host interface to SDRR information, so software running on the server can
poll and retrieve the current status of the hardware. A shared register
interface is defined for this purpose.
SEL contents can be retrieved after system failure for analysis by field
service personnel using system management tools like Intel
®
LANDesk
®
Server Manager. Because the BMC is powered by 5V_Standby, SEL (and
SDRR) information is also available via the interperipheral management
bus (IPMB). An emergency management board like the Intel LANDesk
server management module (SMM) board can obtain the SEL and make it
remotely accessible using a LAN or telephone line connection.
During monitoring, the BMC performs the following functions:
•
System board temperature and voltage monitoring
•
Processor presence monitoring and fault resilient boot (FRB)
control
•
System board fan failure detection and indicator control
•
SEL interface management
•
SDRR interface management
•
SDR/SEL timestamp clock
•
System board field replaceable unit (FRU) information interface
•
System management watchdog timer
•
Periodic system management interrupt (SMI) timer
•
Front panel non-maskable interrupt (NMI) handling
•
Event receiver
•
ISA host and IPMB interface management
•
Secure mode control, front panel lock/unlock initiation, and video
blank and diskette write protect monitoring and control
•
Sensor event initialization agent
•
Wake-on-LAN via Magic Packet support
•
ACPI Support
•
Emergency Management Port (EMP) support
