LED diagnostics: The diagnostics built into the server allow you to quickly identify the type of system error that occurred. When the System Error LED on the information LED panel is illuminated, use the following information to isolate the problem. An error message usually appears on the display monitor as well. If the System Error LED on the information LED panel on the front of the server is on, a system error was detected. Check the LEDs on the power supplies and at any Ethernet adapters, then open the cover and check to see which of the LEDs on the system board inside the server are on. (See "System board LEDs" on page 142 for the location of the LEDs.) System Board LED Service Processor Error LED on NMI LED on SMI LED on PCI 1 LED on PCI 2 LED on Description An error has occurred in the service processor. Actions: 1. Try a reset by turning off the system, jumper/short J39, and turn on the system. 2. Replace the system board. A non-maskable interrupt occurred. The PCI 1 or PCI 2 LED will probably also be on. Actions: 1. If the PCI 1 or PCI 2 LED is on, follow the instructions for those LEDs. 2. If the PCI 1 or PCI 2 LED is not on, restart the server. If the problem persists (the NMI LED stays on), go to "General Checkout" on page 5. A system-management interrupt occurred. This is an indication of service processor activity, and is not an error. Actions: No action is required. An error occurred on PCI bus 1. An adapter in PCI slot 5 or the system board caused the error. Actions: Check the error log for additional information. If the error log indicates a problem with the integrated Ethernet controller, replace the system board. An error occurred on PCI Bus 2. An adapter in PCI slot 1, 2, 3, or 4 or the system board caused the error. Actions: 1. Check the error log for additional information. 2. If you cannot correct the problem from the information in the error log, try to determine the failing adapter by removing one adapter at a time from the primary PCI bus 2 (PCI slots 1-4) and restarting the server after each adapter is removed.
