There are three different lengths of 2-wire, 12 VDC power cables. The two shortest
cables go to the fan that you removed in Step 6. The two longer cables go to the
three remaining fans removed in Step 8 and Step 9. The remaining cable goes to
the power connector on the backplane.
These cables are color-coded. If you use an incorrect cable to connect a fan or the
backplane, then you will be unable to make one of the other connections. To help
with reconnecting the cables, write down which colored cable goes to each fan.
