get it started. If you are replacing Drive #1, also remove Drive #2 and label it as
the “good” drive.

holes on the drive with the holes on the chassis. Screw in the 4 screws for the
drive. If you removed the “good” drive as well, slide it into the Drive #1 slot and
secure it with the 4 screws.

3Reconnect the SATA cable(s). If you removed both SATA cables because you are
replacing Drive #1, be sure that the cables are connected to the correct drives (see
the illustration on page 4 for connections).

server (see the illustration on page 2).
