8 Hawk 2LP (Wide) Installation Guide, Rev. A 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.
Hawk 2LP (Wide) Installation Guide, Rev. A 9 • Low-Level formatting: All Hawk 2LP wide 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 subdivided into "partitions" which behave as individual drives within the system.
10 Hawk 2LP (Wide) Installation Guide, Rev. A 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. Drives should be sent to the repair depot through the purchase source, if possible. Please observe the following cautions. Caution. • Handle drive with care.
Hawk 2LP (Wide) Installation Guide, Rev. A 11 • Place drive on a flat, static dissipative surface and handle with extreme care. Always follow all EOS/ ESD precautions to avoid damage to the electrical assemblies. Shipping: When transporting or shipping a drive, a Seagate approved container must be used. Keep your original box. They are easily identified by the Seagate Approved Package label. Shipping a drive in a nonapproved container voids the drive warranty.

16 Hawk 2LP (Wide) Installation Guide, Rev. A Initial setup 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 (Hawk 2LP family "W" models only). These procedures are described in paragraphs following. Note whether drive model number ends in W, WD, WC or DC. SCSI interface cable connection The Hawk 2LP family wide drives are SCSI interface drives.
Hawk 2LP (Wide) Installation Guide, Rev. A 17 DC Power connection Hawk 2LP family "W/WD" model drives receive DC power through a 4 pin connector mounted on the PCB in line with the SCSI I/O connector. See figure below.

18 Hawk 2LP (Wide) Installation Guide, Rev. A SCSI address selection On "W" and "WD" model drives, make sure that the SCSI bus address jumper(s) are properly set for the bus address assigned to the drive. See Figures 3a and 3b showing the bus address select header and the jumper configurations that select addresses 0 through 15. ID7 has the highest priority during bus arbitration (on both 8 and 16 device systems). Bus arbitration priority decreases to ID0, then ID15 down to ID8.
Hawk 2LP (Wide) Installation Guide, Rev. A 19 Terminator resistor packs As a factory installed option, Hawk 2LP family model "W" drives can have terminator resistor packs that are permanently installed, but can be enabled or disabled by jumper plug. See jumper in Figure 3a. If you are installing a single drive, the terminator resistor packs must remain enabled.
20 Hawk 2LP (Wide) Installation Guide, Rev. A Read/Write head auto-park Seagate disc drives described herein park the heads automatically at power off. This feature requires no operator intervention. Optional parity bit enable Some systems require parity bit checking. Consult the system documentation for the specific requirements. See Figure 3a for location of Parity Bit enable jumper. Jumper-installed enables parity reporting by the SCSI bus.

22 Hawk 2LP (Wide) Installation Guide, Rev. A 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 or to select its ID on the I/O bus. See "Initial setup information" and see notes following Figure 3c. Some host systems have a remote drive ID selection capability.
Hawk 2LP (Wide) Installation Guide, Rev. A 23 Hawk 2LP family "WC" and "DC" model 80 pin SCSI I/O drives On Hawk 2LP family "WC" and "DC" model drives there is no J1-auxiliary connector. J6 can be used to set drive ID, but the host probably does it over the 80 pin interface. J6 can also be used to drive the external drive activity LED indicator signal. The alternate use of J6 is described in the notes following Figure 3c.

A 27 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.
28 Hawk 2LP (Wide) Installation Guide, Rev. A [4] The drive time-shares the ID and BUSY LED functions of J6 and J1-auxiliary. That is, a cable may be attached to one of these headers to pick up the signal that lights the external BUSY LED indicator. 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.
