GS748T Switch Hardware Version ID

I have seen this question numerous times in the forum, but it is only answered when someone sends a picture that is not available to other forum users.  Why doesn't Netgear post some way for owners of the GS748T switch to identify the hardware version of the switch that they have.

I recently purchased a GS748T switch on Ebay that was advertised as a GS748Tv5 switch, but it appears that it is NOT v5 switch after all.  Before I contact the seller about this, I want to know what I'm talking about and make sure that this switch is indeed something other than a v5 switch.  How can I tell what hardware version my switch is?  It isn't marked anywhere on the device, and it does not show up anywhere in the browser based setup screens.
