Replacing a Hard-Drive Carrier
Two versions of hard-drive carriers are used with your system. The version for
SATA hard drives has a single set of (four) mounting holes on the side rails.
The second version, called a SAS/SATAu hard-drive carrier, has an extra four
mounting holes to enable either a "SAS" and "SATAu" mounting position.
When using the SAS/SATAu hard-drive carrier, observe these rules with
regard to your system:
• Use only SAS hard drives with SAS/SATAu drive carriers.
• Use only the "SAS" mounting position on the carrier. (The SATAu position
is reserved.)
Figure3-6 illustrates a SAS hard drive being installed in a SAS/SATAu hard-
drive carrier.

Removing a Hard Drive From a Hard-Drive Carrier

Remove the four screws from the slide rails on the hard-drive carrier and
separate the hard drive from the carrier.

Installing a Hard Drive Into a Drive Carrier

1Insert the hard drive into the hard-drive carrier with the connector end
of the drive at the rear. See
Figure 3- 6
.
2Viewing the assembly as shown in
Figure3-6, a
lign the screw holes on
the hard drive with the rear set of holes on the hard drive carrier.
When aligned correctly, the rear of the hard drive will be flush with the
rear of the hard-drive carrier.
3Attach the four screws to secure the hard drive to the hard-drive carrier.
