Seagate 1200 SSD 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.

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 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. Reformatting the drive is only required if 
the application requires a different logical block size. 

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.

Cabinet cooling must be designed by the customer so that the temperature of the drive will not exceed temperature 
conditions specified in Section 6.5.1, "Temperature."

The rack, cabinet, or drawer environment for the drive must provide heat removal from the assembly. The system designer 
should confirm that adequate heat removal is provided using the temperature measurement guidelines described in Section 
6.5.1.

Forced air flow may be required to keep temperatures at or below the temperatures specified in Section 6.5.1 in which case 
the drive should be oriented, or air flow directed, so that the least amount of air flow resistance is created while providing air 
flow. Also, the shortest possible path between the air inlet and exit should be chosen to minimize the travel length of air 
heated by the drive and other heat sources within the rack, cabinet, or drawer environment.

If forced air is determined to be necessary, possible air-flow patterns are shown in Figure 21. The air-flow patterns are 
created by one or more fans, either forcing or drawing air as shown in the illustrations. Conduction, convection, or other 
forced air-flow patterns are acceptable as long as the temperature measurement guidelines of Section 6.5.1 are met.
