(ip, mask, etc) Do you have SELinux enabled? If yes, disable it and test again. Have you turned off your firewall. Same deal as SEL. Have you tried "service network start/restart" Have you set your speed/duplex to match that of the port on the switch? Can you ping 127.0.0.1? These are all the first things I look at when faced with network issues. HTH.
