8 Change a service port number but forget it.
9 You forgot to log out of the Switch from a computer before logging in again on another computer.
Note: Be careful not to lock yourself and others out of the Switch.
4.6 Resetting the Switch
If you lock yourself (and others) from the Switch or forget the administrator password, you will need to
reload the factory-default configuration file or reset the Switch back to the factory defaults.
4.6.1 Press the Reset Button
If you forget your password or cannot access the Web Configurator, you will need to use the Reset
button at the side of the device to reload the factory-default configuration file. This means that you will
lose all configurations that you had previously and the default Switch IP address, user name and
password will be reset to 192.168.1.1, admin and 1234 respectively.
If you backed up an earlier configuration file as advised in Section 1.3 on page 24, you will not have to
totally re-configure the Switch after resetting. You can simply restore your last configuration.
Follow the steps below to reset the Switch back to factory defaults.
1 Make sure the SYS LED is steady green (not blinking). Use a pointed instrument such as a pin to access
the Reset button on the side of the Switch as shown in Section 4.6.1.1 on page 42.
2 Press the button for more than five seconds until the SYS LED begins to blink and then release it. Wait for
the Switch to restart (the SYS LED will be steady green again). This takes up to two minutes.
Note: If you want to access the Switch web configurator again, you may need to change the
IP address of your computer to be in the same subnet as that of the default Switch IP
address (192.168.1.1).
4.6.1.1 Side Panels
The reset button is located at the side of the Switch as shown.
