 ====System Component Views and Identification====
-The Limulus Cluster Workstation is a desk-side high performance machine. The mobile case is pictured below. It has two side doors and a removable front panel. To power button, indicator lights, and USB ports are across the top. Immediately below, there is a removable SSD drive cage.
+The Limulus Cluster Workstation is a desk-side high performance machine. Views of the case are pictured below. Design detail are available on the [[ functional_diagram| Functional Diagram ]] page.

+The case has two side doors,a removable front panel, and is on castors for easy movement. The power button (for the main motherboard), indicator lights, and USB ports are across the top. Immediately below, there is a removable SSD drive cage.
-The following view is with all panels and doors removed.

+The following view is with all panels and doors removed.There are six HDD bays across the inside top of the case. An additional two (or more depending on model) SDD bays are available on the font. The three removable compute nodes are visible on the front (connected by blue Ethernet cables), The main board (login, node management, etc.) is toward the back of the case above the power supply at the bottom. The internal Ethernet switch and power control relays are located above the power supply and below the main motherboard,

+A full front view shows the three compute nodes. All motherboard connections, other than power are from the exposed motherboard back panel. Each blade has a plugable power connector that automatically seats itself when the blade is inserted. See [[ limulus_compute_blades| Limulus Compute Blades ]] for a detailed descriptions of the blade design. The white fan is the back-of-case exhaust fan seen on the side image above.
-Back of case

+Networking cables can be seen on the back of the case. For the 25-GbE models, the three dark sfp28 cables are from the compute nodes and connect to a four port NIC on the main motherboard. This NIC serves a 25-GbE switch. Once port of the card is unused and can be uses to present the internal 25-GbE network to the outside of the case. This port can be used for a LAN connect or for internal network expansion.
+The 1-GbE network on the main motherboard (blue cable) connects to the internal 1-GbE network through the specialized two slot PCI card slot adapter Note: There is no PCI connection, the part uses the slot to present two internal 1-GbE switch ports to the outside of the case. One port is used to connect the 1-GbE port from the main motherboard to the internal 1-GbE network (blue cable). The second open port can be used to expose the internal 1-GbE network to other systems.
+A 1-GbE LAN connection is available from a separate NIC installed on the main motherboard (silver slot with open port on the image).
+See the Limulus [[ functional_diagram| Functional Diagram ]] for more networking details.
+If used, video card outputs are presented on the back of the case.
+Finally, there is a single power supply (redundant option available) with a single power cord. All power for the Limulus is provided by the power supply. There are no other power cords required.
