DHW42-BA—Connect two H3101-00 loopback connectors

•

DHW42-CA—Connect two H4081-A loopback connectors

•

DHW42-UP—Connect two H3101-00 loopback connectors

To test the operation of the asynchronous communications option, enter the
following command at the console prompt.
>>>T EC 2
The test takes approximately 45 seconds to run.
If the system passes the test, install the external components.
If the system fails the test, the console terminal will display an error message.

7.3 SCSI ID Information
In a VAX 4000 BA42B-based system, each SCSI device must have a unique
SCSI ID number. In an RRD43 CD-ROM drive, the SCSI ID number is
determined by three jumpers (See Figure 7–2). When installing an RRD43 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
RRD43-EK CD-ROM drive option.
1. Determine the SCSI ID number to be assigned to the RRD43 CD-ROM
drive option. Typically, the RRD43 CD-ROM uses SCSI ID 4; however, the
system manager may prefer to make this decision.

9.4 SCSI ID Information
In any system, each SCSI device must have a unique identifier called the SCSI
ID number. In an RZ25L disk drive, the SCSI ID number is determined
by three jumpers. See Figure 9–1. When installing an RZ25L 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.

RZ25L Disk Drive Option 9–1

RZ25L Disk Drive Option
9.4 SCSI ID Information
The following procedure describes how to set the SCSI ID number on an RZ25L
disk drive.
1. Determine the SCSI ID number to be assigned to the RZ25L 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 console prompt on the system console terminal, enter the SHOW
CONFIG, SHOW DEVICE, or the SHOW SCSI command to 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. Place the drive on an anti-static surface with the HDA down, and the SCSI
connector toward you. Figure 9–1 shows the drive orientation.
4. Locate the SCSI ID jumper pins on the disk drive. The RZ25L disk drive
has two sets of SCSI ID jumpers. You can use either set, but use only one
of the two sets of jumpers to set the SCSI ID number. See Figure 9–1.
5. Position the jumpers for the SCSI ID number selected. Table 9–1 shows
the SCSI ID number and the corresponding jumper settings.

11.4 SCSI ID Information

11.4 SCSI ID Information
In any system, each SCSI device must have a unique identifier called the SCSI
ID number. In the RZ26, RZ26L, and RZ28 disk drives, the SCSI ID number
is determined by three jumpers. See Figure 11–1. When installing an RZ26,
RZ26L, or RZ28 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 RZ26,
RZ26L, or RZ28 disk drive option.
1. Determine the SCSI ID number to be assigned to the 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 console prompt on the system console terminal, enter the SHOW
CONFIG, SHOW DEVICE, or the SHOW SCSI command to 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 11–1.
4. Position the jumpers for the SCSI ID number selected. Table 11–1 shows
the SCSI ID number and the corresponding jumper settings.

14.5 Diagnostic Support

14.5 Diagnostic Support
The VAX 4000 BA42B-based systems provide diagnostic support that tests the
operation of a TZK10-HG or TZK11-HG option in the system.
Enter one of the following commands at the console prompt to test the
operation of the TZK10/TZK11:
>>>SHOW DEV
>>>SHOW SCSI
When the system is in the Digital services environment, you must install a test
tape in the TZK10/TZK11 tape drive.
If the system fails the test, the LED display on the back of the system unit
displays a code in the range A0 to A5(hexadecimal), and the console terminal
displays a hard error message containing the test mnemonic (SCSI).
