Tossing up whether this is a Networking topic, but we'll start here.

Power supply in my active LB4m just died - while I had a spare, because I bought two switches, I am now obviously using said spare.

It appears I was using a Delta DPSN-300DB D - I'm guessing the D is the revision, or related to the revision. There are many DPSN-300DB power supplies on Ebay, some are marked D, some F, some H. Does anyone know whether they're all interchangeable?

Edit: Products - Networking Power - Delta Group is ... not helpful. Perhaps different fan specs, directions?
