 Cisco C6500 password recovery

C6500的password recovery基本上與一般router的password recovery一致，重點在於必須在啟動後約25-60秒，等C6500將console的所有權交給RP(Route Processor)，再輸入Fn + Break進行中斷。

務必在出現下列畫面之後，才可以進行中斷，否則一樣會載入config，致使前功盡棄。===============================================================================================
