Reset switch to factory-default setting:
When users forget the login profile or password, they're unable to login the switch
again. The only way to login to the switch is to reset the switch to factory-default and
use the default user name (admin) and password (1234) to login.
Procedure to reset switch to factory-default login profile:
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 Switch as shown below.
Side Panel: GS1920-48
Side Panel: GS1920-24, GS1920-24HP, GS1920-48HP
2. Press the button for more than five seconds until 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 configuration again, you may
change your IP address of your computer to be in the same subnet as that of
the default Switch IP address (192.168.1.1).
3. User can now login with default user-name and password.
