Detailed Logical Diagrams
Use detailed logical diagrams when it is important to show the details of the ServerNet
links and routers. The X or Y fabric is represented by a collection of circles and lines
that represent individual routers and ServerNet links.
This figure is a detailed logical diagram of typical two-processor systems, one using
ServerNet router 1s, the other using ServerNet router 2s. It shows that for components
using ServerNet router 1, the slots housing the SEBs have one connection to the PMF
CRUs. For components using ServerNet router 2, the slots housing the MSEBs have
two connections to the PMF CRUs.
