The part number I have listed for the rail kit is : MfgPart#8K3MP Dell SKU#770-BBGY. I could not find this listed on the Dell accessories site, but your sales rep should be able to get you a quote on this part number. Cheers
After searching all over the Dell site and Google, I can't find this information.  Maybe I'm just off today, but can someone give me a link to and part number for the correct rail kit for PowerConnect N3048 switches.  Specifically they need to be mounted on two post racks. Thanks, Ralph
