6. Press the drive cage release lever down and then rotate the cage out of the
server until the drive-cage retention tab locks into place and the open ends of
the drive slots and installed drives are facing you. Ensure that the drive cage
locks into place over the drive-cage retention tab by rotating the drive cage all
the way out of the server.
7. Attach the blue guide rails to the side of the drive using the screws that are
provided.
8. Slide the drive into the drive cage until the plastic tabs on the drive guide rails
lock into place in the drive cage. Clear any cables that might impede the
replacement of the drive cage.
9. Connect one end of the SCSI signal cable into the back of the drive and make
sure that the other end of this cable is connected into the SCSI connector on
the system board. See "Power and signal cables for internal drives" on page
54 for additional information about cabling drives and "System-board internal
connectors" on page 91 for the location of SCSI connectors on the system
board. If there are open connectors on the cables connecting existing SCSI
drives, these cables can be used to connect the new drive.
10. Route the signal cable so that it does not block the air flow to the rear of the
drives or over the microprocessor and memory.
11. Connect the power cable to the back of the drive. The connectors are keyed
and can be inserted only one way.
12. Push the drive cage outward, and press in on the drive-cage release tab; then,
rotate the cage back into the server.
