Power Strips
Each power strip is divided into outlet groups. Each outlet group has four outlets
(sockets). The outlet groups are divided into two sets: odd and even. The odd outlet
groups are 1, 3, 5, 7, and 9. The even outlet groups are 0, 2, 4, 6, and 8. The odd
outlet groups receive their power from one AC input and the even outlet groups
receive their power from the other AC input.
The power strips have a power indicator LED for each outlet group.
