+
+ Load the U-Boot prompt. This can be done by hitting any key right after the appearance of the U-Boot banner:
+ {{{
+U-Boot 1.1.2 (Feb 25 2006 - 21:16:55)
+
+Board: Netgear GSM7248

+Hit any key to stop autoboot:  0 
+ }}}
+ The variables for the switch should look like something below:
+ {{{
+=> printenv
+flashargs=setenv bootargs root=/dev/ram console=ttyS0,9600 mem=62M mac0=$(fp_card_base_mac) serialnum=$(fp_sn) quiet

+fp_model=Netgear GSM7248
+fp_mfgr=bc00
+fp_pn=GSM7248
+fp_fru=GSM7248
+fp_desc=Netgear GSM7248
+fp_maint=1
+fp_who=LVL7 Support

+fp_sn=1DU3823J00054
+stdin=serial

+stderr=serial
+
+Environment size: 496/65532 byte
+ }}}
+
+ The `flashargs` variable for `bootcmd` load the firmware with the current settings, including the password. You want to start the firmware without these settings so you can get to the boot menu. To do this, run the `bootm` command directly:
+ {{{
+=> bootm ff000000
+ }}}
+
+ This loads just the firmware of the switch. Let the startup process run its course. Choose 2 when prompted for the startup mode:
+ {{{
+Select startup mode.  If no selection is made within 3 seconds,
+the GSM7248 Application will start automatically...
+
+1 - Start GSM7248 Application
+2 - Display Utility Menu
+Select (1, 2): 2
+ }}}
+
+ This will present you with the familiar boot menu:
+ {{{
+GSM7248 Startup Rev: 3.3
+
+GSM7248 Startup -- Utility Menu
+
+ 1  - Start GSM7248 Application
+ 2  - Load Code Update Package using XMODEM/YMODEM/ZMODEM
+ 3  - Display Vital Product Data
+ 4  - Select Serial Speed
+ 5  - Retrieve Error Log using XMODEM/YMODEM/ZMODEM
+ 6  - Erase Current Configuration
+ 7  - Erase Permanent Storage
+
+ Q  - Quit from GSM7248 Startup
+
+Select option (1-8 or Q):
+ }}}
+ Enter 6 to reset the configs. Now, power cycle the switch. The switch should be in default mode when it comes up again:
+ {{{
+GSM7248 starting...started!
