Tools And Test Equipment; Figure 6.2 Indicating Revision Numbers - Fujitsu MAU3147RC Product/Maintenance Manual

Diagnostics and Maintenance
(1) Indicating revision number at factory shipment
When the disk drive is shipped from the factory, the revision number is indicated by deleting
numbers in the corresponding letter line up to the corresponding number with = (see Figure 6.2).
(2) Changing revision number in the field
To change the revision number because parts are replaced or other modification is applied in the
field, the new level is indicated by enclosing the corresponding number in the corresponding letter
line with bold line (see Figure 6.2).
When the revision number is changed after the drive is shipped from
the factory, Fujitsu issues "Engineering Change Request/Notice" in
which the new revision number is indicated. When the user changes
the revision number, the user should update the revision label as
described in item (2) after applying the modification.
