Hi, I didn't think Dell supplied any CWDM optics. Anyway, I've managed to borrow some optics to test with and they are working fine. CWDM does work on these switches.. Peter
Hi, I'm trying to get CWDM working between two sites in London on Dell Powerconnect 6224 and a 6248. I've got the 2x 10GB SFP+ modules in the back of both and some tuned SFP+ CWDM optics which are coded for dell. I get a link on both sides however can't get any proper connectivity working. Another post  has suggested that they have had CWDM working with these switches before.
