Both Dell PowerConnect N4000 Series and Dell Networking PC8100 Series switches shares the same firmware image version (for example., N4000v6.1.0.1.stk). Dell Networking N4000 series switches can be stacked with Dell Networking PC8100 series switches with the entire stack required to run 6.0.0.8 or later firmware (6.1.0.1). Dell Networking PC8100 series switches can support both 5.x and 6.x firmware versions, but Dell Networking N4000 can support only 6.0.0.8 and later firmware versions (6.1.0.1) Hope this helps. -B
Hi! Within the last days, the Dell PowerConnect 8100 did disappear from the Dell website and now, the M4000 series with the same features are presented.  Is it just a rename, or do these devices differ in any way? Can the M4000-firmwares be used on 8100 switches in the future?  Thank you Regards, Stril
