Chapter 5: System Monitoring and Alarms

MMC Functions
The MMC performs system monitoring and alarming functions using the flexible, industry
standard, Intelligent Platform Management Interface (IPMI). The module comes equipped with
an on-board MMC and IPMI v1.5 firmware already installed on the module. The MMC firmware
is based on Pigeon Point System
®
's (PPS) MMC firmware. Some of the functions available on
the module through the IPMI interface include:
•
Monitoring of the CPU and board temperatures with critical and non-critical alerting
•
Monitoring of the voltage rails with critical and non-critical alerting
•
Remote reset and shutdown of the module (hard and soft)
•
Monitoring of ejector switches for hot-swap functionality (Performance Technologies’ NexusWare
IPMI driver and firmware provide additional payload features for hot swap)
•
Monitoring and event reporting of critical errors
•
Fabric and clock e-keying
•
Interface to local IPMB (IPMB-L)
In order to take advantage of the features provided by the firmware, IPMI-aware applications
must be developed. Information on IPMI v1.5 is provided at:
http://www.intel.com/design/servers/ipmi/spec.htm
Summary of Supported Commands
Table 5-1, “IPMI/PICMG Command Subset Supported by the MMC Firmware,”
lists all the
commands supported by the MMC.
The
Spec Ref
column indicates where in the relevant specification a command is defined. IPMI
references are to v1.5 unless indicated otherwise. The
MMC Req
column indicates if a
particular command is required by the relevant specification (
AMC Specification
or
