You could lock yourself (and all others) out from the switch by:
1 Deleting the management VLAN (default is VLAN 1).
2 Deleting all IP routing domains.
3 Deleting all port-based VLANs with the CPU port as a member. The “CPU port” is the
management port of the switch.
4 Filtering all traffic to the CPU port.
5 Disabling all ports.
6 Assigning minimum bandwidth to the CPU port. If you limit bandwidth to the CPU port,
you may find that the switch performs sluggishly or not at all.
Note: Be careful not to lock yourself and others out of the switch.
4.5 Resetting the Switch
If you lock yourself (and others) from the switch or forget the ES-4024A password, you will
need to reload the factory-default configuration file or reset the switch back to the factory
defaults.
4.5.1 Reload the Configuration File
Uploading the factory-default configuration file replaces the current configuration file with the
factory-default configuration file. This means that you will lose all previous configurations
and the speed of the console port will be reset to the default of 9600bps with 8 data bit, no
parity, one stop bit and flow control set to none. The password will also be reset to “1234” and
the IP address to 192.168.1.1.
To upload the configuration file, do the following:
1 Connect to the console port using a computer with terminal emulation software. See
Section 3.1.1 on page 41 for details.
2 Disconnect and reconnect the switch’s power to begin a session. When you reconnect the
switch’s power, you will see the initial screen.
3 When you see the message “
Press any key to enter Debug Mode within 3
seconds ...
” press any key to enter debug mode.
4 Type atlc after the “
Enter Debug Mode” message.
5 Wait for the “
Starting XMODEM upload” message before activating XMODEM
upload on your terminal.
6 After a configuration file upload, type
atgo to restart the switch.
