Compaq Professional Workstation AP550 Maintenance and Service Guide
IMPORTANT:
You must install guide screws to ensure that the drives line up correctly in the drive cage.
Compaq has provided extra guide screws, installed in the front of the workstation chassis behind the
front bezel. Some options use 5.25 M3 metric screws, and some use HD 6-32. The Compaq-supplied
metric screws are black.
NOTE:
For optimal performance, connect hard drives to the primary controller. Connect expansion
devices, such as IDE CD-ROM, tape, and diskette drives, to the secondary controller.
