Installing a Hard Drive into a Drive Carrier
1. After removing a drive carrier, remove the six screws securing the dummy drive tray to
the drive carrier. Lift the tray out.
2. Install the new hard drive into the carrier with the printed circuit board side facing down
and with the mounting holes in the drive aligned with those in the carrier.
3. Secure the drive to the carrier by tightening all six screws. The logic and power
connections to the drive will be supplied through the backplane.
