18 Hawk 2 (Wide bus) Family Install Guide, Rev. C Initial setup information For the initial setup connect the cables, set the SCSI bus address and enable or disable (as required by system configuration), the SCSI I/O line terminator resistors (model "W" drives only). Note whether the drive model number ends in W, WC or WD. These procedures are described in paragraphs following. SCSI interface cable connection The drives covered by this manual are SCSI interface drives.

DC power connection, 68 pin SCSI I/O connector Model ST12400WC model drives receive power from the host computer through the 80 pin combined SCSI I/O and power connector (not shown, since a separate DC power cable not required). No separate DC power connector is provided on the drive.
20 Hawk 2 (Wide bus) Family Install Guide, Rev. C 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 (or remote ID select location) should be suspected. On "WC" model drives the SCSI ID can be and presumably will be, set over the 80 pin interface by the host computer. Unless directed to do so by the system documentation, no jumpers should be installed for address selection.
Hawk 2 (Wide bus) Family Install Guide, Rev. C 21 Model numbers that end in "WD" have differential I/O circuits and these drives and "WC" mode drives have no provisions for terminators on the drive PCB. The system manufacturer must provide some external means of I/O line termination. The ST12400W/WD drives can provide power for external terminators if the TP jumper is installed on the last position on the right end of J2. See Figure 3a.

Hawk 2 (Wide bus) Family Install Guide, Rev. C 23 Drive configuration Each disc drive has option select header connectors on the back, side and front where jumper plugs are installed to select the way that the drive is to be configured and to select its ID (0 - 15) on the I/O bus. See notes following Figure 3b.
24 Hawk 2 (Wide bus) Family Install Guide, Rev. C ST12400WC family 80 pin SCSI I/O drives On Hawk 2 family, ST12400WC model drives there is no J1-auxiliary. J6 can be used to set drive ID, but the host probably does it over the 80 pin interface. J6 may be used to drive external LED's and connect the synchronized spindle signal to other drives and the host. This is described in the notes following Figure 3b.

28 Hawk 2 (Wide bus) Family Install Guide, Rev. C Notes for Figure 3a, 3b and 3c: [1] Notes explaining the functions of the various jumpers on jumper header connectors J2, J1-auxiliary and J6 are given below in left to right order of jumper position. The term "default" means as standard OEM units are configured when shipped from factory. "Off" means no jumper is installed; "On" means a jumper is installed. Off or On underlined is factory default condition.
Hawk 2 (Wide bus) Family Install Guide, Rev. C 29 [4] The drive time-shares the ID and LED/SSP functions of J6 and J1-auxiliary. That is, a cable may be attached to one of these headers to pick up the synchronized spindle reference signal (SSP) and three signals that light external LED indicators. If lines for external ID selection are not also included in the cable, jumper plugs must be used on the header not having a cable connected in order to establish drive ID.
30 Hawk 2 (Wide bus) Family Install Guide, Rev. C continued from previous page Off On On Off On On WP On Off PE On Off TE On Off Drive spindle does not start until Start Unit command received from host. Spindle Startup is delayed by SCSI ID times 12 seconds after power is applied, i.e., drive 0 spindle starts immediately when DC power connected, drive 1 starts after 12 second delay, drive 2 starts after 24 second delay, etc. Drive spindle starts when Start Unit command received from host.
Hawk 2 (Wide bus) Family Install Guide, Rev. C 31 continued from previous page TP TP Off Off On Off Off On On On (Not applicable to "WC" model drives) No terminator power is connected to drive terminators or SCSI bus I/O pin 26. Drive supplies its own terminator power only. Jumper on this position is factory default. Drive supplies power to I/O pin 26 of SCSI bus; none to internal terminators.
32 Hawk 2 (Wide bus) Family Install Guide, Rev. C J6 and J1-Auxiliary Jumper Installation Jumper Function Description A3,A2,A1,A0* Drive ID on SCSI Bus. The drive ID is binary coded positionwise i.e., jumper in position A3 is drive ID 8, in position A2 is drive ID 4, in position A1 is ID 2, position A0 is ID 1 and no jumpers is ID 0. Default is ID = 0. Either J1-auxiliary or J6 may be used to select drive ID.
Hawk 2 (Wide bus) Family Install Guide, Rev. C 33 Drive installation This section describes the physical mounting of the drive in the host cabinet and the logical installation as a system member, which is called drive setup. Disc drive mounting Do not touch the connector pins or any PCB components without observing static-discharge precautions. Always handle the drive by the frame only. The drive may be mounted in any orientation. • See notes on Figures 4 and 5 pertaining to proper drive installation.
