System Power Cables

Power cables come from the power supply and are attached to the standard storage devices.
System power cables vary in length and provide connector sizes to accommodate a variety
of supported storage configurations.
Power cable connectors are keyed to fit only in the correct position. The following figure
shows the power cable connectors.

Cabling an IDE or SCSI Device

All storage devices require a power and signal cable connection. Devices shipped with the
system are already connected. To connect an optional IDE or SCSI device, proceed as
follows. If you are installing a second diskette drive, see "Cabling a Diskette Drive."
Connect the appropriate connector on the IDE signal cable to the IDE connector
1.
on the IDE device. Align the colored edge of the cable with the pin 1 side of the
device connector.
Take care to prevent bending drive connector pins. Be sure to align the IDE cable
connector as shown in the figure.
Locate an available power connector coming from the power supply (see "System
2.
Power Cables").

connector on the system board).
