Shelf Management Alarm Module
7.1 Overview
This chapter describes the AdvancedTCA Shelf Management Alarm Module, hereafter known
as the SAM, which consists of the Shelf Management Controller (ShMC) and the Shelf
Management Mezzanine Module (ShMM) which installs on the carrier blade. Two SAMs are
installed into two dedicated shelf manager slots located at the bottom-rear of the AXP1440
shelf. The SAM is hot swappable and the connectors are accessible through the face plate.

The SAM supports redundant operation by automatic switchover between two SAMs. When
two SAMs are present in a shelf, one acts as the Active SAM and the other acts as a Standby
SAM. They share signals across the AdvancedTCA backplane that allow them to coordinate
their redundant operations. The SAM provides access to the IPMCs for the Power Entry Module
(PEM) and the two fan trays through the IPMB. The SAMs use IPM Sentry Shelf Manager
software for system management. Refer to
SAM Software on page 147 for further information.
The SAM also provides these operations for the AXP1440 shelf:

