'''Step 1:''' Issue the '''reset <slot_num>'''command from supervisor for the LANE/MPOA board.
<br/><br/>
'''Step 2:''' Hit the '''ESC''' key within 3 seconds.
<br/><br/>
'''Step 3:''' Choose option '''2''', the Modify Jumper Configuration menu item.
<br/><br/>
'''Step 4:''' Answer n to all questions until you see the following line :
DMON jumper .................Disabled. Want to change (y/n/q/e/d)?
'''Step 5:''' Type '''e''' to enable debug monitor mode.
<br/><br/>
'''Step 6:''' To extit the menu type '''q'''
<br/><br/>
'''Step 7:''' Reset the LANE/MPOA board again from the supervisor.
<br/><br/>
'''Step 8:''' Enter the debug monitor '''mwl''' command
The monitor asks for the start address, count and data. Enter the following data (again, you do not need to press Enter):

DMON:> mwl
Start Addr? 20000000
Count? 0006ffff
Data? ffffffff

This erases the NVRAM configurations.
'''Note:''' The count value should not exceed 6ffff. If you type in the wrong value, you can quit this mwl command at any moment by typing q.
<br/><br/>
'''Step 9:''' Type '''q''' or '''f''' to debug the monitor. This takes you through the usual boot programmable read-only memory path.
<br/><br/>
'''Step 10:''' Hit the '''ESC''' key within 3 seconds.
<br/><br/>
'''Step 11:''' Choose option '''2''' to disable the debug monitor jumper.
<br/><br/>
'''Step 12:''' Type '''d''' to disable the jumper.
<br/><br/>
'''Step 13:''' Type '''q''' to quit the menu.
The LANE/MPOA board boots to the Cisco IOS prompt as usual but it does not have a configuration in NVRAM.
You can now reconfigure it as needed.
