You forget the password for the "admin" user account and can no longer perform important management operations.
Use the password recovery method outlined below to define a new password for the "admin" user account:
You must use the console port to recover the passsword. If you attempt the recovery method using the network, the password will be rejected.
You cannot use a soft reset operation to reset the password of the "admin" user account. This will end the password recovery procedure and return you to the CLI login prompt.

The resetting of the password requires the installation of a console cable to the console port.
Be sure the terminal emulator program is set to VT-100 management using compatible, 38400 baud rate, no parity, 8 data bits and Console connection one stop bit.
Use the included cable, or be sure that the pin-out complies with a standard null-modem cable
Once the cable is connected, reboot the switch. Type a Ctrl/C until you enter the failsafe mode. This will be denoted with the prompt: “CFE>”
At the prompt execute the following commands:
CFE> reset -sysreset
At this point the password has been reset.

If it's the Power Plus (3C16475BS) model, there should be a reset button inside a small hole on the back. "10 - Recovery Button" Inserting a paperclip or similar to reset. If it's not the Power Plus model and is in fact (3C16475A), this is an unmanaged switch, with no administrative capabilities. You don't need a password.

First,"There is usually a small button on routers that can be accessed with the tip of a pen or a paperclip. When you find that tiny button, hold your pen or paperclip down on it for approximately 10 seconds until the router resets itself to factory defaults."
After that, you can contact the manufacturer to get some helps if you still have problem.
