8 Hawk 1LP Family Installation Guide, Rev. D Installation Overview Installation of the drive can be divided into distinct phases. Some of these may not be applicable to all system installation requirements. Refer to the individual drive installation sections for specific information on your drive model. • Drive configuration: Select those drive features that are appropriate to install the drive in the system. This is done by installing or removing user configuration jumpers found on the drive PCB.
Hawk 1LP Family Installation Guide, Rev. D 9 • Low-Level formatting: All Hawk 1LP family drive models are low-level formatted at the factory and do not require this step during installation. If an installed drive is low-level formatted, all user data will be lost. Note: Seagate Technology assumes no liability for lost user data. • Partitioning and high level formatting: A drive can be sub-divided into "partitions" which behave as individual drives within the system.
10 Hawk 1LP Family Installation Guide, Rev. D Product repair information Service requirements The special facilities required for the manufacture of these drives generally prohibit repair in the field. If problems occur during installation, please contact your supplier for assistance. Do not attempt to disassemble or repair.

Hawk 1LP Family Installation Guide, Rev. D 17 Initial set-up information For the initial setup connect the cables or plug into a mounted connector (if applicable), set the drive ID on the bus and enable or disable the I/O line terminator resistor packs ("N" and some "NC" models). These procedures are described in paragraphs following. Note whether drive model number ends in N, ND or NC. SCSI interface cable connection Models Hawk 1LP family are SCSI interface drives.
18 Hawk 1LP Family Installation Guide, Rev. D DC Power connection "N" and "ND" model family drives receive DC power through a 4 pin connector mounted on the PCB next to the SCSI I/O connector. See figure below. 50 Pin SCSI I/O Connector DC Power Connector 4 3 2 1 Pin 1 2 3 4 Power +12V +12V RET + 5V RET + 5V Figure 1. DC power connection, 50 pin SCSI I/O connector "NC" model drives receive power from the host computer through the 80 pin combined SCSI I/O and power connector.
Hawk 1LP Family Installation Guide, Rev. D 19 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. On "NC" model drives the SCSI ID can be and presumably will be, set over the 80 pin interface by the host computer.
20 Hawk 1LP Family Installation Guide, Rev. D Model numbers that end in "ND" have differential I/O circuits and these drives and some "NC" model drives have no provisions for terminators on the drive PCB. The system manufacturer must provide some external means of I/O line termination. The "ND" model 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.

22 Hawk 1LP Family Installation Guide, Rev. D Drive configuration Each disc drive has one or more option select header connectors on the back, side or front where jumper plugs are installed to select the way that the drive is to be configured or to select its ID on the I/O bus. See notes following Figure 3b. Hawk 1LP family N/ND models (50 pin SCSI I/O) On Model N/ND drives either J6 (on the front of the drive) or J5 (on the side behind the DC Power connector) may be used to set the drive ID.
Hawk 1LP Family Installation Guide, Rev. D 23 Hawk 1LP family NC models (80 pin SCSI I/O) On Model NC drives there is no J5. J6 can be used to set drive ID, but the host probably does it over the 80 pin interface. J6 is used to select other configuration options as has previously been described, or is described in the notes following Figure 3b.
