Interface Cables

Most interface connectors are keyed for correct insertion. Keying ensures that the pin-1 wire in the cable connects to pin 1 in the connectors on both ends.

When you disconnect an interface cable, take care to grasp the cable connector, rather than the cable itself, to avoid stress on the cable.

Drive Cable Configurations

Your system can accommodate many different drive configurations, each with specific cable requirements. Table3-1 shows the cable requirements for common

drive configurations.

DC Power Cables

Each drive must connect to a DC power cable from the system power supply. These power cables are used for the 3.5-inch diskette drive, 5.25-inch devices,

and hard drives.

NOTICE: To avoid electrical damage to internal system components, install a cover connector on any unused connectors on hard-drive power cables.

CAUTION: Only trained service technicians are authorized to remove the system cover and access any of the components inside the system.

Before performing any procedure, see your Product Information Guide for complete information about safety precautions, working inside the

computer, and protecting against electrostatic discharge.
