| The drive uses the standard 80 pin SCA-2 connector which conforms to
the mechanical requirements of SFF 8451. The connector is expected to be
used in an environment which uses a common connector structure for racking
disk drives in a
cabinet. The connector allows for plugging a drive directly into a backplane
by providing the necessary electrical connection.
Mechanical stability and device retention must be provided by a mechanism
outside the drive. The drive also conforms to the
electrical specification of SPI-4 document, Annex C “Single Attachment for
Small SCSI Disk Drives.”
As shown in the figure below, the 80 pin SCA-2 card has a single jumper
block ( J6).
As described in Section 7.2.2, “SCSI signal connector (80-pin SCA-2
model)” on page 31, some of the jumper pins on J6 of
the 80-pin models can also be controlled through the 80-pin SCA-2 connector.
These controls work as a logical OR between
the Option Jumper Block and the SCA-2 connector. |
