Notice
When using a SCALANCE X-400 in the ring (HSR, High Speed Redundancy), check
the RM DIL switch before closing the ring cable. If the SCALANCE X-400 adopts the
function of a redundancy manager, the switch must be set to ON. If the SCALANCE
X-400 is not being used as a redundancy manager, the switch must be set to OFF.

Notice
When using a SCALANCE X-400 in redundancy manager mode (RM = ON), check
whether the DIL switches R1 and R2 select the required ring ports before closing the
ring. If ports other than those set are connected to the ring, they cause a ring short-
circuit and overload the network.

Notice
When supplied, the DIL switches R1 and R2 are set to OFF. This means that the gi-
gabit ports on slot 5 are defined as ring ports and ring redundancy is activated. In this
case, you cannot activate rapid spanning tree / spanning tree.
