® 4.3 Internal connectors 1. Floppy disk drive connector (34-1 pin FLOPPY1) This connector is for the provided floppy disk drive (FDD) signal cable. Insert one end of the cable to this connector, then connect the other end to the signal connector at the back of the floppy disk drive. Pin 5 on the connector is removed to prevent incorrect cable connection when using a FDD cable with a covered Pin 5. LAN2 FLOPPY1 PIN 1 NOTE: Orient the red markings on the floppy ribbon cable to PIN 1. P5MT Series Floppy disk drive connector 2. Primary IDE connector (40-1 pin PRI_IDE1) This connector is for an Ultra ATA100/66/33 signal cable. The Ultra ATA 100/66/33 signal cable has three connectors: a blue connector for the primary IDE connector on the motherboard, a black connector for an Ultra ATA 100/66/33 IDE slave device (optical drive/hard disk drive), and a gray connector for an Ultra ATA 100/66/33 IDE master device (hard disk drive). If you install two hard disk drives, you must configure the second drive as a slave device by setting its jumper accordingly. Refer to the hard disk documentation for the jumper settings. • Pin 20 on the IDE connector is removed to match the covered hole on the Ultra ATA cable connector. This prevents incorrect insertion when you connect the IDE cable. • Use the 80-conductor IDE cable for Ultra ATA 100/66/33 IDE devices. ® 4-10 LAN2 PRI_IDE1 PIN 1 NOTE: Orient the red markings (usually zigzag) on the IDE ribbon cable to PIN 1.
