Drive cabling information

Your system includes three different types of drive cables. Each drive cable is clearly labeled, indicating cable-type and showing which end is connected to the appropriate connector on the system board and which end is connected to the drive.

Use the diskette drive connector cable to connect the diskette drive. Use the standard IDE connector cable to connect IDE devices such as CD drives and standard IDE hard drives. Use the SCSI LVD cable to connect LVD-compatible SCSI devices. A terminator comes installed on this cable.

You can also obtain two optional cables for your system. The IDE DMA-66 cable is used to connect DMA-66-compatible hard drives, and the SCSI SE cable is used to connect single-ended SCSI devices and requires termination, either on the device or as a plug-in terminator on the cable.

3.5-inch diskette or CD drives

Both the 3.5-inch diskette drive and 5.25-inch CD drives are secured in the chassis by removable rails. The rails let the drives slide into and out of the guides in the front bays. Extra rails are included with your system and are clipped to the outsides of the drive cages, inside the case.

Replacing the 3.5-inch diskette or CD drive

To replace the drives:

1Turn off the system and disconnect the power cord, modem cord (if installed), and all external peripheral devices.

2Remove the left side cover panel. (See “Removing the side cover” on page 18 and “Preventing static electricity discharge” on page 15.)

3Remove the bezel. (See “To remove the bezel:” on page 19.)

4Locate the 3.5-inch diskette or 5.25-inch CD drive you want to replace.

5Remove the power and data cables from the back of the drive, noting their locations and orientations. (You will reconnect these cables after you install the new drive.)
