Back up the data of a specific SMI (p4690, p4691)
1. Find out the component number of the SMI
If you want to back up the data of a specific SMI, you must find out its component number.
You can read this number in the target topology overview.
Figure 12-21 Finding the component number of an SMI in the target topology
2. Back up the SMI data (p4690, p4691)
The component number of the SMI which needs data backup is entered in CU parameter
"SMI component number" p4690. This is 3 in the example.
The process is started with p4691=1.
When all the data have been backed up, parameter p4691 is reset to 0 automatically.
If data backup has not been successful, the parameter is not reset to zero, but to a fault
value instead.
The backup fault values are as follows:
13: Insufficient space on the memory card
14: Format of backup data is incorrect
Remedy:
With fault value = 13:
Use a higher-capacity memory card.
With fault value = 14:
There are two different hardware versions of SMI devices, i.e. they differ in terms of
processor system. The old hardware version (SAC) supports the data format "block
structure" while the new version (DAC) supports the data formats "block structure" and
"EFS". If data have been backed up from the old hardware version, they can be transferred
to a module with the new hardware version. However, data from new hardware versions
cannot be transferred to old hardware versions.
