Diagnostic Support

The MicroVAX 3100 platform systems provide diagnostic support that tests the
operation of a DHW41 option in a MicroVAX 3100 platform system.
Note

You cannot put the system in the Digital Services mode unless there is
a loopback connectrr (29-24795-00) connected to asynchronous modem
control port 2 on the back of the system unit.

DHW41-8

MicroVAX 3100 Plattorm Options

DHWA41

Enter the following command at the console prompt to put the system in the

Digital Services environment:
>»> SET DIAGENV 2

Connect a loopback connector to asynchronous port A on the back of the system
unit. The loopback connector you connect depends on the option variant as
follows:

DHW41-AA—Connect the H3101-00 loopback connector

DHW41-BA—Connect the H4081-A loopback connector

Enter one of the following commands at the console prompt to test the

operation of the asynchronous communications option:
>>> T 14
>>> T ASYNC

If the test passes, install the external components.

If the test fails, the LED display on the back of the system unit displays a
code in the range E0 to EE(hexadecimal), and the console terminal displays
a hard error message containing the test number (14) and the test mnemonic
(ASYNC) as shown in the following example:
?? 021 14 ASYNC 1280

Caution

Use only memory modules that are qualified by Digital.

To install an MS44 or MS44L memory option, follow these steps:
1.

Identify the connectors on the CPU module into which you must install the
MS44 or MS44L memory option. See the KA45 CPU System Maintenance
or the KA47 CPU System Maintenance manual for connector identification
and memory configuration information. On the CPU module, the memory
connectors are labeled: 1H 1L, 2H 2L, and 3H 3L. You install a memory
option in the relevant pair of connectors.
Caution

The connectors are keyed so that you can install the MS44 or the
MS44L memory modules only with the correct orientation. Do not force
the modules into the connectors with an incorrect orientation.

Insert the first memory module into its connector at an angle (see
Figure MS44-2).

Caution
Ensure that you insert the memory module fully into its connector

before you tilt the memory module.

Tilt the memory module towards the front of the enclosure (see
Figure MS44-2) until the metal locking clips on the connector lock the
memory module in position.

SCSI ID Information
In a MicroVAX 3100 platform system, each SCSI device must have a unique
SCSI ID number. When you install an RRD42-EK option, you must set the
SCSI ID of that device to an ID that is not used by any of the other SCSI
devices in the system. See Table 2-3 in the KA45 CPU System Maintenance or
the KA47 CPU System Maintenance manual.

To set the SCSI ID of the RRD42-EK option, follow these steps:
1.

Locate the SCSI ID jumper wires on the back of the RRD42-EK option (see
Figure TZK10-2).

Determine the SCSI ID number that you want to assign to the RRD42-EK
option.
Note

When the system is in console mode, you can use the command SHOW
CONFIG to view the SCSI ID numbers that the existing devices in the
system use.

3. Position the jumper wires for the SCSI ID number that you want.
Table RRD42-1 shows the SCSI ID numbers and the jumper wire

combinations that correspond to these numbers.

SCSI ID Information

In a MicroVAX 3100 platform system, each SCSI device must have a unique

SCSI ID number. When you install an RZ24-EH option, you must set the SCSI
ID of that device to an ID that is not used by any of the other SCSI devices in
the system. See Table 2-3 in the KA45 CPU System Maintenance or the KA47
CPU System Maintenance manual.

You set the SCSI ID of the RZ24-EH option as fullows:
1.

Locate the SCSI ID jumper wires on the RZ24-EH option (see
Figure RZ24-2).

Determine the SCSI ID number that you want to assign to the RZ24-EH
option.

Note

Whe.: the system is in console mode, you can use the command SHOW
CONFIG to view the SCSI ID numbers that the existing devices in the
system use.

3. Position the jumper wires for the SCSI ID number that you choose.
Table RZ24-1 shows the SCSI iD numbers and the jumper wire
combinations that correspond to these numbers.

SCSI ID Information
In a MicroVAX 3100 platform system, each SCSI device must have a unique

SCSI ID number. When you are adding a SCSI device to an existing system,
you must set the SCSI ID of that device to an ID that is not used by any of
the other SCSI devices in the system. See Table 2-3 in the KA45 CPU System
Maintenance or the KA47 CPU System Maintenance manual.
To set the SCSI ID of the TZ30-EL option, follow these steps:
1.

Locate the SCSI ID switches on the right side of the TZ30-EL option (see
Figure TZ30-2).

Determine the SCSI ID number that you want to assign to the TZ30-EL

option,
Note

When the system is in console mode, you can use the command SHOW

CONFIG to view the SCSI ID numbers that the existing devices in the
system use.
