set each drive as the master. See the documen-
tation that came with your drive for more information.
