Remote management
The server contains IBM Integrated Management Module II (IMM2), which provides advanced
service-processor control, monitoring, and an alerting function. If an environmental condition exceeds a
threshold or if a system component fails, the IMM2 lights LEDs to help you diagnose the problem, records
the error in the event log, and alerts you to the problem. The server includes IMM2 Basic and can be
upgraded to IMM2 Standard and IMM2 Advanced with Feature on Demand (FoD) licenses, however, you
may need to upgrade system firmware to the latest levels (at least level 28n) to support these upgrades.
IMM2 Basic has the following features:
Industry-standard interfaces and protocols
Intelligent Platform Management Interface (IPMI) Version 2.0
Common Information Model (CIM)
Advanced Predictive Failure Analysis (PFA) support
Continuous health monitoring
Choice of a dedicated or shared Ethernet connection
Domain Name System (DNS) server support
Dynamic Host Configuration Protocol (DHCP) support
