Light path diagnostics LEDs
Use this information to diagnose possible errors that are indicated by the light path diagnostics LEDs.
The following table describes the LEDs on the light path diagnostics panel and the light path diagnostics
LEDs on the system board. See “Viewing the light path diagnostics LEDs” on page 61 for information
about lighting the LEDs.
Lit light path diagnostics LED
Description
None
The compute node is not sufficiently charged to display the LEDs on the system
board.
BMC error
Future use only.
Battery error
The system CMOS battery is not installed or is not working.
DC power error
Future use only.
DIMM
x
error
A memory error occurred.
I/O expansion unit
Future use only.
Light path diagnostics
The power source for the light path diagnostics LEDs is charged.
Light path diagnostics only
No errors have occurred.
Memory
A memory error has occurred.
Microprocessor
x
error
The IMM2 lights this LED when a microprocessor has failed or overheated or the
start microprocessor (CPU 1) is missing. The fault LED on the front panel is also lit.
Mismatch
The microprocessors are mismatched. If the MEM LED is also lit, the DIMMs
are mismatched.
NMI
The system board has failed.
System board
The system board has failed.
Temperature
The system temperature has exceeded a threshold level.
LSI SAS Error
A SAS error has occurred.
IMM event log
Use this information as an overview of the IMM event log.
The Integrated Management Module II (IMM2) consolidates the system-management processor functionality,
video controller, and remote presence capabilities in a single chip on the system board. The IMM2 monitors
all components of the compute node and posts events in the IMM event log. In addition, most events are
also sent to the Chassis Management Module event log. You can view the IMM event log through the
Dynamic System Analysis (DSA) program (as the ASM event log).
