DC Power connection

The drives receive DC power through a 4 pin connector mounted on the PCB next to the SCSI I/O connector. See figure below.

SCSI address selection

Make sure that the SCSI bus address jumper(s) are properly set for the bus address assigned to the drive. See figures 3a and 3b showing the bus address select header and the jumper configurations that select addresses 0 through 7. Typically the primary boot device is set to ID 0, and the subsequent SCSI drives are jumpered in ascending order. Bus addresses 0 through 6 should be used (the host adapter usually uses address 7). If the drive LED shows no on/off activity when the host is trying to communicate with it, an incorrect bus address selection at the drive should be suspected.

ST31230N/ND, ST32430N/ND specifications

The Seagate ST31230N/ND and ST32430N/ND hard drives were integral components of the data storage landscape during their time, showcasing the innovation of Seagate in the field of magnetic storage technology. Both models offered capacities suitable for various applications, catering primarily to enterprise environments that required reliability and performance.
