The TMM combines service processor functions, video controller, and remote presence and blue-screen
capture features in a single chip. The TMM provides advanced service-processor control, monitoring,
and alerting function. If an environmental condition exceeds a threshold or if a system component fails,
the TMM lights LEDs to help you diagnose the problem, records the error in the TMM event log, and
alerts you to the problem. Optionally, the TMM also provides a virtual presence capability for remote
server management capabilities. The TMM provides remote server management through the following
industry-standard interfaces:
– Intelligent Platform Management Protocol (IPMI) version 2.0
– Simple Network Management Protocol (SNMP) version 3
– Common Information Model (CIM)
– Web browser
For more information about the TMM, see “Using the TMM” on page 38, “TMM error messages” on
page 152.
