1. Restore Factory Settings
1.1 Networking Requirements
Need to clear the existing configuration of the device and restore the factory default settings.
1.2 Configuration Points
After restoring the factory settings, the original configuration will be cleared. If the configuration is more important, please backup the
configuration first;
If the router's WEB interface fails to log in, you need to use the console line to restore the factory through the command line;
After restoring the factory settings, the default IP of the 0/MGMT interface is 192.168.1.1, and the user name and password are both
admin;
1.3 Configuration Steps
1.3.1 Restore Factory Settings by Command Line
Log in to the device command line through telnet or hyper terminal.

1.4 Configuration Verification
After restoring the factory settings, configure a computer with an IP of 192.168.1.10 and a subnet mask of 255.255.255.0 and a gateway of
192.168.1.1. Connect this computer to the device's 0/MGMT port;
Open the computer to run, enter cmd, enter ping 192.168.1.1 in the pop-up window to see if it can be pinged, if it can be pinged, the
recovery is successful;
C:\Users\FS>ping 192.168.1.1
Ping 192.168.1.1 has 32 bytes of data:
Reply from 192.168.1.1: byte=32 time=2ms TTL=64
Reply from 192.168.1.1: byte=32 time=2ms TTL=64
Reply from 192.168.1.1: byte=32 time=3ms TTL=64
Reply from 192.168.1.1: byte=32 time=2ms TTL=64
Ping statistics of 192.168.1.1:
Packet: Sent = 4, Received = 4, Lost = 0 (0% lost),
Estimated time of round trip (in milliseconds):
Shortest = 2ms, longest = 3ms, average = 2ms
2. Password Recovery
*Notes on password recovery
When doing password recovery, please prepare the console line first.
Password recovery needs to restart the device, which will cause network disconnection. Please perform password recovery when it
is convenient to disconnect the network;
If the administrator himself has forgotten the web management password of the gateway device and cannot log in through the
web, then he can enter the CTRL layer through the configuration line for password recovery, and the previous configuration
information can be retained;
