Troubleshoot and General
Solutions for Linear or DLR
Networks Before you attempt to correct specific faults on your linear or DLR network, we
recommend that you first take the following actions when a fault appears.
• For a DLR network:
– verify that you have configured at least one node as a supervisor on the
network and that Network Topology = Ring.
– verify that all cables on the network are securely connected to each
device.
– verify that all devices that require an IP address have one assigned
correctly.
– check the Network Status field on the active supervisor node’s status
page to determine the fault type.
• For a linear network:
– verify that none of the nodes are configured as a supervisor on
the network and that Network Topology = Linear.
– If any nodes on a linear network are configured as a supervisor,
it may
impact communication to other devices connected to the network.
– verify that all cables on the network are securely connected to each
device.
– verify that all devices that require an IP address have one assigned
correctly.
If the fault is not cleared once you have completed the actions listed above, use
the tables in the rest of this chapter to troubleshoot issues specific to a DLR
network or a linear network.
