Please tell me the exact model number of node that you have. Depending on what you have and what version components you have, there may be a need for other parts or upgraded components. There was a specific version of NOR that was not compadabile with redunancy use with the NFS.
Please feel free to e-mail or call. I used to be an FE with Philips Broadband Networks and might be able to give you some help.
