Figure 1 shows the indicators, jumpers, and connectors on the TLZ07 tape
drive. Table 1 shows the default switch settings, and Table 2 describes the
light indications.
Table 1 SCSI ID / Option Selection Switch
Switch Default Setting
S1 - S3 SCSI ID Off - See Note
S4 Media Recognition
System (MRS) On = Disabled
S5 Parity On = Enabled
S6 Compression On = Disabled
S7 Off = Reserved for future use
S8 Self-test On = Enabled
Note
In a DEC 4000 system, the SCSI ID select cable is used instead of
jumpers. The SCSI ID jumpers are logically ORed with the SCSI ID
select connector pins. Set switches 1 - 3 off because the logic recognizes
a SCSI ID bit set if either a switch is on or the bit is set by the cable.
Media Recognition System
The media recognition system (MRS) is a quality standard for tapes. Cassette
tapes that meet this standard are labeled MRS or Media Recognition
System, and contain identifying information at the beginning of the tape.
2

TLZ07
When the media recognition system is enabled on the TLZ07 cassette tape
drive (S4 off), the TLZ07 drive reads the header information on the cassette
tapes to determine if the tape meets the MRS standard. Although it can read
any 4 mm cassette tape, the drive will only write to tapes that meet the MRS
standard. If the cassette tape does not meet the MRS standard, you will see a
write-lock error message on the console terminal.
When the media recognition system is disabled (S4 on), the drive will write to
any MRS tape as well as tapes that do not meet the MRS standard.

TLZ07
Installation
Caution
Static electricity can damage integrated circuits. Use the antistatic
wrist strap and antistatic pad found in the static-protective kit (ON
29–26246–00) when you work with the internal parts of a computer
system.
Before you begin the installation procedure, remove the bus continuity card
from the option storage slot into which you intend to install the tape drive.
Figure 6 shows the location of the bus continuity cards.
To install a TLZ07-MX tape drive in your system, perform the following steps:
1. Slide the TLZ07-MX mounting bracket assembly into the option storage
slot and push until the connector on the SCSI paddle card on the drive
mounting bracket engages securely into the backplane. Secure the
assembly by tightening the two captive screws. Figure 2 shows the location
of one of the screws. The second screw is located on the bottom drive
mounting bracket. Do not over-tighten the screws; 9" lbs is sufficient to
secure the drive. It is normal for there to be a slight gap between the
bracket and chassis.
2. Attach the SCSI ID cable to the OCP connector on the bezel assembly
(Figure 2).
3. Insert the tabs on the bottom of the bezel into the slots on the storage slot
(Figure 2).
4. Push in the top of the bezel, and tighten the Phillips screw (Figure 2).
5. Install a SCSI ID plug to the front of the bezel, making sure that the SCSI
ID number is not used by another device. The bezel is marked to show the
corresponding SCSI ID plug for each slot.
To add a TLZ07-MY tape drive to your system, perform the following steps:
1. Remove the mounting assembly as follows:
• Remove any SCSI ID plugs installed in the bezel.
• Loosen the Phillips screw at the top of the bezel, pull out the top of the
bezel, and carefully lift the bezel up and out from the storage slot to
expose the SCSI ID cables.

TLZ07
• Remove any SCSI ID cables from the OCP connector on the bezel
assembly.
• Loosen the two captive screws that secure the mounting bracket to the
chassis.
• Pull on the mounting assembly until it slides away from the chassis.
• Place the mounting assembly on the antistatic pad.
2. Connect the SCSI ID cable to the back of the drive (Figure 1).
3. Slide the drive into the mounting assembly.
4. Attach the SCSI and power cables to the drive. Figure 1 shows the location
of the connectors.
5. Secure the drive into the mounting assembly with the four mounting
screws provided. Two screws attach to the top of the assembly, and two
screws attach to the bottom of the assembly (Figure 3 shows the top of the
assembly). Make sure that the top front screw goes through the grounding
strip shown in the figure.
Caution
Failure to connect the grounding strip could result in data errors.
6. Remove the blank panel from the bezel (Figure 4).
7. Remove the blank flat plug(s) from the bezel (Figure 5).
8. Return the OCP connector board to the bezel.
9. Install SCSI ID plugs on the front of the bezel. Each drive must have an
unique SCSI ID number. Make sure that the drive that was installed prior
to this add-on procedure retains the same SCSI ID number that was used
previously. The front of the bezel is marked to show the corresponding
SCSI ID plug for each slot.
10. Slide the mounting bracket assembly into the option storage slot and push
until the SCSI paddle card on the drive mounting bracket engages securely
into the backplane. Secure the drive by tightening the two captive screws.
Figure 2 shows the location of one of the screws. The second screw is
located on the bottom drive mounting bracket. Do not over-tighten the
screws; 9" lbs is sufficient to secure the drive. It is normal for there to be a
slight gap between the bracket and chassis.

TLZ07
11. Attach each SCSI ID cable into the appropriate connector on the OCP
connector board on the bezel (Figure 2). The top connector corresponds
with the left storage slot, and the bottom connector corresponds with the
right storage slot. The bezel is marked to show the corresponding SCSI ID
plug for each slot.
12. Insert the tabs on the bottom of the bezel into the slots on the storage slot
(Figure 2).
13. Push in the top of the bezel, and tighten the Phillips screw (Figure 2).
