8.0Installation

Note. These drives are designed to be used only on single-ended (SE) or low voltage differential (LVD) bus- ses. Do not install these drives on a high voltage differential (HVD) bus.

The first thing to do when installing a drive is to set the drive SCSI ID and set up certain operating options. This is usually done by installing small shorting jumpers on the pins of connectors J2 and J6 on the PCBA (or J1- Auxiliary on the LW/LWV model), or via the drive to host I/O signals on the LC/LCV model. Some users connect cables to J6 or J5-Auxiliary and perform the set-up using remote switches.

If your system is “SCAM” (SCSI Configured Automatically) compliant, the system assigns the drive SCSI ID over the interface, so there is no need to be concerned about drive SCSI ID. Setting the drive SCSI ID jumpers doesn’t hurt anything, but is not necessary.

If your system is not “SCAM” compliant you do need to set the drive SCSI ID using the ID jumpers.

Configure drive options

For option jumper locations and definitions refer to Figures 15, 16, and 17. Drive default mode parameters are not normally needed for installation. Refer to Section 9.3.2 for default mode parameters if they are needed.

Ensure that the SCSI ID of the drive is not the same as the host adapter. Most host adapters use SCSI ID 7 because ID 7 is the highest priority on both 8 and 16 bit data buses.

If multiple devices are on the bus set the drive SCSI ID to one that is not presently used by other devices on the bus.

If the drive is the only device on the bus, attach it to the end of the SCSI bus cable. The user, system integra- tor, or host equipment manufacturer must provide external terminators.

Note. For additional information about terminator requirements, refer to Sections 9.8 and 9.9.

Set all appropriate option jumpers for desired operation prior to power on. If jumpers are changed after power has been applied, recycle the drive power to make the new settings effective.

Installation instructions are provided by host system documentation or with any additionally purchased drive installation software. If necessary see Section 10 for Seagate support services telephone numbers.

Do not remove the manufacturer’s installed labels from the drive and do not cover with additional labels, as the manufacturer labels contain information required when servicing the product.

Formatting

It is not necessary to low level format this drive. The drive is shipped from the factory low level formatted in 512 byte sectors.

Reformat the drive if a different spare sector allocation scheme is selected.

High level formatting the drive involves assigning one or more partitions or logical drives to the drive volume. Follow the instructions in the system manuals for the system into which the drive is to be installed.

8.1Drive ID/option select header

Figures 15 and 16 show views of the drive ID select jumper connectors. Figure 17 shows the option select jumper connector for all models. Figure 15 shows the drive’s J5-auxiliary jumper connector. Both J5-auxiliary and J6 have pins for selecting drive ID and for connecting the remote LED cable. Only one or the other should be used, although using both at the same time would not damage the drive. The notes following the figures describe the functions of the various jumper positions on the connectors J2, J5-Auxiliary and J6. Suggested part number for the jumpers used on J2 is Molex 52747-0211 (Seagate part number 77679052). A bag with the two jumper plug types is shipped with the standard OEM drives.
