[. . . ] Quantum User Reference Guide SDLT 220 & SDLT 320 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. [. . . ] To avoid losing data or damaging the tape drive, inspect cartridges: Before loading a new cartridge After dropping a cartridge or subjecting it to physical shock When the tape drive becomes inoperable after loading a cartridge When you receive a shipment of data cartridges that shows any sign of shipping damage. These cards can provide one of three possible SCSI interface types. The multimode single-ended (MSE) card provides either a low-voltage differential (LVD) mode running at 80 MB/second or singleended (SE) mode running at 40 MB/second. The high-voltage differential (HVD) mode runs at 40 MB/ second. A single-ended drive only works with a single-ended SCSI controller card. A differential drive only works with a differential SCSI controller card. Single-ended SCSI interfaces support up to 7 devices on the SCSI chain using cable lengths up to 3 meters. Differential SCSI interfaces support up to 15 devices on the SCSI chain using cable lengths up to 25 meters. A low-voltage differential SCSI interface only works with a single-ended device if the controller is switched to singleended mode. !For more information about SCSI interfaces and SCSI bus settings, visit www. dlttape. com. 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 220 and SDLT 320 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. If the drive is the only SCSI device, leave the SCSI ID set to the default setting. !This setting is typically reserved for the SCSI controller. You can change the SCSI ID using the push-button switch on the back of the drive. Press the switch buttons above or below the number display with the point of a pencil to increase or decrease the ID number. Connections: Single Drive | C4 C4 Terminate upper SCSI port. Connections: Single Drive The Super DLTtape drive performs best when it is the only device connected to the SCSI bus. If the 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. [. . . ] If the tape drive is not defined within the system, the SCSI adapter does not interact well with the tape drive. Make sure your controller card and the SCSI bus are operating in the same mode, preferably LVD. If the controller card or the SCSI bus are operating in SE, the tape drive switches to SE.
