Service manual

1. Turn the lower key switch to Update.
2. Load the latest diagnostic CD in the CD drive. The CD is labeled 6000_
DIAG_x where x is a letter revision.
3. Boot the VAX Diagnostic Supervisor from a CD server using a command
similar to that shown in Example 4–13 (see
3
).
Alternatively, you could boot the supervisor from some other disk,
perform the appropriate ATTACH commands, and then use the VAX/DS
command SET LOAD to load EVUCA from the CD server. If you have
already copied the latest diagnostics to a local disk, run EVUCA from
there.
4. At the DS> prompt, type LOAD EVUCA (see
4
in Example 4–13).
5. Issue the ATTACH command similar to that shown by
5
to enable the
VAX/DS access to the CPUs on the system.
6. The CPUs are selected, TRACE is set, and EVUCA is started (see
6
).
7. Test 2 of EVUCA selects the correct patch file for the system being
patched.
7
. A carriage return is the appropriate response. (Test 1 is
for Manufacturing Automated Verification System use.)
8. After loading the file, EVUCA identifies the ROM and EEPROM
revisions of each CPU in the system and reports whether that revision
has a patch. CPUs at nodes 1 and 2
8
have no patches.
9. When a patch is found, EVUCA asks the operator whether the patch
should be applied. For CPU 05 the patch image found is 2.02 and
the EEPROM revision is 2.00. A "yes" response is given (see
9
). For
CPU 06 the patch revision is 2.02 but the EEPROM revision is 2.02.
Therefore, the choice is made not to patch this EEPROM.
10. Test 3 determines what sections of the EEPROM need updating.
