Functional Description

The SAM has a high-density 220 pin socket for the shelf management mezzanine (ShMM)
device and front-panel connectors for the serial console, Ethernet, and Telco alarm signals of
the mezzanine. The dual-IPMB interface from the mezzanine is connected to the dual IPMBs
in the backplane.
The SAM includes several on-board devices that enable different aspects of shelf management
based on the shelf management mezzanine. These facilities include I
monitoring/control and GPIO expander devices.

IPMB Connectivity

The IPMB is a dual radial topology. Each IPMC in the shelf connects to both SAMs for a
redundant IPMB.
