6.2.2 Revision number

The revision number of an optical disk drive is represented with an alphabetic
character and a single-digit number. The revision number is shown on the revision
label attached to the drive. For example, Figure 6.1 shows the revision label
format.

Figure 6.1 Revision label

(1) Revision number indication

When the drive is shipped, the revision number is indicated by deleting the
numbers up to the corresponding number on the line of alphabetic characters.
(Each number is deleted with double lines =. See Figure 6.2.)

(2) Changing the revision number on site

When the revision number is changed on site because of parts replacement or
modification, the new revision number is indicated by circling the number on the
line of alphabetic characters. (See Figure 6.2.)

When a revision number is changed after shipment, Fujitsu issues
"Revision Number Change Request/Notice" to indicate the new
revision number. The user must update the revision label as
described above when changing the revision number.
