A power supply might be the failing item.

For more information about failing part numbers, location codes, or removal and replacement procedures, see Part locations and location codes. Select your machine type and model number to see applicable procedures for your system.

Attention: In a system with redundant power supplies, verify that the green ac input LED or dc input LED, and the green dc output LED on the power supply that is not being replaced is on solid for 30 seconds before you replace the failing power supply.
Attention: When you replace a redundant power supply, a 1xxx15x0 or 1xxx15x4 reference code might surface in the error log. If you removed and replaced the power supply in the location that is associated with this reference code, and the power supply became ready (ac input LED or dc input LED is on solid, and the dc output LED is on solid or flashing) after installation, disregard this reference code. If you did not previously remove and replace a power supply, the power supply did not become ready after installation, or there are repeated fan fault errors after the power supply replacement, continue to follow this procedure.
Note: The following table provides information about power supply LEDs.
LED Description
The ac input LED or dc input LED This LED is green and is on (lit) if the ac or dc input voltage is present and off (not lit) if the ac or dc input voltage is not present. For normal system operation, this LED is on solid.
The dc output LED This LED is green and is on solid if the power supply output voltages are correct. If the power supply control voltage is present and the power supply outputs are not powered on, the power supply is in standby and the dc output LED flashes at a rate of 1-3 times per second. The dc output LED is off if both the power supply control voltage and the output voltages are bad. For normal system operation, this LED is on solid.
The identify LED The identify LED is amber and will be turned on and off at a 4 second rate, 10 seconds after the application of input power to the supply, if serial communication isn't established with the service processor. For normal system operation, this LED is off.
  1. Is the reference code 1xxx15xx or 1xxx71xx?
    • No: Continue with the next step.
    • Yes: Complete the following steps:
      1. Find the unit reference code in the following table to determine the FRU part number and location for the failing power supply.
      2. Ensure that the power cables to the power supply are properly connected and seated. If an additional power supply was recently plugged in, verify that the dc output LED is on for 30 seconds before you unplug this power supply. The green dc output LED on the power supply is turned on when power is correctly connected to the power supply.
      3. Verify that the ac input LEDs or dc input LEDs on all of the power supplies within the enclosure are turned on.
        • If the LED is off on any of the power supplies, ensure that the power cable is properly connected to the power supply.
        • If you have a 9080-MHE, 9080-MME, 9119-MHE, or 9119-MME system or an EMX0 PCIe3 expansion drawer and if a power supply has an ac input LED or dc input LED turned off, ensure that the cable that connects the line cord conduit (9080-MHE, 9080-MME, 9119-MHE, or 9119-MME) or the power supply conduit (EMX0 PCIe3 expansion drawer) to the power supply is properly seated. If the problem persists, replace the line cord conduit or the power supply conduit.
        Does the problem persist?
        • Yes: Continue with step 1.d.
        • No: This ends the procedure.
      4. Is the reference code 1xxx15x0?
        • Yes: Before you replace any parts, complete isolation procedure PWR1911.
        • No: Continue with step 1.e.
      5. Replace the failing power supply (see the following table to determine which power supply to replace and its location).
      6. Complete the following steps if the new power supply does not fix the problem:
        1. Reinstall the original power supply.
        2. Try the new power supply in each of the other positions that are listed in the table.
        3. If the problem still is not fixed, reinstall the original power supply and go to the next FRU in the list.
        4. For reference codes 1xxx15x0, replace the system backplane if a problem persists after you replace the power supply. If that does not resolve the problem, contact your next level of support.
      7. Use the following table to determine the part number for the field replaceable unit (FRU).
