I'm looking to connect two Thunderbolt displays to a single MacBook Pro. I've seen another thread here which mentioned hubs and display ports, but it seems this can be accomplished natively with the ports.

However, when I plug the second display into the first, the second one does not power on. I think the issue might be because the Thunderbolt displays are slightly different. One is a newer Thunderbolt which has the little "thunderbolt" icon on the video cord. The other is a little bit older and has a "video" icon on the video cord. The "video" Thunderbolt doesn't have a Thunderbolt port on the back, while the "thunderbolt" monitor does. Both screens will work independently, but when I plug the "thunderbolt" display into my MacBook and try to get the other to display by plugging the "video" cord into the thunderbolt port of the first monitor which on, nothing happens.
Does it sound like an adapter issue, or something I need to adjust via preferences or a software update?

That symbol you see is the Mini DisplayPort icon (https://support.apple.com/en-us/HT204149).
Apple has stated that Mini DisplayPort adapters won't work in a Thunderbolt chain.
