As many as eight SCSI devices can share a SCSI bus. All data is sent between the system and the devices on the cable. Each of the eight SCSI devices is identified by a number from 0 to 7, called a SCSI ID. Each device looks at all the data on the bus, but takes only the data that has the correct SCSI identification. SCSI ID 6 is reserved for the host controller, leaving seven SCSI ID numbers available to identify SCSI devices. SCSI default settings for each expansion box are listed in Table 1-5. The settings listed give optimal performance on most systems. However, for most applications, SCSI IDs can be set arbitrarily as long as no two devices have the same ID. 1-6 BA46 Storage Expansion Box Each device has either a set of switches or a set of jumpers (removable electrical connectors) that can be set for a specific ID. The RZ5x disk drives use external switches on the back of the expansion box (see Figure 1-2 ). Use the following rules when setting SCSI IDs: · As many as seven devices can be connected on one bus. · As many as three expansion boxes can be connected on one bus. · Each device must have a unique SCSI ID. · The length of the SCSI bus cannot be more than 4 meters (13 ft). Table 1-5 lists the recommended SCSI ID numbers for the drives. Table 1-5 Device IDs for SCSI Devices ------------------------------------------------------------ ID Number Type of SCSI Device ------------------------------------------------------------ 7 Open number, may be used for any drive 6 Reserved as the system controller ID 5 Tape/Floppy drives, factory configured 4 CDROM drive, factory configured 3 Hard disk drive, factory configured first disk 2 Hard disk drive, factory configured second disk 1 Hard disk drive, factory configured third disk 0 Hard disk drive, factory configured fourth disk ------------------------------------------------------------ Each expansion box with an RZ56/RZ57 disk drive ships from the factory with the SCSI switches (Figure 1-2) set for one or two of these devices. Verify the switch settings when you install the expansion box. BA46 Storage Expansion Box 1-7 Figure 1-2 SCSI Switch Location for RZ5x Disk Drives Chapter 2 describes each of the mass storage devices in further detail and lists the SCSI ID settings for each one. 2 Mass Storage Devices ------------------------------------------------------------ This chapter describes the optional mass storage devices that can be installed in the BA46 expansion box, and provides the SCSI ID settings that should be used for each device. The chapter is organized into the following sections: Section 2.1 RZ5x Hard Disk Drives Section 2.2 TLZ04 Cassette Tape Drive Section 2.3 TZ30 Cartridge Tape Drive Section 2.4 TZK10 (QIC) Cartridge Tape Drive Section 2.5 RRD42 CDROM Compact Disc Drive Refer to Chapter 3 for removal and replacement procedures for the devices. 2-1 2-2 Mass Storage Devices 2.1 RZ5x Hard Disk Drives The RZ55 whole disk drive is a full-height drive with a storage capacity of 332 Mbytes. The RZ56/RZ57 hard disk drives are full-height drives with a storage capacity of 600 Mbytes. These drives store information on a non- removable disk. 2.1.1 SCSI ID Settings for RZ5x Hard Disk Drives To verify the SCSI ID switch setting for the RZ5x drives, turn the expansion box with the back of the unit facing you. The switches (Figure 1-2) are red and white, and surrounded by a label (do not remove the label). If there is one RZ5x installed in the expansion box, the right three SCSI ID switches on the back of the box determine the SCSI ID switch setting for that drive. If there are two RZ5x disk drives installed in the expansion box, the left three SCSI ID switches on the back of the box determine the SCSI ID switch setting for the second RZ5x disk drive. Verify the SCSI switch settings for the RZ5x drives before you install the drive. 1. Verify that the switches are in the following positions (left to right): DOWN, UP, UP 1 . The RZ5x disk drive ships from the factory with a default SCSI ID of 3. 2. Check the SCSI ID settings of all devices connected to the system and choose an unused ID for the new drive. If a drive is being replaced, the SCSI ID from the drive it is replacing should be used. Table 2-1 lists the SCSI ID switch settings for the RZ5x disk drives. ------------------------------------------------------------ 1 UP = on, DOWN = off Mass Storage Devices 2-3 Table 2-1 RZ5x Hard Disk Drive SCSI ID Switch Settings ------------------------------------------------------------ SCSI ID on SCSI-B Bus 1 2 3 ------------------------------------------------------------ 0 DOWN DOWN DOWN 1 DOWN DOWN UP 2 DOWN UP DOWN 3 DOWN UP UP 4 UP DOWN DOWN 5 UP DOWN UP 6 UP UP DOWN 7 UP UP UP ------------------------------------------------------------ 2-4 Mass Storage Devices 2.2 TLZ04 Cassette Tape Drive The TLZ04 cassette tape drive can be used for software backup.

The heads physically read data from and write data to the cassette tape. Digital strongly recommends that you handle cassette tapes as described in the BA46 Storage Expansion Box Owner 's Guide (PN EK-STEXP-IG-001) and clean the heads as described in this section. CAUTION Using any other procedure to clean the drive heads will void the product warranty. Digital recommends that you perform the head-cleaning procedure about every two weeks, or after every 25 hours of drive usage. Clean the drive heads as follows: 1. Turn the on/off switch to the on position. 2. Ensure that the busy indicator LED is on. 3. Insert the head-cleaning cassette that came with your tape drive (PN TLZ04-HA) into the drive. The head-cleaning cassette automatically starts the head cleaning process. The drive ejects the head-cleaning cassette after approximately 30 seconds. 4. Place a check mark on the head cleaning cassette in the space provided, every time you clean the drives. Under normal conditions, the head-cleaning cassette is good for 25 cleanings. Additional cassettes are available from your Digital sales representative or through DECdirect (Telephone: 1-800-DIGITAL).
