number

For some products the configuration number may contain 
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.
