18 PCA-6753F User's Manual
The following sections tell how to make each connection. In most
cases, you will simply need to connect a standard cable. All of the
connector pin assignments are shown in Appendix A .
Warning! Always completely disconnect the power cord from
your chassis whenever you are working on it. Do not
make connections while the power is on. Sensitive
electronic components can be damaged by a
sudden rush of power. Only experienced electronics
personnel should open the PC chassis.
Caution! Always ground yourself to remove any static charge
before touching the CPU card. Modern electronic
devices are very sensitive to static electric charges.
Use a grounding wrist strap at all times. Place all
electronic components on a static-dissipative
surface or in a static-shielded bag when they are not
in the chassis.
2.6 Enhanced IDE connector (CN1)
You can attach two IDE (Integrated Device Electronics) drives to the
PCA-6753F internal controller. The PCA-6753F CPU card has an
EIDE connector, CN1.
Wire number 1 on the cable is red or blue, and the other wires are
gray. Connect one end to connector CN1 on the CPU card. Make sure
that the red (or blue) wire corresponds to pin 1 on the connector (on
the right side). See Chapter 1 for help in finding the connector.
Unlike floppy drives, IDE hard drives can connect in either position
on the cable. If you install two drives, you will need to set one as the
master and one as the slave. You do this by setting the jumpers on the
drives. If you use just one drive, you should set it as the master. See
the documentation that came with your drive for more information.
Connect the first hard drive to the other end of the cable. Wire 1 on
the cable should also connect to pin 1 on the hard drive connector,
which is labeled on the drive circuit board. Check the documentation
that came with the drive for more information.
Connect the second drive, as described above, on CN1.
