32 SBC-556/L User ManualIDE hard drive connector (CN5)You can attach one or two Enhanced Integrated Device Electron-icshard disk drives to the SBC-556’s internal controller. The SBC-556’sIDE controller uses a PCI local-bus interface and supports fasterdata transfer.Connecting the hard driveConnecting drives is done in a daisy-chain fashion and requiresone of two cables, depending on the drive size. 1.8" and 2.5" drivesneed a 1 x 44-pin to 2 x 44-pin flat-cable connector. 3.5" drives use a1 x 44-pin to 2 x 40-pin connector.Wire number 1 on the cable is red or blue, and the other wires aregray.1. Connect one end of the cable to CN5. Make sure that the red (orblue) wire corresponds to pin 1 on the connector, which islabeled on the board (on the right side).2. Plug the other end of the cable to the Enhanced IDE hard drive,with pin 1 on the cable corresponding to pin 1 on the hard drive.(See your hard drive’s documentation for the location of theconnector.)Connect a second drive as described above.Unlike floppy drives, IDE hard drives can connect to either end ofthe cable. If you install two drives, you will need to set one as themaster and one as the slave by using jumpers on the drives. If youinstall just one drive, set it as the master.
