Light path diagnostics
To limit the need to slide the server out of the rack to diagnose problems, a light path
diagnostics panel is located at the front of the x366. This panel slides out from the front of the
server so the customer can view all light path diagnostics monitored server subsystems. In
the event that maintenance is required, the customer can slide the server out from the rack
and, using the LEDs, find the failed or failing component.
Light path diagnostics can monitor and report on the health of CPUs, main memory, hard disk
drives, PCI-X and PCI adapters, fans, power supplies, VRMs, and the internal system
temperature.
