Use the information in this section to troubleshoot intermittent
multiple-node connectivity loss in the chassis.
Action
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.
Important: Rebooting and running POST diagnostics on the I/O
module might also help to isolate the problem; however, this will
temporarily disable the data network.
