All Sun Microsystems parts are known by at least two numbers, the X-Option number and the Part number. The best way to find out what part you have is the BarCode. Every part that Sun Microsystems sells has a Sun bar-code. This bar-code has both the part number and serial number of the part. (The X-Option number is not located on the part.)
