3. If you are installing a drive in a bay covered by a bezel blank, remove the front bezel then remove
the bezel blank. See
Bezel Blanks on page 115 for more information.
4. Install two M3 metric guide screws in the lower holes on each side of the drive. HP has provided
four extra M3 metric guide screws on the front of the chassis, under the front bezel. The M3 metric
guide screws are black. Refer to
Installing and Removing Drives on page 127 for an illustration of
the extra M3 metric guide screws location.
CAUTION: Use only 5-mm long screws as guide screws. Longer screws can damage the internal
components of the drive.
NOTE: When replacing the drive, transfer the four M3 metric guide screws from the old drive to
the new one.
5. Position the guide screws on the drive into the J-slots in the drive bay. Then slide the drive toward
the front of the computer until it locks into place.
