PE1750 system board different part numbers

I have a number of PE1750 servers that have different part numbers for their system boards and their scsi backplanes. Here are the descriptions: J2573 PRINTED WIRING ASSY, PLANAR (MOTHERBOARD), PE1750, 533M, SHROUD 4F884 PRINTED WIRING ASSY, INTERFACE, BACKPLANE, 1X3, PE1650 P0247 PRINTED WIRING ASSY, INTERFACE, BACKPLANE, 1X3, PE1650, MULTI SHEET INSERTER P1348 PRINTED WIRING ASSY, PLANAR (MOTHERBOARD), PE1750, 533MSI My questions is, are there any differences between the different part numbers and are they compatible / interchangeable? What does the "MULT SHEET INSERTER", "MSI" and "SHROUD" refer to in the descriptions? Thanks for any help. -Mike
