7.4.2 System-Stopped/Cold Maintenance


7.4.2 System-Stopped/Cold Maintenance
All the FRUs can be replaced in the maintenance in the system-stopped/cold state and with all the crossbar boxes and the SPARC M12-2S/M10-4S powered off.
Figure 7-15 shows FRUs with system-stopped/cold maintenance enabled.
Figure 7-15  FRUs With System-Stopped/Cold Maintenance Enabled
Figure 7-15 FRUs With System-Stopped/Cold Maintenance Enabled
Note - When replacing the microSD card at the same time as the XSCF unit of a SPARC M10 system, replace them during system-stopped/hot maintenance.
Note - The XSCF unit and the interface unit cannot be replaced at the same time. If you replace them at the same time, the system may not start correctly. When replacing both the XSCF unit and the XSCF interface unit, replace only one of them first. After its firmware startup completes, disconnect the power cord of the other unit for replacement.
Note - To remove the XSCF BB control cable, the XSCF DUAL control cable, and the crossbar cable from the chassis and reconnect them, see "Appendix B Cable Connection Information on Building Block Configurations" in the Fujitsu SPARC M12-2S Installation Guide or "Appendix B Cable Connection Information on Building Block Configurations" in the Fujitsu M10-4S/SPARC M10-4S Installation Guide.
For the workflow and procedure for replacing FRUs in the system-stopped/cold state, see Figure 7-16 and Table 7-12.

*1 If you have replaced an XSCF unit 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 version matching in an XCP firmware update.
*2 If you have replaced the XSCF unit using the replacement microSD card in "6. Replacing a faulty FRU," the "SCF:Gaps between XBBOX-ID" message may appear in the error log. If so, ignore the message.
*3 If you have replaced an XSCF unit in "6. Replacing a faulty FRU," the "SCF:SCF Diagnosis initialize RTC" message may appear in the error log. If so, ignore the message.
*4 In replacement of a FRU other than an XSCF unit in "6. Replacing a faulty FRU," this work is not required. Even if you switched the microSD card when replacing an XSCF unit, this work is not required.
