Bảng đèn của Server IBM 3650

Nội dung bên dưới cho biết ý nghĩa của các đèn báo trong bảng đèn của server. Và các việc cần kiểm tra trên server.
Table 1. Light path diagnostics panel LEDs
  • Follow the suggested actions in the order in which they are listed in the Action column until the problem is solved.
  • If an action step is preceded by “(trained technician only),” that step must be performed only by a trained technician.
LED Description Action
Check log LED An error has occurred and cannot be isolated without performing certain procedures.
  1. Check the IMM2 system event log and the system-error log for information about the error.
  2. Save the log if necessary and clear the log afterwards.
System-error LED An error has occurred.
  1. Check the light path diagnostics LEDs and follow the instructions.
  2. Check the IMM2 system event log and the system-error log for information about the error.
  3. Save the log if necessary and clear the log afterwards.
PS When only the PS LED is lit, a power supply has failed.
The system might detect a power supply error. Complete the following steps to correct the problem:

  1. Check the power-supply with a lit yellow LED (see Power-supply LEDs).
  2. Make sure that the power supplies are seated correctly and plugged in a good AC outlet.
  3. Remove one of the power supplies to isolate the failed power supply.
  4. Make sure that both power supplies installed in the server are of the same AC input voltage.
  5. Replace the failed power supply.
PS + CONFIG
When both the PS and CONFIG LEDs are lit, the power supply configuration is invalid.
If the PS LED and the CONFIG LED are lit, the system issues an invalid power configuration error. Make sure that both power supplies installed in the server are of the same rating or wattage.
OVER SPEC The system consumption reaches the power supply over-current protection point or the power supplies are damaged.
  1. If the Pwr Rail (A, B, C, D, E, F, G, and H) error was not detected, complete the following steps:
    1. Use the Power Configurator utility to determine current system power consumption. For more information and to download the utility, go to the IBM Power Configurator website.
    2. Replace the failed power supply.
  2. If the Pwr Rail (A, B, C, D, E, F, G, and H) error was also detected, follow actions listed in Power problems and Solving power problems.
PCI An error has occurred on a PCI card, a PCI bus, or on the system board. An additional LED is lit next to a failing PCI slot.
  1. Check the riser-card LEDs, the ServeRAID error LED, and the dual-port network adapter error LED to identify the component that caused the error.
  2. Check the system-error log for information about the error.
  3. If you cannot isolate the failing component by using the LEDs and the information in the system-error log, remove one component at a time; and restart the server after each component is removed.
  4. Replace the following components, in the order shown, restarting the server each time:
    • PCI riser cards
    • ServeRAID adapter
    • Optional network adapter
    • (Trained technician only) System board
  5. If the failure remains, go to the “Before you call IBM Service” website.
NMI A nonmaskable interrupt has occurred, or the NMI button was pressed.
  1. Check the system-error log for information about the error.
  2. Restart the server.
CONFIG CONFIG + PS
An invalid power configuration error has occurred.
If the CONFIG LED and the PS LED are lit, the system issues an invalid power configuration error. Make sure that both power supplies installed in the server are of the same rating or wattage.
CONFIG + CPU
A hardware configuration error has occurred.
If the CONFIG LED and the CPU LED are lit, complete the following steps to correct the problem:

  1. Check the microprocessors that were just installed to make sure that they are compatible with each other (see Replacing a microprocessor and heat sink for additional information about microprocessor requirements).
  2. (Trained technician only) Replace the incompatible microprocessor.
  3. Check the system-error logs for information about the error. Replace any component that is identified in the error log.
CONFIG + MEM
A hardware configuration error has occurred.
If the CONFIG LED and the MEM LED are lit, check the system-event log in the Setup utility or IMM2 error messages. Follow steps indicated in UEFI/POST diagnostic codes and Integrated management module II (IMM2) error messages.
LINK Reserved.
CPU When only the CPU LED is lit, a microprocessor has failed.
If the CONFIG LED is not lit, a microprocessor failure occurs, complete the following steps:

  1. (Trained technician only) Make sure that the failing microprocessor and its heat sink, which are indicated by a lit LED on the system board, are installed correctly. See Replacing a microprocessor and heat sink for information about installation and requirements.
  2. (Trained technician only) Replace the failing microprocessor (seeRemoving a microprocessor and heat sink and Replacing a microprocessor and heat sink).
  3. For more information, go to the “Before you call IBM Service” website.
CPU + CONFIG
When both the CPU LED and the CONFIG LED are lit, the microprocessor configuration is invalid.
If the CONFIG LED and the CPU LED are lit, the system issues an invalid microprocessor configuration error. Complete the following steps to correct the problem:

  1. Check the microprocessors that were just installed to make sure that they are compatible with each other (see Replacing a microprocessor and heat sink for additional information about microprocessor requirements).
  2. (Trained technician only) Replace the incompatible microprocessor.
  3. Check the system-error logs for information about the error. Replace any component that is identified in the error log.
MEM When only the MEM LED is lit, a memory error has occurred.
Note: Each time you install or remove a DIMM, you must disconnect the server from the power source; then, wait 10 seconds before restarting the server.
If the CONFIG LED is not lit, the system might detect a memory error. Complete the following steps to correct the problem:

  1. Update the server firmware to the latest level (see Updating the firmware).
  2. Reseat or swap the DIMMs with lit LED.
  3. Check the system-event log in the Setup utility or IMM error messages. Follow steps indicated in UEFI/POST diagnostic codesand Integrated management module II (IMM2) error messages.
  4. Replace the failing DIMM (see Removing a memory module andInstalling a memory module).
MEM + CONFIG
When both the MEM and CONFIG LEDs are lit, the memory configuration is invalid.
If the MEM LED and the CONFIG LED are lit, check the system-event log in the Setup utility or IMM2 error messages. Follow steps indicated in UEFI/POST diagnostic codes and Integrated management module II (IMM2) error messages.
TEMP The system or the system component temperature has exceeded a threshold level. A failing fan can cause the TEMP LED to be lit.
  1. Make sure that the heat sink is seated correctly.
  2. Determine whether a fan has failed. If it has, replace it.
  3. Make sure that the room temperature is not too high.
  4. Make sure that the air vents are not blocked.
  5. Make sure that the heat sink or the fan on the adapter, or the optional network adapter is seated correctly. If the fan has failed, replace it.
FAN A fan has failed, is operating too slowly, or has been removed. The TEMP LED might also be lit.
  1. Check if your server installed with the adapters mentioned inTable 1. If yes, make sure your server compile with the configuration with four fans installed.
  2. Reseat the failing fan, which is indicated by a lit LED near the fan connector on the system board.
  3. Replace the failing fan
BOARD An error has occurred on the system board or the system battery.
  1. Check the LEDs on the system board to identify the component that caused the error. The BOARD LED can be lit due to any of the following reasons:
    • Battery
    • (Trained technician only) System board
  2. Check the system-error log for information about the error.
  3. Replace the failing component:
    • Battery
    • (Trained technician only) System board
HDD A hard disk drive has failed or is missing.
  1. Check the LEDs on the hard disk drives for the drive with a lit status LED and reseat the hard disk drive.
  2. Reseat the hard disk drive backplane.
  3. If the error remains, replace the following components one at a time, in the order listed, restarting the server after each:
    1. Replace the hard disk drive.
    2. Replace the hard disk drive backplane.
