The solution in both cases is to ensure that the cable is firmly connected at both ends. If the problem

continues, replace the cable. It is possible that there could be a problem with the stack port itself.

In this case, validation of this issue requires the installation of a known good cable to see if that

cable also fails.

The port state is not UP until both ends of the cable are connected and the cable has been validated

as a genuine HP cable.
