Safety Instructions Regarding your Product

Before you use the product described here, read the safety instructions below thor-

oughly.

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.

Notice

If a device is replaced, remember the following points relating to a SCALANCE X-400

switch:

● Make the same settings on the DIL switches as they were on the old device.

● Make sure that you use a media module and extender configuration that is iden-

tical to that of the old device.

● Use the C-PLUG of the old device in the new one so that your device configura-

tion is adopted.
