Expansion Unit Front View 16-Cartridge magazine 1 2 3 Magazine security lock Control panel 4 5 6 6 SHR-1194 Unlock /Open button Locked indicator Power switch In addition to its system control functions, the Expansion Unit has a 16cartridge magazine with a rugged random access robotic mechanism. The module robotics moves cartridges between the Pass-Thru Mechanism and any of the 16 cartridge storage locations.
1-4 Compaq TL881 Minilibrary System Users Guide The MiniLibrary Base Module The MiniLibrary Base Module (Figure 1–2) has one or two DLT 20/40 tape drives and a 10-cartridge magazine with a rugged random access robotic mechanism. The TL881 using one or two DLT20/40 series drives, also uses the DLTtape IV cartridges, which provide a native capacity of 20 GB per cartridge. All models can also read and write DLTtape III and DLT tape IIIxt cartridges.
Introduction 1-5 The Data Unit The Data Unit (Figure 1–3) has a 16-cartridge magazine, a random access robotic mechanism, and no tape drives. The module robotics, under control of the Expansion Unit, moves cartridges between the Pass-Thru Mechanism and any of the 16 cartridge storage locations. 1 2 3 4 5 Figure 1-3.
1-6 Compaq TL881 Minilibrary System Users Guide Drives With a standard SCSI interface, modules equipped with DLT 20/40 drives have a native data transfer rate of 1.5 MB/second, 3.0 MB/sec for two drives. The rates for compressed data are dependent on compression ratio, record size, data type, and other system parameters, but averages approximately 1:7. Internal Cabling Configuration The differential version of the MiniLibrary base module is wired in an independent-bus SCSI configuration.
Introduction 1-7 System firmware integrates all of the robotics of these system modules with that of the Pass-Thru Mechanism into a single high-performance library robotics system. Features There are a number of important external features to note about the Expansion Unit, the MiniLibrary Base Module and the Data Unit.

Chapter 3 Installation Installation Overview This chapter describes the complete MiniLibrary System installation process from planning and parts identification to mechanical installation, cabling, and configuration. Introduction There are three basic areas for installing a MiniLibrary System: Mechanical installation; cabling; and configuration. Mechanical installation consists of: ■ Assembling the Pass-Thru mechanism - the two-module version is factory assembled.
3-2 Compaq TL881 Minilibrary System Users Guide ■ Connecting the Expansion Unit to the Pass-Thru mechanism motor ■ Connecting the MiniLibrary Base Module drive SCSI buses to host SCSI interfaces ■ Connecting the Expansion Unit to a host SCSI interface ■ Terminating the buses properly Configuration consists of: ■ Using the Configure Menu to customize the configuration options to your particular application The remainder of this chapter describes each of these steps.
Installation 3-3 to help localize system failures. When installed, the motor drive assembly of the Pass-Thru mechanism is directly behind the Expansion Unit. Data Units and MiniLibrary Base Modules may be installed anywhere below the Expansion Unit, in any order. There may be a slight performance advantage in making the MiniLibrary Base Modules contiguous, but gaps are permitted. The size of a gap is limited by the fact that each gap must be bridged by some number of 7” Pass-Thru mechanism track sections.

Chapter 6 Diagnostics and Troubleshooting Diagnostics and Troubleshooting Overview This chapter describes the procedures for diagnosing platform problems and drive errors that can cause the MiniLibrary to malfunction. It also provides Fault Symptom Codes and Error Recovery Procedures to help restore operability. Diagnosing Problems There are two main types of problems that can cause the DLT MiniLibrary to malfunction or fail to perform correctly: platform problems and general drive errors.
6-2 Compaq TL881 Minilibrary System Users Guide General Drive Errors These errors usually result from a miscommunication between the drive processors or involve a mechanical malfunction. In most cases, these types of errors report an error message and an FSC to the control panel. The only exceptions are power supply problems and display malfunctions. The FSC can be used to determine a recovery procedure.

Appendix F Tape Drives and Cartridges Overview This appendix discusses: ■ Care and Handling of Cartridges ■ Care and handling of cartridges ■ Preparing cartridges for use ■ Adding and removing cartridges through the load port ■ Adding and removing cartridges through the storage array door ■ Using the tape drives ■ Removing cartridges from the tape drives Care and Handling of Cartridges CompacTape is a digital linear tape (DLT) that has been designed and formulated for use in DLT tape drives
F-2 Compaq TL881 Minilibrary System Users Guide Handling and Storage Guidelines ■ Do not carry cartridges loosely in a box or other container that exposes them to unnecessary physical shock. ■ Store each cartridge in its protective case until you select it for use in a tape drive or library. ■ Do not drop or bump the cartridge. This may dislodge and/or damage internal components. ■ Avoid unnecessary opening of the cartridge door; this may expose the tape to contamination or physical damage.
Tape Drives and Cartridges F-3 Checking a Cartridge for Damage If a cartridge has been dropped or if you have other reason to believe it may be damaged, inspect it carefully before inserting it into the library. Inspect the cartridge as follows: 1. Shake the cartridge and listen for any sound of a broken part (such as a reel lock). Any rattling noise is an indication that the cartridge has been damaged and must not be used. 2.
F-4 Compaq TL881 Minilibrary System Users Guide CAUTION: If the leader is out of position, do NOT use the cartridge; it can cause the drive takeup leader to fail. 1 2 3 4 7 5 6 8 SHR-1292 Figure F-2.
