This is essential to allow for linear or snet topologies of embedded switch devices. The examples and diagrams in this manual are included solely for illustrative purposes.

Outside United States Please contact your local Rockwell Automation representative for the return procedure. However, immediately after link-up the interface will send a few BPDUs to ensure a loop free topology.

Those wn either have an embedded switch or use an ETAP to connect to the topology. The chassis segmentation topology keeps the embedded switch topology completely isolated from the MSTP network. This creates an unblocked, bridge loop in the DLR ring. The remaining two ports on the embedded switch are connected to ports 1 and 2 on the module, which connect the module to the td0001 topology.

Because of this difference, and also because of the wide variety of uses for solid-state equipment, all persons responsible for applying this equipment must satisfy themselves that each intended application of this equipment is acceptable. Any timeouts or faults on the controllers are counted as a timeouts in the test results. This test verifies the detection of a failed supervisor.

Labels may be on or inside the equipment, for example, a drive or motor, to alert people that surfaces may reach dangerous temperatures. No additional switches are required. New Product Satisfaction Return Rockwell Automation tests all of its products to ensure that they are fully operational when shipped from the manufacturing facility.


Use the embedded switch technology in the following situations: This reduces the number of ports needed on the IES switch. Electronic Communications in Probability A Correction. In the case of DLR, the supervisor with the highest precedence value will become the active supervisor on the network.

This test validates that a backup supervisor can detect the loss of the ring supervisor and restore the blocked port.

There are three break points in this topology: If the ring closed before the supervisor is enabled, a bridge loop results, which generates a broadcast storm. Supervisor The DLR ring supervisor maintains a loop-free topology by blocking yd001 2 of the embedded-switch device.

If the l supervisor does not hear the supervisor for a period of time, it assumes the supervisor failed and takes over the supervisor role. Documentation Feedback Your comments will help us serve your documentation needs better. A new role, which was added in IOS version A topology change in the L always forces some of the traffic to be redirected down an alternate path. Trademarks not belonging to Rockwell Automation are property of their respective companies.

The default Beacon Timeout is based on a nominal device, embedded switch ring with m cables between devices.

These protocols can potentially cause other interruptions. A physical failure consists of unplugging the fiber cable from the port. There are two potential failure modes. Back-up supervisor nodes and ring nodes monitor the beacon frames to track ring transitions between Normal all links are working and Faulted the ring is broken in at least one place states.

The switch continues to classify and internally mark traffic based on the service policy. Linear topologies can be connected directly to the switch. In these cases, a bridge loop is created and causes a network failure.

In the MSTP topology, one of the gigabit Ethernet ports was the root port and the other was the alternate. If two ports configured ab-multiport-device are connected together a bridge loop will be formed.

To order paper copies of technical documentation, contact your local Allen-Bradley distributor or Rockwell Automation sales representative. A block on either of these ports is acceptable. Chapter Question Answer Chapter 1 What is a network?

The disadvantage of this topology is that it may require direct connection to the device-level topology for maintenance operations of non-CIP devices, such as diagnostics and configuration.

This test assesses DLR outages when the redundant switch topology experiences a disruption. The test alternates failing and then restoring the root tv001 on IES There are cases where the timeout may need to be increased to prevent unnecessary ring faults. Flex Links Redundant star Use the mixed topology when connecting to a network using Flex Links protocol.

Because these ports are connected to a single NIC, they cannot be used to connect to multiple Ethernet networks.

It lets you combine both single-port devices and devices with embedded switch technology. You can contact Customer Support for initial help in getting your product up and running. We do not recommend connecting device-level topologies directly to Layer 3 distribution switches. Do not connect two ports configured with the ab-multiport-device together, either directly or indirectly. Allen-Bradley devices with embedded switch technology have these features in common: Switch Redundant Star Timeout.
