management” on page 105). If needed, power off the server and remove it
from the enclosure. Then, press and hold the power button to activate the
system board LEDs. The LED next to the failed component lights up.
Below the LEDs is a QR code (2D bar code) that, when scanned, contains the
machine type and model number (MTM), followed by the serial number of the
server.
4.15 Remote server management
Each IBM NeXtScale nx360 M4 compute node has an Integrated Management
Module II (IMM2) onboard and uses the Unified Extensible Firmware Interface
(UEFI) to replace the older interface.
IMM2 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 might need to
upgrade the system firmware to the latest levels 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
Shared Ethernet connection
Domain Name System (DNS) server support
Dynamic Host Configuration Protocol (DHCP) support
Embedded Dynamic System Analysis (DSA)
LAN over USB for in-band communications to the IMM
Serial over LAN
Server console serial redirection
Remote power control
