The CPU is on strike
Thread Content
The replacement main control card has stopped working; the system is still running. How should this be handled?
The main control card of the DCS system? If everyone is on strike, how is it still running? CPU redundant?
Should the main control cards all support hot swapping? Does “strike” mean not operating? Why is it still running?
The controllers are configured in a one-in-one-backup setup, with hot-swapping support. If it is confirmed that the CPU damage is not caused by issues such as the base or power supply, simply replace it. Once replaced, both controllers will synchronize automatically, and no further installation is required ； If the damage is caused by the base or the chassis, that’s a big problem. . .
There is no synchronization; after switching to the shutdown mode, the operation fails, and it automatically returns to operating with the original control card. Server B is unable to download data
