Sam and I, with much help from Richard, Filiberto, and Carl, have populated the two racks for the Single Arm Installation.  For the corner, the chassis are in, and the internal wiring is all hooked up.  At the end, most of the chassis are in, but Rolf is using the IO Chassis, and two binary chassis for some testing in the computer room, so those parts are not yet installed.  All of the cables are, at least, attached at one end, waiting for the IO chassis, or Binary chassis.  We just finished making the field cables that we need to test, and we will start testing this morning.
