Genius comments: You need to smash the orange power core things to lower the shield at the 1st one.
You need to stand at the right position to not get knocked away at the 3rd one, or use PvP trinket.
You need to use the consoles in the right order to lower the shield at the 4th one.
You can walk in solo and get (most of) these briefings. All you have to fight are the single adds at the shields.
We would like to thank Clarinetta for additional information and all screenshots.
