Savvio 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 Ib 0 45 in Ib 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 10 m 32 8 ft 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 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 You need to reformat the drive only if you want to select a different logical block size Figure 11 Ph
