Multiple nodes - loss of connectivity to the data network
Use the information in this section to troubleshoot intermittent multiple-node connectivity loss in the chassis.
Complete the following steps until the problem is solved:
- Test the I/O module that the devices are connected to by using the diagnostic tools that are provided by the manufacturer.
- Attempt to connect one node to the network first, and then try to bring the others online to isolate the problem.
- Check the I/O module firmware and update it if necessary.ImportantRebooting and running POST diagnostics on the I/O module might also help to isolate the problem; however, this will temporarily disable the data network.
