NSTALLATION
Constellation ES.3 disk 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 accommodate 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 M3 x 0.5 metric screws. When tightening the screws, use a maximum torque of 4.5
in-lb +/- 0.45 in-lb. Do not over-tighten or force the screws. You can mount the drive in any orientation.
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
N
OTE
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 11.4.1 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.
