8.7 Hot Swap Interface
The SAM provides a hot swap interface allowing the SAM to be replaced without powering
down the shelf. The hot swap interface is implemented using the shelf manager mezzanine
CPLD device. The interface is composed of three components:
z Injector/Ejector handle switch
z Presence signal indicating that the SAM is fully seated in its backplane connector
z HS LED to indicate safe to remove state
8.8 Power
The SAM uses dual +12V power feeds, one from each PEM. Hot swap circuitry ensures correct
operation when a SAM is inserted into or removed from a live system.
8.9 SAM Software
The software that runs on the shelf manager is described in detail in the Pigeon Point Systems
IPM Sentry Shelf Manager User Guide, which provides an introduction to shelf management, the
shelf manager, and the shelf management mezzanine. Also available is the Pigeon Point Systems
IPM Sentry Shelf-External Interface Reference which describes the command line, web, SNMP
(Simple Network Management Protocol), and RMCP (Remote Management Control Protocol)
interfaces. Refer to Appendix A, Related Documentation for more information on these
publications.
