Yes, the HDMI stacking ports are separate from the 10gb SFP+ ports where you would create lags. The family of products for Dell PowerConnect 55xx. The family will include four platforms: • 24 GE ports + 2 10G SFP+ + 2 10GE stack ports (HDMI)  • 24 GE ports + 2 10G SFP+ + 2 10GE stack ports (HDMI) + PoE  • 48 GE ports + 2 10G SFP+ + 2 10GE stack ports (HDMI)  • 48 GE ports + 2 10G SFP+ + 2 10GE stack ports (HDMI) + PoE   NOTE:  SFP+ ports are backwards-compatible with supported 1G SFP transceivers.  As far as the 1gb SFP transceivers for the 8024F I do not see that available as a purchase.  You might as a Sales Representative on the availability of the transceivers for the 8024F
I am looking to redo my network as follows: 2 x 8024F (Stacked with 4 Ethernet Stack links) 3 x 5548 (Stacked via HDMI)  Will I be able to use the 10gb ports on the 5548's to create LAG's to the 8024's?  I don't see anything in the manuals to say that I can't but I recently read something online where someone was saying that it is either / or on the HDMI and 10gb ports, you can't use both at same time?  I don't own this equipment yet, otherwise I would just try it myself. Also, I have seen references that the 8024F will take 1gb SFP transceivers as well as 10gb SFP+ transceivers.  Any idea what the part numbers are for the 1gb SFP transceivers? Thanks, Jeff
