FMCS - DATABASE LOAD
Load After you put the diskette into the loader, the load process is automatic. Except to change diskettes, no further operation is necessary. - INCORRECT DISK INSERTED (the diskette does not compare with the diskette you used before).
CURRENT RECORD shows the number of data base records that are loaded into the FMC data base memory. TOTAL RECORDS show the total number of records to be loaded into the FMC data base memory.
During the loading process, the message LOAD IN PROGRESS shows. INSERT NEXT DISK shows during multi-disk data base load.
The load is complete when LOAD COMPLETE shows on the MCDU. Push the eject button on the loader to remove the diskette.
Load Failure Indications
If the loader finds a problem, a message shows on the data loader display and DATA LOAD INOP shows on the CDUs.
If the FMC finds a problem with the data from the loader, the MCDU shows one of these messages:
-CHECK DBL OR INTERFACE (there is a problem that the FMCS cannot isolate to the FMC or the loader) -DB EXCEEDS FMC (the data on the disk is too large for FMC memory) -RESET COUNT EXCEEDED (five load attempts have failed) -DB-OFP INCOMPATIBLE (the data on the disk does not compare with the FMC operational program) -CHECK MEDIA (part of the data on the disk cannot be read by the loader)

FMCS - CROSSLOAD PAGES
General
These are the two crossload pages that can show on the MCDU:
-OFP CROSSLOAD
-DATABASE CROSSLOAD.
NOTE: The OFP CROSSLOAD page will have priority over the DATA BASE CROSSLOAD page.
The OFP CROSSLOAD page shows for any of these conditions:
-If, during ground power up, the primary FMC finds a mismatch
between its valid OFP and that of the secondary FMC -An OFP with a different update version is loaded into one FMC -Selecting the CROSSLOAD prompt on the FMCS BITE INDEX
page if an OFP mismatch currently exists.
NOTE: If the OFP in the primary FMC is not valid, the MCDU shows a message to set the FMC source select switch to the BOTH ON R position.
If there is no mismatch between the OFPs but there is an analog discrete mismatch, the ANALOG DISCRETE page will show with the specific mismatch highlighted.
The DATABASE CROSSLOAD page will show if there are not any OFP or analog discrete mismatches for any of these conditions:
-If, during ground power up, there is a data base mismatch
between the primary and secondary FMCs.
737-700 MAINTENANCE TRAINING MANUAL
-A database with a different update version is loaded into one FMC. -Selecting the CROSSLOAD prompt on the FMCS BITE INDEX page if a data base mismatch currently exists.
The database pages show only the databases that do not match between FMCs. The data and header fields will be blank if there is no mismatch.
