Forgot or Lost Password

If you have forgotten the administration password you can return the switch to its
factory default state by following these steps:

2. Remove all cables from the front-panel ports.
3. Connect port 1 to port 2 on the front panel, using a standard network cable.
4. Reconnect the power cord to the rear of the switch.
5. Wait at least 40 seconds before disconnecting port 1 from port 2.
After completing this procedure, the password will be "admin" and the network
address will be returned to the default; 192.168.2.10.
