9.6.4.1 Mating connectors for ST446452W models
Use a non-shielded 68-conductor cable connector consisting of two rows of 34 male contacts with adjacent
contacts 0.050 inch (1.27 mm) apart.
Recommended mating wide connector part numbers are:
[1] See Figure 11.
The drive device connector is a non-shielded 68-conductor connector consisting of two rows of 34 female pins
with adjacent pins .050 inch apart. The connector is keyed by means of its shape (see Figure 12).
[1] Open-end type (in-line application) connector used. Terminators disabled.
[2] Host need not be on the end of the daisy chain. Another device can be on the end with the terminator, the
host having no terminator.
[3] Total interface cable length must not exceed that specified in Section 9.6.3.1 (including host adapter/initia-
tor). The number of devices allowed depends on data transfer rate. See Table 10.
[4] SCSI ID7 has highest arbitration priority. Priority is ID 7 to ID 0, then ID 15 to ID 8. (ID 8 has the lowest pri-
ority).
[5] Last drive on daisy chain.
[6] If end device, external terminator and closed-end type 68-pin connector used. Install terminator enable
(TE) jumper plug.
