6.2.2Revision 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 MCE3130SS revision label format.

(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.)

NOTICE

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.
