A-4 viii 1 ------------------------------------------------------------ TLZ06 Cassette Tape Drive Product Description 1.1 Overview The TLZ06 cassette tape drive provides you with high capacity, off-line data storage. Depending on the 4 mm data cassette tape used, the unit can typically store: Tape Type (see NOTE 1.) No Compression Compression TLZ04-CA (60 m) 1.3 GB 2.6 GB TLZ06-CA (90 m) 2.0 GB 4.0 GB (see NOTE 2.) ------------------------------------------------------------ NOTE ------------------------------------------------------------ 1. The TLZ06 is compatible with TLZ04 (60 m) cassette tapes in the noncompressed mode only. 2. The 4.0 GB measurement is typical for a 2-to-1 data compression ratio, but the actual ratio is dependent on the data. ------------------------------------------------------------ The maximum time to backup (read or write) on a TLZ06 cassette tape in a continual (streaming) mode is system dependent. The efficient use of streaming mode is determined by your operating system. Please refer to your system software documentation. TLZ06 Cassette Tape Drive Product Description 1-1 1.1.1 System Support As of this printing, the TLZ06 drive is supported by VAXstation systems and DECstation systems. Your particular system must have a standard SCSI (small computer system interconnect) port, or a KZQSA (Q-bus to SCSI adapter). VAXstation systems can use the VMS or ULTRIX operating systems. DECstation systems use the ULTRIX operating system. Consult with your Digital sales support person for operating systems supporting this device. 1.2 Design Features The TLZ06 cassette tape drive uses state of the art technology. The TLZ06 cassette tape drive's design incorporates both digital data storage (DDS) and digital audio tape (DAT) recording technologies. 1.2.1 What is Digital Audio Tape (DAT)? Digital audio tape (DAT), such as TLZ06 cassettes, takes advantage of the TLZ06 tape drive's helical scan technology. This technology allows data to be stored diagonally on tape. As such, DAT allows more data to be stored on tape. Also, DAT recording minimizes ``crosstalk,'' providing you with more data integrity. 1.2.2 What is Digital Data Storage (DDS)? Digital data storage (DDS) uses a recording format that supports the use of digital audio tape for computer applications. The DDS/DAT format allows you to back up 2 gigabytes of data in approximately 3 hours minimum with no operator intervention. In addition, this format has three levels of error correction, which ensures high data integrity. ------------------------------------------------------------ NOTE ------------------------------------------------------------ Use of Non-DDS media may result in degraded drive performance and is not recommended by Digital Equipment Corporation. ------------------------------------------------------------ 1-2 TLZ06 Cassette Tape Drive Product Description 1.3 TLZ06 Models The TLZ06 drive is available as: · Model TLZ06-DA (tabletop) -- a compact external unit with a built-in power supply (Figure 1-1). · Model TLZ06-AA -- a 3 1/2-inch, half-height drive that mounts internally (Figure 1-2). · Model TLZ06-BA -- consists of a 3 1/2-inch drive in a 5 1/4-inch, half- height form factor allowing the drive to be mounted internally (Figure 1-2). · Model TLZ6L-AA -- a 5 1/4-inch, full-height auto loader that mounts internally (Figure 7-1). · Model TLZ6L-DA (tabletop) -- an external unit with a built-in power supply. ------------------------------------------------------------ NOTE ------------------------------------------------------------ All the models have a drive buffer size of 1 MB of memory. ------------------------------------------------------------ TLZ06 Cassette Tape Drive Product Description 1-3 Figure 1-1 Model TLZ06-DA (Tabletop) 1-4 TLZ06 Cassette Tape Drive Product Description Figure 1-2 Model TLZ06-AA (3 ½-inch Chassis) and TLZ06-BA (5 ¼-inch Form Factor) TLZ06 Cassette Tape Drive Product Description 1-5 1.3.1 Checking Your Shipment for Model TLZ06-DA In addition to this manual, make sure that your shipment includes the following: · One TLZ06-DA tabletop cassette tape drive · One 50-pin to 50-pin SCSI signal cable (PN 17-01351-01) for drive to drive connections only · Power cable · One blank cassette tape (4 mm x 90 m), (PN TLZ06-CA) · One head cleaning cassette (PN TLZ04-HA) · SCSI terminator (PN 12-30552-01) If your shipment is incomplete, please contact your Digital sales representative. 1.3.2 Ordering Additional Cassettes To order additional blank cassette tapes and head cleaning cassettes, contact your Digital sales representative or DECdirect.

Read the following sections to complete the installation. 2.2 Shut Down, Halt, and Power Off the System If you are installing a TLZ06-DA tabletop cassette tape drive or TLZ6L-DA tabletop auto loader on a running system, have your system manager perform the following steps: 1. Shut down the operating system. 2. Halt the system. 3. Set all system power switches off. Installing the Tabletop Drives 2-1 2.3 Selecting the SCSI Address To familiarize yourself with the TLZ06 drive: 1. Refer to Figure 1-1 for the location of the buttons, switches, and connectors on the tabletop drives. 2. Note that all connections are made at the rear of the drive. Your system uses a SCSI ID switch (Figure 1-1) to identify, or address, the drive. The SCSI ID is factory set at 5. If you are installing the drive on a system that is already using SCSI ID 5, use any available SCSI ID. (You may have to consult your system manager.) To set/change the SCSI address: 1. Locate the SCSI address switch at the rear of the drive. 2. Select the SCSI address for the drive: · TLZ06-DA -- Press the + or - button until the desired address (0 through 7) appears in the window. · TLZ6L-DA -- Set the switches according to Table 3-1. ------------------------------------------------------------ NOTE ------------------------------------------------------------ If you are installing any other drive variant, refer to Chapter 3. Turn off all power before connecting the cables and the terminator. The drive must be turned off and then on for switch settings to take effect, or a SCSI bus reset must be received. ------------------------------------------------------------ 2-2 Installing the Tabletop Drives The tabletop drives provide two SCSI connectors to allow daisy chaining. Either connector can connect to the host computer or any SCSI device in a daisy chain. · If the tabletop is the last drive in the chain, a single interface cable is attached to one connector and a SCSI terminator (PN 12-30552-01) is installed in the other connector. · If the drive is within the chain, the interface cable from the preceding device is connected in one connector; an interface cable is also connected from the other connector to the following device. ------------------------------------------------------------ NOTE ------------------------------------------------------------ Make sure that the last SCSI device on the bus is terminated correctly. ------------------------------------------------------------ 2.4 Connecting a SCSI Signal Cable -- Drive to System If you are connecting a TLZ06-DA drive or TLZ6L-DA auto loader directly to your system, you should use the SCSI signal cable supplied as part of your system installation kit.

The following sections describe how to: · Handle and store tape (Section 5.8.1) · Write-protect tape (Section 5.8.2) · Insert and remove tape (Section 5.8.3) ------------------------------------------------------------ WARNING ------------------------------------------------------------ Always place the tape label in the recessed area on the cassette. Never place one label on top of another label. ------------------------------------------------------------ ------------------------------------------------------------ NOTE ------------------------------------------------------------ Use of non-DDS media may result in degraded drive performance. We recommend the use of Digital Equipment Corporation media. ------------------------------------------------------------ 5.8.1 Proper Handling of Cassette Tapes To ensure optimal performance from your cassette tapes, observe the following guidelines when handling them. · Avoid placing the cassette tapes near sources of electromagnetic interference, such as terminals, and video or X-ray equipment. Emissions from such equipment can erase data on the tape. · Keep cassette tapes out of direct sunlight and away from heaters and other sources of heat. · Store cassette tapes (and cleaning cassette) where the room temperatures are between 5 and 32°C (40 and 90°F). · Store cassette tapes in a dust-free environment where the relative humidity is 20 to 60% RH. 5-4 Using the TLZ06 Cassette Tape Drive 5.8.2 Setting the Write-Protect Tab on the Cassette Tape If you are using the tape to read or are copying from the tape, set the write- protect tab to write-protected. This disables writing to tape, and ensures that data will not be accidentally overwritten. Use a pen (NOT A PENCIL) to set the write-protect tab (Figure 5-1) to the desired position. Observe the following guidelines when setting the write-protect tab. · If you are reading data (copying from the tape), set the write-protect tab to write-protected. · If you are writing data, set the write-protect tab to write-enabled. · The write-protect tab position is shown on the front panel Write-Protect indicator. 5.8.3 Inserting a Cassette Tape into the Drive Insert the TLZ06 cassette tape into the drive with the cassette's write-protect tab on the right, facing you. Using the TLZ06 Cassette Tape Drive 5-5 6 ------------------------------------------------------------ Preventive Maintenance and Problem Solving This chapter describes preventive maintenance and problem solving for the TLZ06 cassette tape drive. Preventive maintenance involves periodic head cleaning. Problem solving is described in Table 6-1. Statistics show that over 90% of drive-related problems are associated with the media. Therefore, Digital Equipment Corporation strongly recommends that you follow the instructions for handling cassette tapes and cleaning the heads of the drive. 6.1 Cleaning the Heads This section shows you how to perform TLZ06 head cleaning. The heads are the components that physically read and write data to and from the media (in this case, a cassette tape). Digital Equipment Corporation recommends that you perform the head cleaning procedure about every 2 weeks, or after every 50 hours of drive usage. Under normal conditions, it should not be necessary to exceed this cleaning schedule. If a particular data cassette causes problems, try changing to another data cassette. Preventive Maintenance and Problem Solving 6-1 ------------------------------------------------------------ CAUTION ------------------------------------------------------------ Never attempt to clean the heads in a manner other than described herein. Doing so will void the product warranty. ------------------------------------------------------------ To clean the heads, use the head cleaning cassette as follows: 1. Press the power switch ON to apply power to the drive. 2. Insert the head cleaning cassette (PN TLZ04-HA) into the drive. 3. With the head cleaning cassette inserted, the drive automatically executes head cleaning. The drive ejects the head cleaning cassette after approximately 30 seconds. 4. Locate the card enclosed with the head cleaning cassette. Place a check mark on the card every time you use the head cleaning cassette. Under normal conditions, the head cleaning cassette is used for about 25 cleanings. Additional cassettes are available from your Digital sales representative or DECdirect. If the head cleaning cassette has been overused, both the Cassette and the Write-Protect LEDs will flash. Press the eject button to remove the cleaning cassette. No cleaning action will have occurred. 6-2 Preventive Maintenance and Problem Solving 6.2 Problem Solving Table 6-1 describes drive problems and possible solutions. Table 6-1 Problem Solving ------------------------------------------------------------ Symptom Probable Cause Possible Solution ------------------------------------------------------------ Unable to back up or copy data to cassette tape. Cassette write-protected. 1. Set write- protect tab on cassette to write- enabled. No tape in drive. 2. Insert tape. Write-Protect LED flashes amber Excessive tape errors.

It is packaged in an industry standard 5.25-inch full-high form factor with an embedded TLZ06 tape drive. The TLZ6L auto loader model is not a field upgrade option for the TLZ06 tape drive; it must be purchased as a single unit. With a 4-cartridge magazine, the TLZ6L auto loader provides up to 16 gigabytes of storage. With an 8-cartridge magazine, the TLZ6L auto loader provides 32 gigabytes of storage; and with a 12-cartridge magazine, it provides 48 gigabytes of storage. 7.2 Indicators The TLZ6L auto loader has four LED indicators. The labels for these LED indicators come with the auto loader. They are provided in four languages: English, French, German, and Spanish; and two orientations: vertical and horizontal. Choose your labels and place them on the bezel as shown in Figure 7-1. (The dot matrix display also supports the same four languages.) The Data Compression LED is lit when data compression is enabled on the TLZ06 tape drive. Both the Data Compression LED and the LED to its right flash rapidly when a loader fault occurs. The Reserved LED is reserved for future use. The Write Protect and Cassette LEDs are described in Chapter 5, Using the TLZ06 Cassette Tape Drive.

The dot matrix display shows two types of messages: activity and status. 7.3.1 Activity Messages The dot matrix display has several activity messages: READ when the drive is reading, REWIND when it is rewinding, and so forth. 7.3.2 Status Messages The dot matrix display shows the current status of the auto loader when the drive is not active. Table 7-1 lists the status messages. Table 7-1 Status Messages ------------------------------------------------------------ Message Meaning ------------------------------------------------------------ READY n A cassette is loaded in slot n. The drive is ready to accept commands. EMPTY There is no magazine in the loader and no cassette in the drive. SEL SLOT A magazine is present in the loader, but there is no cassette in the drive. Use the select slot button to choose a slot to load. OPERATOR Same as EMPTY, but the drawer is open. DISMOUNT The drawer is open and the magazine has been unloaded. Remove the magazine or press the eject button to reinitialize the magazine. CHK MAG A cassette is loaded in the magazine incorrectly. This message alternates with the number of the slot you should check. 0 TAPES The magazine you just loaded has no tapes in it. ------------------------------------------------------------ TLZ6L Auto Loader 7-5 7.4 Operation The TLZ6L auto loader can be operated two ways: automatically or manually. It has two modes: Sequential and Random Access. 7.4.1 Automatic Operations During automatic operations, the TLZ6L auto loader can function in Sequential and Random Access modes at the same time. In Sequential mode, upon receipt of a SCSI unload command, the loader unloads the current cassette and automatically cycles to the next cassette in the magazine. It continues to unload and cycle to the next cassette until the last cassette has been unloaded. When this process is complete, the magazine stops to prevent accidental overwrite of data. Then the magazine may be unloaded. In Random Access Mode, the loader responds to all of the SCSI Random Access Commands. 7.4.2 Manual Operations Manual operations are performed from the front of the auto loader. To load a magazine, press the eject button. This opens the drawer and ejects any magazine that is in the drive. Then place the magazine in the mouth of the loader until the rollers engage the magazine. The loader automatically scans the magazine to make sure the cassettes are loaded correctly and to count the number of cassettes loaded. The loader displays the number of cassettes loaded. If a 4-cartridge magazine is installed, the drawer closes. If an 8- or 12-cartridge magazine is installed, the drawer latches in the open position. To load a cassette, press the slot button. Press it once to load the first cassette, twice to load the second cassette, and so on. If you make a mistake, continue pressing the slot button until the current state is shown on the dot matrix display. When you press the slot button, the loader displays the selected slot and allows some time for changes. Then the selected slot is automatically loaded and the drive becomes ready. To eject the magazine, press the eject button. This ejects any cassette that is in the drive, opens the drawer, and ejects the magazine. Then you can remove the magazine. 7-6 TLZ6L Auto Loader 7.4.3 Single Cassette Operation If a magazine is in the drive, eject the magazine. When the mouth of the loader is empty, you can load a single cassette in the drive. The drive should accept the cassette and load it. To eject the cassette, press the eject button. The cassette moves into the mouth of the loader. Then you can remove the cassette. 7.5 Switch Settings 7.5.1 Switchpack 1 Switchpack 1, or SW1 (Table 7-2), is located at the top of the drive.
