Identifying Guide Screws
When installing drives, you must install guide screws to ensure the drives
correctly align in the drive cage. Compaq has provided extra guide screws.
They are located behind the side panel of the server. Some options use
5.25 M3 metric screws and some use HD 6-32 screws. The metric screws
supplied by Compaq are black.
