8.0Installation

Note. These drives are designed to be used only on single-ended (SE) or low voltage differential (LVD) busses. 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 J5- Auxiliary on the LW model), or via the drive to host I/O signals on the LC model. Some users connect cables to J6 or J5-Auxiliary and perform the set-up using remote switches.

Configure drive options

For option jumper locations and definitions refer to Figures 18, 19, and 20. 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

Drives are shipped from the factory low level formatted with 512 byte sectors.

8.1Drive ID/option select header

Figures 18 and 19 show views of the drive ID select jumper connectors. Figure 20 shows the option select jumper connector for all models. Figure 18 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.

ST3300007LW/LC, ST373207LW/LC, ST3146707LW/LC specifications

Seagate's ST3146707LW/LC, ST373207LW/LC, and ST3300007LW/LC are part of the company's renowned line of hard disk drives (HDDs), specifically designed for enterprise and high-performance computing environments. With their reliability and performance, these drives have become popular choices for data centers and critical applications requiring extensive storage capabilities.

One of the standout features of these models is their capacity to handle large volumes of data. The ST3146707LW/LC has a capacity of 146GB, while the ST373207LW/LC offers 73GB, and the ST3300007LW/LC comes with a substantial 300GB. These capacities make them well-suited for applications that require not only high storage space but also rapid access to data.

In terms of performance, these drives utilize a 10,000 RPM spindle speed, which significantly enhances data access times and overall performance. The combination of fast rotational speeds with Seagate's advanced caching algorithms allows for swift data retrieval, making these drives ideal for environments where speed is crucial.

These HDDs also employ the SCSI (Small Computer System Interface) interface, which promises high data transfer rates and reliability in enterprise-level applications. The Ultra320 SCSI interface can support transfer rates up to 320 MB/s, ensuring that the drives can efficiently communicate with other system components.

Another key technology featured in these models is Seagate's Adaptive Error Correction technology, which enhances data integrity and reliability. This feature helps in the detection and correction of errors that can occur during data transfer, reducing the risk of data loss.

Performance consistency is critical in enterprise environments, and these drives are built to endure the demands of 24/7 operation. They are designed with robust mechanisms to withstand temperature fluctuations, shock, and vibrations commonly found in data center settings.

In summary, the Seagate ST3146707LW/LC, ST373207LW/LC, and ST3300007LW/LC hard drives exemplify advanced features and technologies tailored for enterprise storage solutions. With significant capacities, impressive spindle speeds, SCSI connectivity, and reliability-focused technologies, these drives remain a valuable asset for businesses relying on stable and high-performance data storage.
