Only a controller module within S12F-R1432, the dual-controller
subsystem, can be replaced online while the subsystem is
servicing I/Os.
When replacing the controller module, always remember that the
controller board is one of the most sensitive
subsystem. All previously stipulated safety precautions (see
Section 2.3
) must be strictly adhered to. Failure to adhere to
these precautions can result in permanent damage to the
controller board, resulting in lengthy delays.
When S12F-R1432 operates in the dual-active mode and one (1)
controller fails, a transparent

subsystem. Once the failed controller is replaced, a transparent
failback will ensure that the I/O workload is once again distributed
between the two controllers.
