 ====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.)

 ====Login Node (Main Node): ====

 ====Networking: ====
-All systems have a 1 GbE network. All administrative daemons and shared file systems (NFS) are assigned to this network. The login node acts as a gateway node (i.e. it has an external LAN connection and an internal cluster network connection). The LAN port (as labeled on the case) is set to use DHCP. The internal cluster 1 GbE network uses 10.0.0.0/24 addresses (the login node is 10.0.0.1; the nodes, n0, start as 10.0.0.10 and are sequential). The login node is connected to this network by the short blue Ethernet cable on the back of the unit. This cable connects the login node to the internal 1 GbE switch.

 The internal Ethernet switch (as seen inside the case above the power supply) connects to the internal cluster network. In addition to the blue cable connected to the login node, one additional external cluster Ethernet port is available on the back of the unit for expansion (i.e. a cluster NAS or more nodes).

 ====Adaptive Cooling and Filters: ====
-The nodes have adaptive cooling. There are two intake fans underneath the worker nodes pushing air up into the nodes from underneath the case. The speed of the intake fans will increase or decrease depending on the node processor temperatures. Note that all intake locations on the case have magnetic dust filters (including the bottom of the case). In dusty environments, these filters will become dirty and can adversely affect the ability of the fans to move air through case. It is recommended that you check and clean these filters regularly. They can be easily cleaned with water. See [[Adaptive Cooling|Adaptive Cooling]].
