Connecting Diskette and IDE Devices

NOTE If only one IDE device is installed, make sure to use the ribbon cable connector
furthest from the main logic board connector.
Also, when IDE devices have been installed in both internal drive bays, make sure that
the ribbon cable has no twists between the two IDE drives.
To connect diskette and IDE devices, perform the following:
1) Unlatch device bay and power supply subassembly.
2) Lift up on subassembly and lock in place.
3) Connect supplied ribbon cable to appropriate device. If necessary, refer to the illustration in the
appropriate data cable connection topic listed below.
4) Connect appropriate power cable to device.
5) Release device bay and power supply subassembly rear latch.
6) Close subassembly and then secure to chassis using front locking mechanism.
7) Replace and lock cover.
8) Connect external devices and restore power.
9) Run BIOS Setup utility to configure computer.
NOTE Make sure the cable is connected with correct orientation. Most cables and sockets
are keyed so you cannot connect them backwards. If the cable or device is not keyed,
connect pin 1 of cable to pin 1 of device's socket.
Pin 1 of the cable is on the edge with colored stripe. Pin 1 of the device's socket
should be marked with a number or symbol at one end of socket or with a number or
symbol printed on circuit board near one end of socket. If necessary, refer to the
device's documentation for pin 1 orientation.
