PWR1907

A unit was dropped from the SPCN configuration.

1. Is the reference code you are working with 1xxx 913B?
   • No: Continue with the next step.
   • Yes: A system power control network (SPCN) microcode download is needed, but not started due to a policy setting. A manual download needs to be started:
   • Access the advanced system management interface (ASMI) and select "Configure I/O Enclosures"
   • Select the enclosure that the reference code has identified as needing the download
   • Select "Start enclosure microcode update". The SPCN microcode will now be loaded to the encloser.
   This ends the procedure.
2. Is the reference code you are working with 1xxx 90F0?

   No:

   Return to Start of call procedure.

   Yes:

   A unit was dropped from the SPCN configuration.

   This can be caused by any of the following:

   • The rack or unit has lost all ac or dc power.
   • The SPCN function in the unit has an error.
   • The SPCN/RIO frame-to-frame cables or the remote I/O (RIO) adapter card has failed.
3. Using the HMC or ASMI, find the 1xxx 90F0 in the error log (see Displaying error and event logs). Use the Show details option to display the location information for the failing unit.
4. After locating the failing unit, ensure that the RIO cables are seated correctly, reseat the RIO cables if necessary.

   Are the cables connected correctly?

   No:

   Correctly reconnect the RIO cables, or replace them if necessary. This ends the procedure.

   Yes:

   Continue with the next step.

5. Are the ac line cords on the failing unit connected properly at both ends?

   No:

   Reconnect the ac line cords, or replace them if necessary. This ends the procedure.

   Yes:

   Continue with the next step.

6. Check the voltage at the customer's ac outlet. Is the voltage correct?

   No:

   Inform the customer that the voltage at the ac power outlet is incorrect. This ends the procedure.

   Yes:

   Continue with the next step.

7. Are the power supplies functional?

   No:

   Perform the following:

   1. Refer to ../iphau_p5/locations.htm to determine the location and part number for each power supply, and to find the appropriate procedure for exchanging the power supplies.
   2. Replace each power supply one at a time, until the problem has been resolved.
   3. If the problem persists after replacing all of the power supplies, continue with the next step.

   Yes:

   Continue with the next step.

8. Replace the SPCN node in the failing unit. Go to symbolic FRU TWRCARD and perform the procedure. This ends the procedure.
