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 the CD server using a
command similar to that shown in Example 3–12 (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 3–12).
5. Issue the ATTACH command similar to that shown by
5
to enable
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 there is a
patch for that revision. 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 4.60 and the
EEPROM rev. is 4.10 (see
9
). A "yes" response is given. For CPU 06
the patch revision is 4.60 and the EEPROM revision is 4.60. Therefore,
the choice is made not to patch this EEPROM.
10. Test 3 determines what sections of the EEPROM need updating (see
10
).
