Recently we have acquired a nice Dell FPM185 KMM without the mounting rails. Using the Dell Rails Matrix PDF:
We noted that the FPM185 was listed with "-" as the rail identifier. A set of ReadyRails II A7 1u rails were mounted but we noted that the KMM needed "slide-in" style rails, not the "drop-in" mounting the A7 set provided.
What are the rail types needed for this KMM? What are the part numbers and where can we purchase them? If they're proprietary, why include them on the rails matrix sheet with "-"? Additionally, are there any universal rail sets that will work with this KMM?
Thank you!
