1. Within 60 seconds after the instance is started, press <ctrl> + <Break> 3-5 s on the Super Terminal (preferably for a longer time) to enter the rommon mode. The prompt is as follows: rommon1>; 2. rommon1> confreg 0x2142; 3. rommon2> reset to restart the vro; 4.

2. To restore a Cisco IOS Server to a computer, you must install the TFTP Server and ensure that the TFTP Server is running. The computer uses the Server-PT type. 1. Connect the vro and the computer. 2. Start the TFTP service and set the IP address. 3. Start the vro to enter ROM Monitor mode. 4. configure it in Rommon mode, upload the IOS file on the TFTP server to the vro;
Rommon1: IP_ADDRESS = IP address of the router; rommon2: IP_SUBNET_MASK = mask of the router; rommon3: DEFAULT_GATEWAY = gateway, which can be any IP address in the subnet, generally the IP address of TFTP; rommon4: TFTP_SERVER = IP address of the TFTP server; rommon5: TFTP_FILE = Name of the uploaded file, enter the IOS file name of any 2600 series on the TFTP server; rommon6: sync (SAVE); rommon7: set (view); rommon8: tftpdnld (Transfer file). When prompted, select y for a long time. You can see the transfer process without waiting. rommon9: reset.
