7.7 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:

Screw activated faceplate switch

Presence signal indicating that the SAM is fully seated in its backplane connector

HS LED to indicate safe to remove state
7.8 Power
The SAM uses dual 48V power feeds, one from each PEM. Hot swap circuitry ensures correct
operation when a SAM is inserted into or removed from a live system.
