Information LED: When this LED is lit, it indicates that a noncritical event has occurred. System-error LED: When this LED is lit, it indicates that a system error has occurred. An LED on the light path diagnostics panel on the side of the operator information panel is also lit to help isolate the error. For details, see the section about the light path diagnostics panel and internal LED locations in the Option Installation Guide on the IBM xSeries Documentation CD. USB connector: You can connect a USB device to this connector. Release latch: Press this latch to release the operator information panel to access the light path diagnostics LED panel. Light path diagnostics LED panel Swing the operator information panel out to see the light path LED panel on the side of the operator information panel. The following illustration shows the LEDs on the light path LED panel. PS1 TEMP VRM PCI DASD NMI EXP OVER SPEC PS2 FAN CPU MEM NR SP LOG REMIND PS1 LED: When this LED is lit, it indicates that power supply 1 has failed. PS2 LED: When this LED is lit, it indicates that power supply 2 has failed. TEMP LED: When this LED is lit, it indicates that the system temperature has exceeded a threshold level. FAN LED: When this LED is lit, it indicates that a hot-swap fan or power-supply fan has failed or is operating too slowly. A failing fan can also cause the OVER TEMP LED to be lit. VRM LED: When this LED is lit, it indicates that a VRM on the microprocessor tray has failed. CPU LED: When this LED is lit, it indicates that a microprocessor has failed. PCI LED: When this LED is lit, it indicates that an error has occurred on a PCI bus. MEM LED: When this LED is lit, it indicates that a memory error has occurred. DASD LED: When this LED is lit, it indicates that a hot-swap hard disk drive has failed. NR LED: When this LED is lit, it indicates that two power supplies are present but the power supplies are not redundant. NMI LED: When this LED is lit, it indicates that there has been a nonmaskable interrupt (NMI). SP LED: When this LED is lit, it indicates that the service processor has encountered an error. 34 xSeries 365 Type 8861 and 8862: Installation Guide
