User manual QUANTUM 818122001

[. . . ] Quantum User Reference Guide SDLT 600 User Manual Statements for Class A Equipment (Internal Tape System) This is a Class A product. This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. [. . . ] The tape drive operates best when the host computer and host end of the cable have one of the following types of connector. SCSI Connectors High-density 68-pin Micro DB68 or Mini DB68 SCA 80-pin Hot Swap Connector Very High-density Interconnect Connector The tape drive will, however, operate with other host-end connectors. Fibre Channel Cables and Connectors Fiber Optic Cable Fibre Channel versions of the SDLT 600 tape drive (internal model only) have one Fibre Channel port. The Fibre Channel port is equipped with a Small Form-factor, Pluggable (SFP) converter for connecting the fiber optic cable. You may have to supply the SFP for the other end of the cable; some host bus adapters have the transceiver already built in to the adapter, in which case, you do not have to supply the SFP for the other end of the cable. Note: Both ends of the cable require a transceiver. C3 | Setting the SCSI ID C3 3 3 Setting the SCSI ID This section describes how to set the SCSI ID on the tabletop tape drive. For information about setting the SCSI ID on an internal tape drive, refer to the SDLT 600 Product Manual. Each device connected to a SCSI bus must have a unique SCSI ID number. The factory preset SCSI ID is 3 for the tabletop tape drive and 5 for the internal tape drive. Ensure that your tape drive's SCSI ID is unique on your SCSI bus. You can change the SCSI ID using the push-button switch on the back of the tape drive. Use the point of a pencil to press the buttons above or below the number display to increase or decrease the ID number. If the tape drive is the only SCSI device, leave the SCSI ID set to 3, the default setting. !This setting is typically reserved for the SCSI controller. Connecting the SCSI Model as a Single Device | C4 C4 Terminate upper SCSI port. Connecting the SCSI Model as a Single Device The SDLT 600 tape drive performs best when it is the only device connected to the SCSI bus. If the SDLT 600 tape drive is the only SCSI device you intend to connect to the SCSI bus, follow these steps: 1. Make sure the host computer and all peripheral devices are powered off. Never connect the tape drive while the host system or peripheral devices are powered on. 2. Connect a terminator to the upper SCSI connector on the back of the tape drive. 3 !The SCSI controller terminates one end, while a terminator on the tape drive terminates the other end. 3. Connect one end of the SCSI cable to the lower connector on the back of the tape drive. Connect the other end of the SCSI cable to the SCSI connector on the host computer. For more information about connecting the SDLT 600 tape drive, refer to the SDLT 600 Product Manual. C5 | Connecting the SCSI Model in a Daisy Chain C5 Terminate upper SCSI port. 3 Connecting the SCSI Model in a Daisy Chain If you are adding your SDLT 600 tape drive to a SCSI daisy chain, follow these steps: 1. Ensure that all devices have unique SCSI IDs. C3 2. Make sure the host computer and all peripheral devices are powered off. Never connect the tape drive while the host system or peripheral devices are powered on. 3. [. . . ] Fragmented disks and files take much longer to back up. The SDLT 600 tape drive supports block sizes up to 16 MB. In general, the larger the block size, the better the throughput. Many older software applications default to a 512-byte block size, which results in poor performance. [. . . ]
