The DAT24 drive provides a typical capacity of 24 Gbytes, assuming 2:1 data compression (native capacity is 12 Gbytes). The DAT24 tape drive can connect to a standard, single-ended SCSI or SCSI-2 interface. You can use a 50-conductor flat cable or a 25-signal twisted-pair cable to connect the drive to a SCSI host adapter. The cable should not exceed 6 meters (19.5 feet). The DAT24 drive is offered as internal and desktop versions: · · The internal version is available as a 3.5-inch or 5.25-inch tape drive. It provides a 50-pin, dual-row single-ended SCSI connector at the back of the drive. The desktop version provides two 50-pin, shielded connectors (ANSI Alternative 2) on the back panel. These connectors consist of two rows of ribbon contacts spaced 2.16 mm (0.085 in) apart. Either connector can be used as a SCSI IN or SCSI OUT connection. Table 1 on page 9 identifies the Certance DAT24 drive models and model numbers covered by this User's Guide. Table 1.

Topics covered in this chapter are: · · · "Unpacking and Inspection" on page 10 "Installing an Internal DAT24 Drive" on page 10 "Installing the Desktop DAT24 Drive" on page 18 Unpacking and Inspection Although drives are inspected and carefully packaged at the factory, damage may occur during shipping. Follow these steps for unpacking the drive. 1. 2. 3. Visually inspect the shipping containers and notify your carrier immediately of any damage. Place shipping containers on a flat, clean, stable surface; then carefully remove the contents. If the equipment is damaged, notify your Certance representative. Always save the containers and packing materials for any future reshipment. Installing an Internal DAT24 Drive Installing the internal DAT24 drive involves the following steps: 1. 2. 3. 4. 5. Observe the guidelines and cautions for handling internal tape drives. See "Internal Tape Drive Guidelines and Cautions" on page 11. Configure the drive. See "Configuring the Internal DAT24 Drive" on page 11. Mount the drive. See "Mounting an Internal DAT24 Drive" on page 15. Connect the power and interface cables. See "Connecting Power and Interface Cables" on page 17. Registering the tape drive. After you install the DAT24, register it. Registering it ensures that you will receive the latest information about the drive, as well as other product, service, and support information. For your convenience, you can register the DAT24 through our Web site at http://register.certance.com. NOTE: Internal drives come in two mounting configurations. Drives configured for 5.25-inch bays are identical to those designed for 3.5-inch bays, except that drive-mounting brackets have been added on each side of the drive. Installation procedures are the same for both drive configurations. 10 Installation Installing an Internal DAT24 Drive Internal Tape Drive Guidelines and Cautions The following guidelines and cautions apply to handling and installing the internal DAT24 tape drive. Keep them in mind as you install the internal drive. · · Handle the drive by the sides rather than by the top cover to reduce the risk of dropping the drive or damaging it during installation. Internal drives contain some exposed components that are sensitive to static electricity. To reduce the possibility of damage from static discharge, the drives are shipped in a protective antistatic bag. Do not remove the drive from the antistatic bag until you are ready to install it. Before you remove the drive from the antistatic bag, touch a metal or grounded surface to discharge any static electricity buildup from your body. Always lay the drive either on top of the antistatic bag or place it inside of the bag to reduce the chance of damage from static discharge. · · Configuring the Internal DAT24 Drive Before you install the internal DAT24 tape drive in your computer, you may need to set the drive's SCSI ID or other drive features. Most features are set using a bank of dip-switches on the underside of the drive (see Figure 1 on page 11). To control SCSI termination and terminator power, or to configure the drive for remote SCSI address selection, use the jumpers on the back of the drive, above the interface and power connectors. Dip switches Note: Drive is shown upside down SCSI jumper block Figure 1. DIP Switches and Jumpers for Internal DAT24 Tape Drives The default settings for internal DAT24 tape drives are: · · · · · · SCSI ID is 0. Drive reads and writes both MRS and non-MRS 4-mm media. Parity checking is disabled. Data compression is enabled. Power-on self-test diagnostics are disabled. SCSI termination is disabled. If the default settings are appropriate for your computer system, skip ahead to "Mounting an Internal DAT24 Drive" on page 15. Otherwise, proceed to "Changing DIP Switch Settings" on page 12. 11 Installation Installing an Internal DAT24 Drive Changing DIP Switch Settings Figure 2 on page 12 shows the location of DIP switches on the underside of the internal DAT24 drive. Factory-default settings for each switch are also shown in Figure 2 on page 12. These settings are described in detail on the following pages. Block of 10 dip switches O F F 1 2 3 4 5 6 7 8 9 10 Note: Drive is shown upside down Default dip-switch settings: S1 S2 S3 S4 S5 S6 S7* S8 S9 S10 ON OFF Key to dip-switch settings: SCSI ID SCSI ID Selection OFF ON OFF ON OFF ON OFF ON OFF OFF ON ON OFF OFF ON ON OFF OFF OFF OFF ON ON ON ON MRS Mode Parity Inquiry Data compression String Self-test UNIX Configuration 0 1 2 3 4 5 6 7 All MRS only Enable Disable Disable Enable Seagate Enable Archive Disable see text ON OFF *Some drives may be factory-configured to use the Archive inquiry string. Figure 2. DIP Switch Settings for Internal DAT24 Drives NOTE: If you change a DIP switch setting, the new setting does not take effect until you restart the drive or send a SCSI Bus Reset to the drive. SCSI ID Switches (Switches 1 through 3) Switches 1, 2, and 3 correspond to the SCSI device address identification bits 0 (least-significant bit), 1, and 2 (most-significant bit), respectively. The default setting is SCSI ID 0 (all three switches OFF). NOTE: Each SCSI device on a bus must have a unique SCSI ID. The SCSI host controller generally uses ID 7. In some systems, the boot drive uses ID 0. 12 Installation Installing an Internal DAT24 Drive Media Recognition System (Switch 4) · · Switch 4 ON = Media Recognition System mode disabled (default) Switch 4 OFF = Media Recognition System mode enabled The media-recognition system allows the drive to determine whether a DAT tape supports the DDS standard. Using non-DDS media may appear to give satisfactory results, but the inferior specifications of such media can cause data-integrity problems. Switch 4 enables or disables Media Recognition System (MRS) mode. If switch 4 is ON (the default setting), the drive reads or writes both MRS and non-MRS 4-mm media. If switch 4 is OFF, the drive reads and writes to MRS media, and reads from but does not write to 4-mm media. Parity Check (Switch 5) · · Switch 5 ON = Parity checking enabled Switch 5 OFF = Parity checking disabled (default) Switch 5 enables or disables parity checking for the SCSI bus. If switch 5 is ON, parity checking is enabled. If switch 5 is OFF (the default setting) parity checking is disabled, but parity is still generated by the drive. DDS Pass-through Mode (Switch 6) · · Switch 6 ON = DDS pass-through data compression disabled Switch 6 OFF = DDS pass-through data compression enabled (default) If switch 6 is OFF (the default setting), DDS pass-through data compression is enabled. If switch 6 is ON, data compression is disabled. NOTE: The setting of switch 6 can be overridden if the host computer issues the appropriate SCSI Mode Select command. Inquiry String (Switch 7) · · Switch 7 ON = Drive identifies itself as a Seagate DAT drive (default) Switch 7 OFF = Drive identifies itself as an Archive Python drive If switch 7 is ON, the drive generates a SCSI inquiry string that identifies it as a Seagate DAT drive. For compatibility with older software and operating systems, the drive can be configured as an Archive Python drive by setting switch 7 to OFF. 13 Installation Installing an Internal DAT24 Drive Power On Self Test (Switch 8) · · Switch 8 ON = Drive performs Power On Self Test Switch 8 OFF = Drive does not perform Power On Self Test (default) Switch 8 enables or disables execution of Power On Self Test (POST) diagnostics when powered on. If switch 8 is OFF (the default setting), the drive does not perform a POST. If switch 8 is ON, the drive responds to SCSI commands only after successful completion of the POST (about 5 seconds). UNIX Operating Systems (Switches 9 and 10) Switches 9 and 10 configure the DAT24 tape drive for use with UNIX operating systems. For more information, see Chapter 4, "UNIX Settings" on page 26. Jumper Settings Configuration jumpers on the back of the drive control SCSI bus termination and terminator power. The jumpers can also be used for remote SCSI address selection. Figure 3 on page 14 shows the locations of the jumper block and jumper settings for the internal DAT drive. Jumper Block 15 16 13 14 11 12 9 10 7 8 5 6 3 4 1 2 Jumper ON Remote SCSI ID Pins 5-6 OFF OFF OFF OFF ON ON ON ON Jumper OFF Pins 1-2 OFF ON OFF ON OFF ON OFF ON SCSI ID 0 1 2 3 4 5 6 7 SCSI Termination (Jumper on pins 11-12 enables active termination) Termination Power (Jumper on pins 15-16 enables termination power) Pins 3-4 OFF OFF ON ON OFF OFF ON ON Figure 3. Location of Jumper Blocks on Internal DAT2 Drives Settings for each jumper described in detail in the following pages. The default settings are: · · Terminator power is disabled. Active termination is disabled. 14 Installation Installing an Internal DAT24 Drive Enabling SCSI Termination Active SCSI termination is disabled as the factory default. If the drive is the only device on the SCSI bus, or if it is the last device on the bus, enable active termination by placing a jumper across pins 11 and 12. Terminator Power You can enable terminator power if needed for terminators or other SCSI devices through a jumper placement. The factory default for internal drives is that terminator power is disabled. To enable terminator power, place a jumper across pins 15 and 16, as shown in Figure 3 on page 14. Caution. If the jumper is installed, be careful not to short the TERMPWR signal to ground. The drive contains a terminator power fuse to prevent damage to drive components in case the terminator power is shorted. If terminator power is enabled and the SCSI cable is connected upside down, for example, this fuse may blow to prevent damage to the drive. If this occurs, the drive will no longer supply terminator power to the bus. To replace the fuse, return the drive to an authorized repair facility. Remote SCSI Address Selection Use pins 1 through 6 to select the SCSI address remotely. To do so, connect a remote SCSI ID switch to pins 1 through 6. Pins 1 and 2 configure SCSI ID bit 0. Pins 3 and 4 configure SCSI ID bit 1. Pins 5 and 6 configure SCSI ID bit 2. · · · NOTE: If you use remote SCSI ID selection, set switches 1 through 3 to the OFF position (see Figure 1 on page 11). Mounting an Internal DAT24 Drive You can install the internal DAT24 drive horizontally or vertically (on its side). Mounting the Drive in a 3.5-inch Drive Bay To mount the drive in a 3.5-inch drive bay, mount the drive using two M3.0 metric screws on each side of the drive. Do not use screws longer than 4 mm or you may damage the drive.
