 ====The Case: ====
-The case has two doors on both sides and a removable front bezel. The front bezel can be "popped" off by opening one (or both) of the doors and pulling the bezel forward. Behind the bezel you will find the three node blades. The blades are placed behind the bezel to provide protection and allow limited access (under normal conditions you will not need to access the blades). There are also six removable (not hot swap) 3.5-inch drive bays across the top on the inside. Depending on the model, there may also be user-accessible removable SSD drives (also not hot swap). Local LAN port and Video are labeled on the back.  (Note: On AMD Systems, the video port on northerner board is non-functional.)

 The worker nodes are on blades that are behind the bezel. Blades are removed by turning off the blade power (see below), removing the cables, unscrewing the captive bolts (top and bottom), and pulling the blade out using the captive bolts. The blade positions are unique (the same blade must always be placed in the same slot, due to DHCP booting (HPC systems) or the attached HDFS drives (Hadoop systems)).  The blades have a number on the small power-supply on the back of the board.
-Node names begin with "n0" and continue to the total number of workers in the system. Typically, this is ''n0, n1, n2''. Looking at the front of the system with the bezel off, node ''n0'' is in the right most position. node ''n1'' is in the middle, and node ''n2'' is in the left most position and can be seen when the through the door.
