FAQ
What does the 2AB0 suffix change in 6FC5210-0DF33-2AB0?
It identifies the PCU 50.3B-P order generation and must not be shortened to the earlier 2AA0 code.
Can the earlier PCU 50.3-P disk image be restored without checking the 50.3B hardware for 6FC5210-0DF33-2AB0?
No. Verify PCU base software, storage controller, drivers and license behavior for the B generation first.
Which interfaces should be inventoried before removing the PCU for 6FC5210-0DF33-2AB0?
Record Ethernet, MPI/DP, serial, USB and any legacy expansion or panel-display connection in actual use.
Why should the HMI project be kept separately from the system image for 6FC5210-0DF33-2AB0?
The project is the editable machine application; the image is the operating environment. Both are needed for a dependable recovery.
What should be tested immediately after the first boot for 6FC5210-0DF33-2AB0?
Check display output, HMI startup, control communication, network settings, peripherals and license state before production release.
Why is the PM760 description not enough to identify this spare for 6FC5210-0DF33-2AB0?
The PM760 performance class appears in more than one order generation. Use the full 6FC5210-0DF33-2AB0 MLFB.
