Functional Description

The SAM1620-D has a high-density 220-pin socket for the ShMM-1500R device and front
panel connectors for the serial console, Ethernet, and alarm signals of the mezzanine. The
dual-IPMB interface from the mezzanine is connected to the dual IPMBs in the backplane.
The SAM1620-D includes several on-board devices that enable different aspects of shelf
management based on the shelf management mezzanine. These facilities include I
based hardware monitoring/control and GPIO expander devices.
