Installed reworked one-stop cards in I/O chassis for h1seih45, h1sush56, and h1susauxh56. Ran timing fiber for h1seih45's I/O chassis, connected timing fibers for h1sush56, h1susauxh56. Powered up I/O chassis, made sure timing sync'd up, then powered up computers. All three computers show the I/O chassis' cards. Dolphin network is currently unplugged from h1seih45 and h1sush56. NOTE: no AI/AA chassis or binary cables are connected to the I/O chassis.
