7.3 SAM Diagram and Face Plate Layout
The following figure shows a block diagram of the overall SAM architecture and Figure 7-2 on
page 131 shows the face plate layout.
The SAM has these interfaces:

Four 10/100Base-T Ethernet links
— One link to each system controller and switching blade (2)
— One link to the redundant SAM
— One link to the face plate

One Ethernet link, failover management status signals, and one IPMB branch or
segment to the other SAM
