ThinkSystem System Manager event log
The ThinkSystem System Manager monitors the physical state of the server and its components using
sensors that measure internal physical variables such as temperature, power-supply voltages, fan speeds,
and component status. The ThinkSystem System Manager provides various interfaces to system
management software and to system administrators and users to enable remote management and control of
a server.

Light path diagnostics
Light path diagnostics is a system of LEDs on various external and internal components of the server that
leads you to the failed component. When an error occurs, LEDs are lit on the front I/O assembly, the rear
panel, the system board, and the failed component. By viewing the following LEDs, you can often identify the
system and device status and diagnose problems.
• “Operator information panel” on page 15
• “Rear view LEDs” on page 20
• “System board LEDs” on page 24
