either a five- or six-digit warranty configuration number or a
stand-alone two- or three-digit configuration number as
follows:
Digit 1 - Last digit of shipment year.
Digits 2 and 3 - Shipment month.
Digits 4, 5, and 6 - Configuration number.
The configuration number identifies the version of the product.
New configuration numbers usually accompany changes in
the last two characters of the CLEI code.
The configuration number can also be found on a small bar
label that also contains the Julian date code. The configuration
number appears as either a stand-alone CFG xx number or as
a 15-character number comprised of the part number and a
3-character extension. For example, the number
150-2404-15-x03 is comprised of the part number and an x03
configuration number. This gummed label may be attached to
the PC board or to the front panel.
