Siemens SCALANCE X-200 Configuration Manual page 73

● MRP Client
Here, you can select the "MRP Client" role.
In an MRP ring, at least one device must be set either to the "Automatic Redundancy
Detection" role or to the "MRP Manager (Auto)/Client" role. You also have the option of
setting the "MRP Client" role for all other devices. If all except one device in the ring is
configured as "MRP Client", this device automatically adopts the role of MRP manager.
Select the "MRP Client" role if you want to operate the device along with components that
do not originate from Siemens in the ring.
● MRP Manager (Auto)/Client
Devices with the setting "Automatic Redundancy Detection" or "MRP Manager
(Auto)Client" negotiate among themselves which device will adopt the MRP manager
role. The device with the lowest MAC address will always become the MRP manager. In
contrast to the setting "Automatic Redundancy Detection", the devices cannot detect
whether or not an HRP manager is in the ring. This means that they never adopt the role
of "HRP Client".
● HRP Client
Here, you can select the role "HRP Client".
Select the role "HRP Client" if you want to use the standby functionality of the X-200 IE
switch.
● HRP Manager
Here, you can select the role HRP Manager. When you configure an HRP ring, exactly
one module must be set as HRP manager. All other devices must be configured as HRP
clients.
Note
Ring ports after resetting to factory settings
If you reset to factory defaults, the redundancy role Automatic Redundancy Detection (ARD)
becomes active. The configuration of the ring ports is also reset to the ports set in the
factory.
You will find the default ring ports of the individual X-200 variants in the Appendix Default
ring ports (Page 177).
If other ports were used previously as ring ports, with the appropriate attachment, a
previously correctly configured device can cause circulating frames and therefore the failure
of the data traffic.
First ring port
Relevant only when the Automatic Redundancy Detection role, MRP client or HRP client is
selected and the HRP manager or MRP manager role was adopted.
Here, you select which is the first ring port.
Second ring port
Relevant only when the Automatic Redundancy Detection role, MRP client or HRP client is
selected and the HRP manager or MRP manager role was adopted.
Here, you select which is the second ring port.
