I have a Cisco 2650, NM-16a configured as a console server. There a 4 or 5 older SPARC machines being access via the serial port. A new server v20z was recently added. If I used the standard rollover (blue) cable from Cisco, I can access the server, but it I try to use the router, the console server. The connection try hangs as if it?s waiting for a signal. Has anyone use these new servers and what was done to make them work?
