各位前輩好,

小弟有一台C9300,在重新恢復原廠設定之後,重開機進不了 Switch> 模式,詳細資訊如下 :

請問大家,小弟該如何做,才能重新 進去 Switch> 模式呢 ?

Switch#factory-reset all
The factory reset operation is irreversible for all operations. Are you sure? [confirm]y
The following will be deleted as a part of factory reset:
1: Crash info and logs
2: User data, startup and running configuration
3: All IOS images, including the current boot image
4: OBFL logs
5: User added rommon variables
6: Data on Field Replaceable Units(USB/SSD/SATA)
The system will reload to perform factory reset.
It will take some time to complete and bring it to rommon.
You will need to load IOS image using USB/TFTP from rommon after
this operation is completed.
DO NOT UNPLUG THE POWER OR INTERRUPT THE OPERATION
Are you sure you want to continue? [confirm]y

設備在操作確認前就有說
You will need to load IOS image using USB/TFTP from rommon after
this operation is completed.
做之前請先詳閱說明書

抱歉,小弟愚笨,還是不太了解如何做,可以麻煩說明清楚一點嗎? 感恩
您好,小弟之前備份的show version資訊如下 :

可以麻煩如何進行安裝OS嗎? 謝謝您 ! ^^

Are you sure you want to continue? [confirm]y

--------------你需要做emergency-install-----------------

  1. 去拿一顆USB,把 你要的版本 .bin file下載下來USB
  2. 接上Switch,然後下指令 emergency-install usbflash0:/cat9k......bin
  3. 他就會安裝了

或是你用tftp,一樣的方式 emergency-install tftp:

emergency-install 不能用的話,改用boot

謝謝Wayne大大,小弟已經成功將設備回復初始狀態了,感恩歐!!! ^^
