A connection between an HMC and either a service processor or BPC has been lost. The location code will identify the unit to which contact was lost.

1. If the ethernet switch is set to auto detect mode, go to step 2, otherwise set the ethernet switch to auto detect mode. This ends the procedure.
2. Is the system receiving power?
   • Yes: Continue with the next step.
   • No: Take the necessary action to restore power to the system. This ends the procedure.
3. Verify the system's connections to the HMC by choosing one of the following:
   • If you are working on a model 590 or 595, verify that the cables listed below are seated and functioning properly at both ends. See Locations — models 590 and 595 for diagrams and port location information, and Model 590 and 595 cables should you need to replace one of the cables.
     • BPC A (front) port J00A to the HMC.
     • BPC A (front) port J00B to service processor 2 (on the right) port J03.
     • BPC A (front) port J00C to service processor 1 (on the right) port J03.
     • BPC B (back) port J00A to the redundant HMC (if applicable).
       Note: BPC B must not be connected to the same HMC as BPC A.
     • BPC B (back) port J00B to service processor 2 (on the right) port J04.
     • BPC B (back) port J00C to service processor 1 (on the right) port J04.
   • If you are working on any other model, verify the network connection between the service processor and the HMC. See Finding part locations for diagrams and port location information.
   Does the problem persist?
   • Yes: Continue with the next step.
   • No: This ends the procedure.
4. Shut down the operating system for the server in preparation to reboot the server.
   Note: If the server is a 575, 590, or 595 you must first shut down the server and then remove the power by using the UEPO switch on the frame. Removing the power by using the UEPO switch (for these models) causes the BPC to also request a new IP address from the DHCP server when the server reboots.
   Reapply the power and boot the server. Does the problem persist?
   • Yes: Continue with the next step.
   • No: This ends the procedure.
5. Use SVCPROC to replace the service processor. If the problem persists, contact your next level of support.
   Note: If the server is a model 575, 590, or 595 contact your next level of support before replacing the service processor.
   This ends the procedure.
