Forgotten IP Address or Password
If you have forgotten the switch’s IP address or administration password you
can return the switch to its factory default state by following these steps:
1. Remove the power cord from the back of the switch.
2. Connect port 1 to port 2 on the front panel, using a standard network cable.
3. Reconnect the power cord to the rear of the switch.
4. Wait at least 40 seconds before disconnecting port 1 from port 2.
After completing this procedure, the password will be empty, the network
address will be returned to the default 192.168.2.10, and all configuration
settings will be returned to the original factory defaults.
Testing the Switch by Resetting It
If you believe the switch is not operating correctly, you can reset the switch
to test its circuitry and operating code. To reset a switch, unplug and plug in
the power cord (power cycling)
Power cycling the switch cause the switch to perform its power-on self test.
