Do not use any test equipment to check components on the PCBA. There are no user-serviceable components on the drive. DRIVE SETUP Drive setup for DLT 4000 tape drive includes the following: Set the SCSI ID for the drive (default = SCSI ID 5) Configure the drive to provide TERMPWR Set parity checking for the drive (default = parity checking enabled) If you want to change any of the settings, go to the applicable subsection;...
A jumper must be installed across Pins 9-10 (Remote ID Present pins) for the host to recognize any SCSI ID selections from this jumper block. Figure 2-1 DLT 4000 SCSI ID Jumper Location (Rackmount Version Shown) NOTES SCSI ID Jumper Block (J13)

2.2.3 Configure The Rackmount Drive for Parity Checking The default setting for DLT 4000 tape drives is to have parity checking enabled. If the system to which you are configuring the rackmount tape drive does not generate SCSI parity, there are two ways that parity checking can be disabled.
DRIVE INSTALLATION This section describes how to mount and secure the drive in the system. Figure 2– 5 shows the mounting locations and dimensions for the drive. Quantum DLT 4000 Tape Drive SCSI ID Pushbutton Power Switch Power Connector...
This connector is an internal connector so is not discussed in detail in this manual. The bezel connector pinout on the DLT 4000 tape drive (Model TH5XB-NP) is not compatible with any other DLT products. A flex cable adapter is available to connect these tape drives to a library/loader system that uses header pins for the bezel connection.
The three external connectors on the DLT 4000 tape drive that are discussed in this manual are the SCSI, power and optional loader connectors. Tabletop connectors are described in subsection 2.4.3. 2.4.1 SCSI and Power Connectors (Rackmount) Figure 2-6 shows the pin orientation for the 50-pin SCSI connector and 4-pin power connector located on the back of the tape drive.

The ANSI SCSI specification refers to mini-libraries as “medium changers.” In this chapter the term “mini-libraries” is used to describe these devices. The DLT 4000 supports block size of 1byte to 16 Mbytes. Disconnects from the SCSI bus are done at regular intervals during information transfer phases to allow other devices to access the bus.

The following apply to the DLT 4000 tape drive’s behavior at power-on and/or SCSI bus reset: When the Quantum DLT 4000 is powered up, all device SCSI lines are set to high impedance. The design of the DLT 4000 tape drive does not allow it to generate any spurious signals on the SCSI bus at power-on.
The DLT 4000 tape drive recognizes multiple, successive SCSI bus resets and SCSI bus resets of arbitrarily long duration. The tape drive recovers within the time limits specified above following the last SCSI bus reset. 5.1.7 Data Cache and Tape Write Interaction The Quantum DLT 4000 drive contains a data cache that buffers blocks (records) until they are written to tape.
The SCSI command descriptions that make up the rest of Chapter 5 contain detailed information about each command supported by the Quantum DLT 4000 tape drive. Fields common to many of the SCSI commands are supported as follows:...
