Black Box SCSI-2 LVD instruction

CHAPTER 4: Installation and Configuration

Take these steps to connect internal SCSI devices to the Adapter:

1.If you haven’t already done so, turn OFF and unplug the PC, disconnect all other devices from it, and remove its cover.

2.If you haven’t already done so, prepare each internal SCSI peripheral for installation: configure the device’s SCSI ID and termination. (If you’ll be using the included cable, or some other preterminated cable, all of the devices should have termination turned OFF. If you’ll be using a non-terminated cable, turn the last device’s termination ON and leave the others OFF.) For instructions, see the device’s documentation as well as Sections 3.2 and 3.3.

3.Install each internal SCSI peripheral in your computer. Refer to your computer’s and peripherals’ documentation for instructions.

4.Plug one end of your internal SCSI cable into the Adapter’s appropriate internal SCSI connector. (If you’re using the cable included with the Adapter, plug in the unterminated end.) Make sure the colored stripe that runs the length of one edge of the cable is aligned with Pin 1 of the Adapter’s connector. The cable should be keyed for proper insertion. Figure 4-4 below shows how to plug in this cable.

5.Plug the internal cable’s other connectors into the internal SCSI peripherals that you installed in step 3. (If you are using the cable included with the adapter, or some other cable with 68-pin connectors, and any of the peripherals are Narrow [50-pin] devices, you will need to attach 50-pin- female-to-68-pin-female adapters, such as our product code EVNSCT38, between the cable and the device.) Also attach internal power cables to any of these devices that get their power from the PC. Refer to the instructions for doing these things in the peripherals’ documentation. Remember to terminate the last internal device.

SCSI-2 LVD specifications

The Black Box SCSI-2 LVD (Low Voltage Differential) represents a significant advancement in data storage and connectivity technology, particularly in environments requiring high performance and reliability. As a variant of the SCSI (Small Computer System Interface) standard, it is optimized for faster data communication, essential for modern computing needs.

One of the main features of SCSI-2 LVD is its capability to handle increased data transfer speeds compared to its predecessors. It supports a maximum data transfer rate of up to 80 MB/s, which is double that of the original SCSI-2 single-ended signaling. This increase in speed is largely due to the differential signaling that LVD employs, allowing for reduced electromagnetic interference and extended cable lengths while maintaining signal integrity. The technology effectively converts the SCSI bus into a more robust system that can accommodate various devices without compromising performance.

The SCSI-2 LVD standard is backward compatible, meaning that it can interface with older SCSI devices, albeit at reduced speeds. This compatibility is significant for users looking to upgrade their systems without discarding existing hardware. This makes SCSI-2 LVD an attractive choice for enterprise environments where legacy systems are common.

Another key characteristic is the flexible cabling options provided by SCSI-2 LVD. It can support cable lengths of up to 12 meters, which is beneficial for large data center configurations where space between devices can be substantial. This extended range does not typically come at the expense of performance, ensuring that data integrity remains high, even over longer distances.

In terms of technology, LVD employs lower voltage levels, which not only contributes to greater power efficiency but also minimizes heat generation in devices. This is particularly crucial in data centers where temperature management can impact hardware longevity and reliability. The combination of lower voltage use and differential signaling makes SCSI-2 LVD well-suited for high-density environments.

Error correction and handshaking features are also integral to SCSI-2 LVD, enhancing its robustness against data loss during transmission. These characteristics make it a reliable choice for applications requiring consistent and high-speed data access, such as server arrays and high-performance computing tasks.

Overall, Black Box SCSI-2 LVD stands out due to its impressive speed, compatibility, and extensive cabling options, positioning it as a reliable solution for demanding data environments. It effectively bridges the gap between legacy systems and modern technology, ensuring that users can optimize their data handling capabilities without significant disruption.
