Documentation

SCSI ID Information
In any system, each SCSI device must have a unique identifier called the SCSI
ID number. In an RRD42 CDROM drive, the SCSI ID number is determined
by three jumpers. See Figure 2. When installing an RRD42 CDROM drive in
a system, set the SCSI ID jumpers to a value that is not used by any of the
other SCSI devices in the system. See your system documentation for more
information about the SCSI bus.
The following procedure describes how to set the SCSI ID number on an
RRD42 CDROM drive option.
1. Determine the SCSI ID number to be assigned to the RRD42 CDROM drive
option. Typically, the RRD42 CDROM uses SCSI ID 4; however, the system
manager may prefer to make this decision.
2. At the console prompt on the system console terminal, enter the SHOW
DEVICE command. This will list the SCSI ID numbers for the existing
devices in the system. Verify that you are using a number that is not
currently assigned to another device.
3. Locate the SCSI ID jumper pins on the CDROM drive. See Figure 2.
4. Position the jumpers for the SCSI ID number selected. Table 1 shows the
jumper settings for each SCSI ID.
5. Position the jumper wires for parity. See Figure 2.

Figure 10 shows a bezel insert being removed for mounting the drive in
the right-hand position; remove the bezel on the left side if the drive is
to be mounted in the left-hand position.

Preparing to Install an RRD43 in the Left-Hand Position in a Model 40, 80, 85,
90, 95 System Before you install an RRD43 CD-ROM drive option in the left
storage slot on the lower drive-mounting shelf, perform the following steps:
1. Attach the mounting bracket. Facing the front of the drive, the captive
screw should be on the right, and the four screws attaching the mounting
bracket to the drive should be attached through the series of bracket holes
that are closest to the front of the drive.
2. Open the drive cover on the front of the enclosure by pushing the latch,
and from the inside the enclosure, push out and remove the blank bezel
insert that covers the left storage slot on the lower drive-mounting shelf.

SCSI ID Information
In any system, each SCSI device must have a unique identifier called the SCSI
ID number. In an RZ24L disk drive, the SCSI ID number is determined
by three jumpers. See Figure 13. When installing an RZ24L disk drive in
a system, set the SCSI ID jumpers to a value that is not used by any of the
other SCSI devices in the system. See your system documentation for detailed
information about the SCSI bus.
The following procedure describes how to set the SCSI ID number on an RZ24L
disk drive.
1. Determine the SCSI ID number to be assigned to the RZ24L disk drive
option. Typically, the first RZ-series disk in a system uses SCSI ID 1, the
second RZ-series disk uses SCSI ID 2, and the third RZ-series disk uses
SCSI ID 3; however, the system manager may prefer to make this decision.
2. At the system console, enter the SHOW DEVICE command from console
mode. This will list the SCSI ID numbers for the existing devices in the
system. Verify that you are using a number that is not currently assigned
to another device.
3. Locate the SCSI ID jumper pins on the disk drive. See Figure 13.

MicroVAX 3100 Platform Options Supplement 21

4. Position the jumpers for the SCSI ID number selected. Table 4 shows the

SCSI ID Information
In any system, each SCSI device must have a unique identifier called the SCSI
ID number. In a TLZ06/07 tape drive, the SCSI ID number can be set with
jumpers or switches. See Figure 25.
Note
The SCSI ID jumper pins are logically ORed with the SCSI ID switches.
Setting a switch is equivalent to installing a jumper.

When installing a TLZ06/07 tape drive in a system, set the SCSI ID jumpers
or switches to a value that is not used by any of the other SCSI devices in the
system. See your system documentation for detailed information about the
SCSI bus.
The following procedure describes how to set the SCSI ID number on a TLZ06
/07 tape drive option.
1. Determine the SCSI ID number to be assigned to the TLZ06/07 tape drive
option. Typically, a TLZ06/07 tape drive uses SCSI ID 5; however, the
system manager may prefer to make this decision.

MicroVAX 3100 Platform Options Supplement 49

To set the SCSI ID number with the jumpers:
a. Locate the SCSI ID jumper pins on the tape drive. See Figure 25;
SCSI ID 5 is shown.
b. Position the jumpers for the SCSI ID number selected. Table 8
shows the jumper settings for each SCSI ID number.
c.

Verify that the SCSI ID switches are not set, because the logic
recognizes a SCSI ID bit set if either a switch is on or a jumper is
installed.

To set the SCSI ID number with the switches:
a. Locate the SCSI ID switches on the tape drive. See Figure 25.
b. Position the switches for the SCSI ID number selected. Table 9
shows the switch settings for each SCSI ID number.
c.

Verify that the SCSI ID jumpers are not installed, because the logic
recognizes a SCSI ID bit set if either a jumper is installed or a
switch is on.

Off

The default switch settings for the SCSI ID and option switches on the
TLZ06/07 tape drive are all off except for switches S4, S5, S6, and S8 which
are on.
Media Recognition System
The media recognition system (MRS) is a quality standard for tapes that is
supported by the TLZ07 tape drive. MRS is not supported by the TLZ06 tape
drive. Cassette tapes that meet this standard are labeled MRS or Media
Recognition System, and contain identifying information at the beginning of
the tape.
When the media recognition system is enabled on the TLZ07 cassette tape
drive (switch S4 on the SCSI ID and option switchpack set to 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,
with MRS enabled the drive will only write to tapes that meet the MRS
standard. If a write operation is iniated with MRS enabled and the cassette
tape does not meet the MRS standard, a write-lock error message displays on
the console terminal.
When the media recognition system is disabled (SCSI ID and option
switchpack, switch S4 on), the TLZ07 cassette tape drive will write to any
MRS tape as well as tapes that do not meet the MRS standard.
Installation
Before installing the TLZ06/07 tape drive option, the enclosure cover must be
removed. If you are installing the TLZ06/07 tape drive option in a MicroVAX
3100 Model 40, 80, 85, 90, or 95 system, the upper drive-mounting shelf must
also be removed. See the appropriate enclosure maintenance manual for these
removal procedures.

MicroVAX 3100 Platform Options Supplement 57

SCSI ID Information
In any system, each SCSI device must have a unique identifier called the SCSI
ID number. In a TZK-series tape drive, the SCSI ID number is determined
by three jumpers. See Figure 28. When installing a TZK-series tape drive in
a system, set the SCSI ID jumpers to a value that is not used by any of the
other SCSI devices in the system. See your system documentation for detailed
information about the SCSI bus.
The following procedure describes how to set the SCSI ID number on a TZKseries tape drive option.
1. Determine the SCSI ID number to be assigned to the TZK-series tape drive
option. Typically, a TZK-series tape drive uses SCSI ID 5; however, the
system manager may prefer to make this decision.
2. At the system console, enter the SHOW DEVICE command from console
mode. This will list the SCSI ID numbers for the existing devices in the
system. Verify that you are using a number that is not currently assigned
to another device.
3. Locate the SCSI ID jumper pins on the tape drive. See Figure 28.
4. Position the jumpers for the SCSI ID number selected. Table 10 shows the
jumper settings for each SCSI ID number.
The jumper wires on either side of the SCSI ID select jumpers are installed
by default. The jumper to the right of the SCSI ID select pins enables the
terminator power (TERMPWR). In the TZK10 drive, the jumper to the left of
the SCSI ID select pins enables parity. In the TZK11 drive, the jumper to the
left of the SCSI ID select pins is a Vendor/Product ID Select (VSEL) switch.
This jumper should be installed in a TZK11 that resides in a MicroVAX 3100
system. It should be removed if the TZK11 resides in system with an operating
system from a vendor other than Digital.
