*3 If you have replaced the CPU memory unit lower and the XCP firmware version is different between the maintenance part and the existing system, the message "XSCF firmware update now in progress. BB#xx, please wait for XSCF firmware update complete." appears at login to the XSCF. Then, the XCP firmware version will be automatically matched. The version matching takes about 50 minutes. Execute the showlogs monitor command, and check for the "XCP firmware version synchronization completed" message. The displayed message indicates the completion of XCP firmware matching.
*4 If you have replaced the CPU memory unit lower using the replacement microSD card in "7. Replacing a faulty FRU," the "SCF:Gaps between BB-ID" message may appear in the error log. If so, ignore the message.
*5 If you have replaced the CPU memory unit lower in "7. Replacing a faulty FRU," the "SCF:SCF Diagnosis initialize RTC" message may appear in the error log. If so, ignore the message.
*6 In replacement of a FRU other than the CPU memory unit lower in "7. Replacing a faulty FRU," this work is not required. Even if you switched the microSD card when replacing the CPU memory unit lower, this work is not required.
