Physical Locations

Use the following illustrations to help you map a location code to a position on the server.
Figure 4. Front and rear views of the system unit
Figure 5. Memory module locations on the processor card (Un-P2-Cx)

Use the following illustration to map a node location when you are working with a multiple node installation. All of the nodes have the same location codes inside the system unit; only the serial number is different (Utttt.mmm.sssssss-).
