Or you could try...

1) First, you must be attached to the GRF via  the console port. It is not 
possible to telnet into the unit to recover the root password.

2) Then boot the unit in single mode. During the boot sequence you will see

the following line:
pci0 at root: configuration mechanism 1

Start hitting control-c at this point. Messages will being scrolling by very 
rapidly until a line appears that asks which shell you would like.

Hit return.

3) Mount the internal flash drive.
#mount -w /dev/wd0a /flash

4) Change the master.passwd file in the flash directory
#cd /flash
#cd /etc.A_X_X_X,default        (Where A_X_X_X is your current sw version)
#vi master.passwd
 the following line will appear:
root:Jf83vkLw3.w9:0:0::0:0:System Administrator:/root:/bin/ksh
     ^^^^^^^^^^^^remove this
The line below shows what you want it to look like:
root::0:0::0:0:System Administrator:/root:/bin/ksh

5) Update the database so the change is accepted.
#pwd_mkdb -d master.passwd

6) Unmount the flash drive
#umount /flash

7) #reboot
