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.
2.1 Enhanced IDE Connector (CN1)
You can attach two IDE (Integrated Device Electronics) drives to the
PCA-6154/6154L’s internal controller. The PCA-6154/6154L CPU
card has an EIDE connector, CN1.
Wire number 1 on the cable is red or blue, 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 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.
Note: We don't recommend connecting to a Seagate
