Hi Iam reinstalling my RB450 through net-install but when i connect through putty using my serial cable there is continuous data flowing upwards and i cant select to boot from Ethernet.i pressed o then e but could just see the data flow upwards but when i reboot my router and use hyper terminal my terminal hangs cause of the data flow.i need help on how to stop the data flow so i can proceed further to select the options.Help would be Very much appreciated.

  • Make sure Ethernet cable and Netinstall server are connected to Ethernet1;
  • Disable hardware flow control and try Netinstall one more time;
  • Try another Null Modem cable;
  • Try another Terminal Emulation program for Netinstall.
