Rack tip

If you have space for two PDUs and you put one on each side of the rack, you will have no separate space for network cables and you'll get interference. If you put those two PDUs on one side of the rack, you'll put it on the wrong side and your power cords will interfere with your network cables. If you put those two PDUs on the correct side of the rack, you'll find that racking new items is a pain because the cords block the post holes on that side.
