Quick answer
This is the R&D server-room cable puzzle, also called Routing Power. It is separate from the miniature circuit-board puzzle. Identify cabinets by their Greek letter and two-digit number.
How power routing works
One player follows the active blue node and cable; the other moves to the next cabinet. Wait for the charge before continuing. Yellow nodes have already been used in the current chain: do not try to branch from one again.
The unlabelled starting point beside ENERGY REBOOT is called Start below. You are not looking for a cabinet labelled GEN. Each battery’s markings tell you which cabinets must be visited, from top to bottom; each route finishes at Ψ07.
The three battery routes
Battery 1
Start → Ψ01 → Ψ04 → Ψ02 → Ψ03 → Ψ07
Battery 2
Start → Ψ01 → Ψ04 → Ψ02 → Ψ03 → Ψ06 → Σ04 → Σ03 → Ψ08 → Δ01 → Δ03 → λ02 → λ03 → λ01 → Ψ07
Battery 3
Start → Ψ01 → Ψ04 → Ψ02 → Ψ03 → Ψ06 → Σ04 → Σ03 → Σ01 → Σ02 → Ψ08 → Θ03 → Δ02 → Δ03 → λ02 → λ03 → λ01 → Ψ07
Check the actual cabinet characters carefully. Ψ, Σ, Θ, Δ and λ can resemble ordinary letters from a distance.
Colored doors and resets
| Cabinet | Access opened |
|---|---|
| Σ03 | Red door |
| Σ02 | Green door, reached from inside the red area |
| Δ03 | Blue door |
After a battery charges, use the two reset levers beside ENERGY REBOOT before starting the next route. Take one lever each and pull both fully down. Completed battery stages remain charged; the reset clears the current generator chain.
If you make a routing mistake, reset the chain and repeat that battery’s route. If Ψ07 does not advance the puzzle, check which battery is active and whether the previous cabinets have finished charging before trying the endpoint again.
The batteries are done, but the elevator will not open
Return to the office desk and pick up the data tape beneath the yellow note. Finish all three batteries, take the tape, then head back to the elevator. Solving the electrical route alone is not the last action.
