Pulsar.2 SAS Product Manual, Rev. B
11.0
Installation
Pulsar.2 drive installation is a plug-and-play process. There are no jumpers 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 the drive must be mounted. 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. The drive can be mounted in any orientation.
Note.
SAS drives are designed to be attached to the host system without I/O or power cables. If the intent
is to 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 10 meters (32.8 feet).
Slide the carrier or tray into the appropriate bay in the host system using the instructions provided by the host
system. This connects the drive directly to the system’s SAS connector. The SAS connector is normally located
on a SAS backpanel. See Section 12.4.1 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. Reformatting the drive is
only required if the application requires a different logical block size.

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