Section 1. General description

The Seagate ST43400N/ND Elite 3 disc drives are high speed, random access digital data storage devices. They communicate with an initiator using the Small Computer System Interface (SCSI). The drive is shown in Figure 1, and its specifications are listed in Table 1 on the following page.

The drive is a component for installation in an enclosure designed for the drive. The enclosure design must ensure adequate cooling for the drive, and it must address the requirements for grounding and for shielding of emissions. The reference manual (publication 83327640) presents guidelines for designing the enclosure, but the design is your responsibility.
