Figure 3-6 Example of a ring topology with the MRP media redundancy protocol
The following rules apply to a ring topology with media redundancy using MRP:
● All the devices connected within the ring topology are members of the same redundancy
domain.
● One device in the ring is acting as redundancy manager.
● All other devices in the ring are redundancy clients.
Non MRP-compliant devices can be connected to the ring via a SCALANCE X switch or via
a PC with a CP 1616.

X-300 - modular devices (M)
Remember that in the modular switches the ring ports are located on MM900 media
modules.
