CAUTION:
When the computer is plugged into an AC power source, there is always voltage
applied to the system board. You must disconnect the power cord from the power source before
opening the computer to prevent system board or component damage.
When installing additional drives, follow these guidelines:
!
Use the green pull tabs to disconnect the diskette and hard drive cables from the
drives.
!
For optimal performance, connect hard drives to the primary IDE controller.
Connect expansion devices, such as IDE CD-ROM, tape, and diskette drives to the
secondary controller.
!
You must install guide screws to ensure the drive will line up correctly in the drive
cage. Compaq has provided extra guide screws, installed in the base of the
computer chassis, next to the power supply. Some options use M3 metric thread
hardware, such as CD-ROM drives. The Compaq-supplied metric screws are
black.
