Unfortunately you cannot without losing your settings. That's why 3Com recommends you should save all your settings at an external location.
Here are instructions I used the last time I had to recover a lost password



You cannot retrieve a lost administrator password from the Firewall. However, when the firmware has been erased, you can use a basic web management interface to get the Firewall up and running again. The Firewall reverts to its default IP address of 192.168.1.254 after a complete reset, so you must reconfigure your chosen management station to an IP address in the same subnet to access the management interface (for example, 192.168.1.200).

CAUTION: The reset procedure described below not only deletes all the settings from your Firewall, but also erases the current copy of the firmware from the unit. For this reason, 3Com recommends that you save your firewall settings on a regular basis, and that you also have a copy of the latest firmware available locally. A copy is available on the companion CD and 3Com.com to get you up and running again.

Step 1: Reset the Firewall to factory defaults:
1 Disconnect the power from the Firewall.
2 Using a blunt pointed object, fully press in the reset button on the back panel.
3 While holding the reset button in, reconnect the power to the unit.
4 Continue holding the reset button in until the Alert LED starts flashing. This should be approximately 10 seconds.
5 When the Alert LED stops flashing, the reset is complete. You can now release the reset button.
When the reset is complete, the Internet Firewall restarts.
The Power LED stops flashing and the Alert LED is illuminated continuously, indicating that the unit has been reset and the firmware erased.
However, if it is no longer possible to access the web management interface (for example, due to a lost password), then you must completely reset your Firewall.

CAUTION: The reset procedure described below not only deletes all the settings from your Firewall, but also erases the current copy of the firmware from the unit. For this reason, 3Com recommends that you save your Firewall settings on a regular basis, and that you also have a copy of the latest firmware available locally. A copy is available on the companion CD to get you up and running again.

Step 2: Reload the firmware:
1 Type http://192.168.1.254 into the web browser on the management station, and press Enter. The basic management interface loads.
Make sure that you are using the browser that supports HTML uploads, otherwise you cannot upload the firmware.
2 In the box labeled Please select a firmware file, type in the full file and path name of the firmware image that you want to upload to the unit. Use the Browse button to
locate the file if you are not sure of its location.
3 Once you have located the file, click Upload to upload the firmware. This process takes approximately one minute. Once complete, the firewall restarts automatically, and the message shown in Figure 54 is displayed.
