I have a BCM r3 with 2 expansion modules and a POE switch. My customer has a 4x16 card they want to reuse. I don't have a spare 4x16 card to test. Where does the dn range start. In the book, the DSM 32 starts at a different dn than the 4x16. So, I don't think I can use the DSM 32 to test. I believe my dns should be 253 to 268. Thank you.
