IBM 2193, 6345, 2194 manual Removing and adding drives, Identifying signal cable connectors

Removing and adding drives

Your computer has four drive bays to accommodate various types of drives.

See the section “Looking inside the system unit” on page 7-7 for the location and description of the drive bays.

Identifying signal cable connectors

When you install a drive of any type, you must attach the signal cable (also called the data cable) from the drive to a connector on the system board. The following table identifies each connector on the system and the type of drive that uses the connection. Note that the first two connectors are for IDE/ATA ATAPI drives (such as hard disk drives and CD-ROM drives), while the third connector is for diskette interface drives (such as diskette drives or tape drives).

If the machine type of your system is 2193, use the following illustration to identify the signal cable connectors on your system board:

System board connector	Interface type	Type of drive using the connector
Primary IDE – J4	IDE/ATA ATAPI	Preferred location for the hard disk drives.
Secondary IDE – J5	IDE/ATA ATAPI	Preferred location for a CD-ROM drive.
Diskette – J14	Standard diskette	Diskette and tape drives

If the machine type of your system is 2194 or 6345, use the following illustration to identify the signal cable connectors on your system board:

System board connector	Interface type	Type of drive using the connector
Primary IDE – J11	IDE/ATA ATAPI	Preferred location for the hard disk drives.
Secondary IDE – J12	IDE/ATA ATAPI	Preferred location for a CD-ROM drive.
Diskette – Floppy 1	Standard diskette	Diskette and tape drives

When attaching a drive signal cable to any of these connectors, take note of the pin 1 indicator (usually marked by colored stripes or dots) on the edge of the cable to ensure it aligns with pin 1 on the connector.
