It is not unusual to see a different part number on the module we shipped you when comparing it to the part number you ordered online. The part number you see on-line is a reference number so that we can connect the correct module to the correct system. Some modules have similar specifications, but, do not work in all systems.
When you order by advanced search online, you are shown the “external” part number CTxxxxxx. The part number that you see on your module is the actual module base part number CTxxxxxxxxx.xxx. If you order by advanced search or system information, the external part number is referenced in your packing list. The two cross-referenced part numbers refer to the same module.
