This Fault LED is powered by 3.3V standby power. DIMM and CPU fault LEDs on the CPU module provide further indications of which component has a fault condition. These CPU and DIMM fault LEDs can be lit for up to one minute by a capacitor on the CPU module, even after the CPU module is removed from the server. To light the fault LEDs from the capacitor, push the small button on the CPU board labeled, "Press to see fault." See FIGURE 3-23 for the LED and button locations. ■ System Controller fault LED: Off: CPU and DIMMs are functioning properly. On (amber): CPU or DIMM is faulty. DIMM fault LEDs are under the DIMM ejector levers that are toward the front of the system: ■ DIMM fault LED: 3-50 Sun Fire X4500/X4540 Server Service Manual • May 2010
