Firmware Checkpoints

The following Fxx code checkpoints are displayed on the operator panel during system startup, and can be used for diagnostic purposes.

If you replace FRUs and the problem is still not corrected, go to MAP 0030 in the Diagnostics Information for Multiple BusunlessSy temsotherwise indicated in the

tables.
