The following examples demonstrate how to read the serial number on the

modules.

86ML8712020175_ This module was manufactured in December (12) of

1987 (87). This unit is not compatible with the 545/555/575 CPU, because it

was manufactured prior to January, 1988 and the letter G (designating that

a modification occurred) does not appear at the end of the serial number.

020175G This module was manufactured in December (12) of

1987 (87). This unit is compatible with the 545/555/575 CPU, because it was

manufactured prior to January, 1988 and the letter G (designating that a

modification occurred) appears at the end of the serial number.

86ML8801

041324_ This module was manufactured in January (01) of 1988

(88). This unit is compatible with the 545/555/575 CPU, because it was

manufactured in January, 1988. (The letter G is not required if the module

was manufactured in January, 1988 or later.)

NOTE: The current serial number format is different from the format shown

in Figure B-1. Any module with a serial number that does not begin with

“86” is compatible with the current 545/555/575 CPUs.
