NeXtScale nx360 M4 34
To aid with problem determination, the server includes light path diagnostics, which is a set of LEDs on
the front of the server and inside the server that show you which component is failing. The LEDs are
shown in the following figure.
Figure 11. Power button and system LEDs
When an error occurs, the system error LED lights up. Review the logs through the web interface of the
IMMv2 (see the "Remote server management" section). 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.
Remote server management
The server contains 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 FoD licenses; however, you might need to upgrade
the system firmware to the latest levels (at least level 28n) to support these upgrades.
