The fault-tolerant system is operating in redundant system mode.
To edit the CPU parameters of a fault-tolerant system, follow the steps outlined below.
Details of each step are described in a subsection.
1 Editing CPU parameters offline Step 1: Editing CPU parameters offline
2 Stopping the reserve CPU Step 2: Stopping the reserve CPU (Page 176)
3 Downloading modified CPU parameters to the reserve
Step 3: Downloading a new hardware configura-
tion to the reserve CPU (Page 177)
4 Switch to CPU with modified configuration Step 4: Switching to CPU with modified configura-
5 Transition to redundant system mode Step 5: Transition to redundant system mode
Note
After changing the hardware configuration
, download takes place practically automatically.
You then no longer have to perform the steps described in sections
Step 2: Stopping the
(Page 176) to Step 5: Transition to redundant system mode (Page 179). The
system behavior remains as described.
