Locating extra guide screws
Each drive requires four guide screws to ensure the drive lines up correctly in the drive cage and locks
in place. HP provides extra guide screws for installing new drives.
●
The extra screws are mounted in the front of the chassis, under the front bezel (see
Removing the
front bezel on page 65).
●
Four black M3 metric screws are used to install most drives.
●
Four silver 6-32 standard screws are used to mount 3.5–inch hard disk drives. The fifth is used for
bezel security (see
Front bezel security on page 65).
●
If you are replacing the primary hard drive, you must remove the four silver and blue 6-32
isolation mounting guide screws from the old hard drive and install them in the new hard drive.
