Chassis Subsystem
Revision 1.1 Intel order number G90620-002 97
10. Chassis Subsystem
The BMC monitors several aspects of the chassis. Next to logging when the power and reset buttons get pressed, the BMC also
monitors chassis intrusion if a chassis intrusion switch is included in the chassis, as well as looking at the network connections, and
logging an event whenever the physical network link is lost.
10.1 Physical Security
Two sensors are included in the physical security subsystem: chassis intrusion and LAN leash lost.
10.1.1 Chassis Intrusion
Chassis Intrusion is monitored on supported chassis, and the BMC logs corresponding events when the chassis lid is opened and
closed.
10.1.2 LAN Leash Lost
The LAN Leash lost sensor monitors the physical connection on the on-board network ports. If a LAN Leash lost event is logged, this
means the network port lost its physical connection.
