					download process. If not, or if the error persists after repeating the
					download process, replace the SNMP module.
OFF	OFF	OFF	ON	*	Port failure detected.

					router module and to the network. (Refer to “Connect the WAN
					Cable”, page 1-16, and to appendix A, “Cables and Connectors”.)
					2. If the error persists, make sure the WAN is specified correctly in
					the configuration. (Refer to “Create or Modify a Router
					Configuration”, page 2-5.)
					3. If the error still persists, check for a fault in the network equipment
					or links.
					4. If the error still persists, replace the WAN cable.
					5. If the error still persists, replace the router module.
