8.0 Installation
Cheetah disc drive installation is a plug-and-play process. There are no jumpers, switches, or terminators on
the drive.
SAS drives are designed to be used in a host system that provides a SAS-compatible backplane with bays
designed to accomodate the drive. In such systems, the host system typically provides a carrier or tray into
which you need to mount the drive. Mount the drive to the carrier or tray provided by the host system using four
6-32 UNC screws. Do not over-tighten or force the screws. You can mount the drive in any orientation.
Note. SAS drives are designed to be attached to the host system without I/O or power cables. If you
intend the use the drive in a non-backplane host system, connecting the drive using high-quality
cables is acceptable as long as the I/O cable length does not exceed 4 meters (13.1 feet).
Slide the carrier or tray into the appropriate bay in your host system using the instructions provided by the host
system. This connects the drive directly to your system’s SAS connector. The SAS connector is normally
located on a SAS backpanel. See Section 9.4.1 for additional information about these connectors.
Power is supplied through the SAS connector.
The drive is shipped from the factory low-level formatted in 512-byte logical blocks. You need to reformat the
drive only if you want to select a different logical block size.

8.1 Drive orientation
The drive may be mounted in any orientation. All drive performance characterizations, however, have been
done with the drive in horizontal (discs level) and vertical (drive on its side) orientations, which are the two pre-
ferred mounting orientations.
