Description
MS60-CA Memory Module
The MS60-CA (Figure 1–1) is a double-sided 32 megabytes (Mbytes)
memory for VAXstation 3520/3540 systems. The MS60-CA has the
capability of performing dynamic random access (DRAM) single bit
error correction and double bit error detection. Similar to other MS60
memories, the MS60-CA can perform self-test and initialization of its
DRAM array.
Four MS60 memory modules can be installed in a VAXstation 3520/3540
workstation. With four MS60-CA modules installed, memory capacity of
128 Mbytes can be achieved.
NOTE
The MS60-CA memory module does not have battery backup
capability. Any VAXstation power loss destroys data stored in
memory.

Installation
This chapter describes how to unpack, inspect, and install the MS60CA memory module and RZ56 disk drive options for the VAXstation
3520/3540 workstation.
NOTE
It is the customer’s responsibility to back up software before
a Digital service representative arrives at the customer’s site.
This step is very important to ensure that data is not lost during
any service process. The customer should also shut down the
workstation software. Before installing options, confirm that the
customer has completed both of these tasks.

Unpacking and Inspecting the Options
When inspecting an option kit, look for external damage to the shipping
container, such as dents, holes, or crushed corners. If any damage is
apparent, write a note describing the damage on the packing slip before
proceeding.
Following antistatic procedures, carefully open the shipping container and
remove the contents.
Remove the option from its antistatic bag or packing materials and
inspect it for shipping damage. If any part in the option kit is damaged or
missing, notify the customer before proceeding.

Testing the System
Before installing any option, you should test the existing VAXstation
3520/3540 workstation to verify that it is running properly.

Installation 7

Testing the Present Configuration
Press the restart/run button on the control panel. This initiates the
power-up self-test.

VAXstation 3520/3540 Maintenance Guide and correct any problems
before continuing with the installation.
If the self-test succeeds, turn the power off and remove any covers as
necessary. Refer to Chapter 3 of the VAXstation 3520/3540 Maintenance
Guide for detailed instructions.

Testing the New Configuration
After installing an option, test the new configuration by pressing the
restart/run button. The workstation checks its new configuration and
performs a power-up self-test.
If an error code is displayed, check the cable connections. Run the powerup self-test again. If an error still occurs, follow the troubleshooting
procedures described in Chapter 2 of the maintenance guide.

Installing the MS60-CA Memory Module
Install the MS60-CA memory module in slot 5, 6, or 9 of the card cage. If

Troubleshooting
This chapter describes how to troubleshoot the MS60-CA memory module
and the RZ56 disk drive options by using self-test and system exerciser
diagnostics for the workstation.

MS60-CA Memory Module
The MS60-CA memory module uses internal diagnostics to perform
self-test and DRAM array initialization.

Self-Test Results
The results of the self-test, in addition to the screen message, are
indicated by the red and yellow LEDs on the front edge of the module. If
the yellow LED is on and the red LED is not on, the module has passed
the self-test. If the yellow LED is not on and the red LED is on, the
module has either failed or the test is not finished. If both LEDs are on,
the test has not started.
If the module failed self-test, replace the module. Refer to Chapter 4,
Removal and Replacement for instructions on how to replace the module.
For additional information on troubleshooting, refer to Chapter 2 of the
VAXstation 3520/3540 Maintenance Guide.

RZ56 Disk Drive
To troubleshoot the RZ56 disk drive, use the self-test and system exerciser
diagnostics for the workstation.
