There are two main methods to return a
Cisco router to its original factory defaults. These two methods are described below.
Method 11. uses the config-register 0x2102 command in global configuration mode.
2. Check the configuration register on the router by issuing the show version command.
3. The configuration register setting is displayed in the last line of the show version command output and should be set to 0x2102. If this is not the case, enter the config-register 0x2102 command once in global configuration mode.
router#configure terminalrouter(config)#config-register 0x2102router(config)#endrouter#4. If the show version command is issued again, the same line in the command output will have '(will be 0x2102 at next reload)' appended to the current register setting.
5. Erase the current start-up configuration on the router with the write erase command.
Reload the router with the reload command. When prompted to save the configuration, DO NOT save.
router#reloadSystem configuration has been modified. Save? [yes/no]: n
Proceed with reload? [confirm]
Once the router reloads, the System Configuration Dialog appears.
--- System Configuration Dialog ---
Would you like to enter the initial configuration dialog? [yes/no]:
The router is now reset to the original factory defaults.
Method 21. uses the config-register 0x2142 command in global configuration mode.
2. Enter the config-register 0x2142 command in global configuration mode.
router(config)#config-register 0x2142
This causes the router to ignore the start-up configuration on the next reload. If a show version is issued, the last line in the command output will have '(will be 0x2142 at next reload)' appended to the current configuration register setting.
3. Reload the router using the reload command in enable mode. It is not necessary to save when prompted to save the system configuration.
router#reloadSystem configuration has been modified. Save? [yes/no]: n
Proceed with reload? [confirm]
After the router has reloaded, the System Configuration Dialog appears.
4. Enter no to the question "Would you like to enter initial configuration dialog?"
5. Change the configuration register setting to 0x2102 by entering the config-register 0x2102 command once in global configuration mode.
6. Issue the write memory command in enable mode to overwrite the existing start-up configuration with the current running configuration.
7. Reload the router with the reload command in enable mode.
Once the router reloads, the System configuration Dialog appears.
--- System Configuration Dialog ---
Would you like to enter the initial configuration dialog? [yes/no]:
The router is now reset to the original factory defaults.
Note: The configurations below are stored in ROMMON, and cannot be reset to Factory Default Settings by the write erase or config-register 0x2142 commands.

I'll answer my own question:
Turns out that there is no magic "hold the reset button while powering on the switch" to get everything back to the factory defaults like there is on most other manufacturer's switches.
But all is not lost - a call to A-T's tech support ((800) 428-4835) with the MAC address of the switch will enable them to look up a "backdoor admin password". I was able to use this backdoor password to reset the real manager password.
Um, maybe I should be one fo the experts here? ;-)

I have the a problem with my AT8024GB switch, I cannot log in to the swicth using the default password. Maybe the switch is not factory default but i tried to reset the switch with the button on the back side of the switch and still I'm not able to login.
I donr rememebr tne user name and passwrd and now i need to restart on factory default, how can i do this?
