The SAM is the center of the IPMI network; hubs are the center of the Base Interface network.

The SAM connects to all slots in the shelf and monitors and reports on the content of the

AXP1620. The SAM collects environmental data from sensors within the shelf and can assist

high availability software to determine when a failover is necessary due to hardware removal or

environmental changes, such as an over-temp condition.

The SAMs contain the Shelf Management Controller (ShMC) which polls all devices resident to

the shelf and collects the FRU data records for all the components. The SAM also manages

non-IPMI devices for the shelf and performs environmental monitoring of the temperature and

voltage. Using the PICMG 3.0 standard, the SAM is able to power off and reset slots for hot

swap capability.
