Sorry the rack forum seems to be offline.
I bought a used 2420 rack for home. I notice in the documentation which I found online for the rack there are rack clips (as dell calls them) for the back of rack to allow you to do cable management. If you haven't seen them they go into area were the PDU's sit.
I have looked on line for these clips but can't find anything related to them. I wonder if anyone else had had any luck at finding them or getting a part number or something they could share?
Thanks,
Andrew
