Set the wall switches to match the Auxiliary Lines clue on the AUX Disk. Line 1 has one painted stripe beside it, Line 2 has two, and Line 3 has three. Lines 1 and 2 run right to left; Line 3 runs left to right. Each line's light turns green when it's right.

Where it is

It's in the AUX room in the north-west corner of the lower floor of SWDP – Different (Part 6, Chapter 15). Open it with the AUX Key from the valve panel locker (code 0825).

One guide gives this exact switch order. The others only explain how to read the clue. Load the AUX Disk into the room's computer to check against your own game. Lines 1 and 2 start from the wall facing away from the computer.

When all three lights are green, go back up to the Control Room for the second round of valve panel commands.
