Get to the computer on the other side and activate the cooling system, then hit the button on the pole.
Enter the next hallway and sneak behind the android to take it down. Keep going until you reach the main area.

"ID Tag: If you head back towards the first room you entered in the area, you'll come across a poisonous hallway. Head into the side room to find the ID Tag on a crate.
From either server room, head inside the vent. Try to use the Access Tuner to get inside APOLLO, but the hacking mini-game game won't give you enough time to finish the puzzle.

Once activated, the core will rise and a door will open. Enter to watch a cutscene.
Turns out Weyland-Yutani is at it again, trying to preserve the Alien aboard the ship, despite the fact that it is no longer there. Those scum.
