Disk drive diagrams
Introduction
Disk drives are mounted on a steel disk drive carrier, which also
holds the backplane connector and, for drive assemblies with
power packs, the power pack. The following diagrams of the
disk drives show the view from the disk drive carrier-side, and
show the drives as if the carrier were transparent.
You can identify a drive as Seagate, Maxtor, or DEC by
comparing the positions of the jumpers on the drive with the
diagrams. When you look at the jumper diagrams for Seagate
drives, imagine that you are looking at the side or end view of
the drive, with the disk drive carrier at the top.
A cutout on the disk drive carrier may allow you to see and
change jumper settings for the SCSI ID of a Maxtor drive.
Note 1: Cutouts are not present on the disk drive plate to
accommodate Seagate and DEC disk drives.
Note 2: The following disk drive diagrams show settings for the
primary and secondary disks. You should use the primary disk
settings for any disk drive in an unshadowed multi-node system.
You should only use the secondary disk setting for the
shadowing disk.
