===== Resetting all passwords on a Brocade Fabric Switch =====

1) If the switch is powered on, shut it down.

2) Connect your computer to the switch’s serial port with a serial null modem cable, and
with a terminal emulation program, open up the associated COM port.

3) Power up the switch.

4) As the switch boots up, POST messages will be displayed. Immediately after this
message is displayed on the screen **Press escape within 4 seconds to enter boot
interface** press escape, then press 3 to **Enter Command Shell**\\
System RAM test using Default POST RAM Test succeeded.\\
Press escape within 4 seconds to enter boot interface.
  1. Start system.
  2. Recover password.
  3. Enter command shell.
   Option? 3

5) Run the ‘printenv’ command and take note of the values for OSLoader and OSRootPartition:
<cli prompt='>'>
> printenv
AutoLoad=yes
ENET_MAC=00051E025A38
InitTest=MEM()
LoadIdentifiers=Fabric Operating System;Fabric Operating System
OSLoadOptions=quiet
OSLoader=ATA()0×259c0;ATA()0×629e0
OSRootPartition=hda1;hda2
SkipWatchdog=yes
</cli>

6) Using the first value of OSLoader, run **boot <1st OSLoader> -s**:
<cli prompt='>'>
> boot ATA()0×259c0 -s
Booting “Manually selected OS” image.
Entry point at 0×01000000 ...
</cli>

7. The switch will then continue booting to the OS. Once at the “#” prompt, run
<cli prompt='#'>
sh-2.04# mount -o remount,rw,noatime /
EXT3 FS 2.4-0.9.17, 10 Jan 2002 on ide0(3,1), internal journal
</cli>

8. Next, take the second value of OSRootPartition and mount the device as /mnt:
<cli prompt='#'>
sh-2.04# mount /dev/hda2 /mnt
kjournald starting. Commit interval 5 seconds
EXT3 FS 2.4-0.9.17, 10 Jan 2002 on ide0(3,2), internal journal
EXT3-fs: recovery complete.
EXT3-fs: mounted filesystem with ordered data mode.
</cli>

9. Now run the password reset script **/mnt/sbin/passwddefault**:
<cli prompt='#'>
sh-2.04# /mnt/sbin/passwddefault
</cli>
All account passwords have been successfully set to factory default.

10. Finally reboot the switch with **reboot -f**:
<cli prompt='#'>
sh-2.04# reboot -f
</cli>
flushing ide devices: hda
Restarting system.

11. After the reboot, the password for the **admin** user account is **password**. Once you log in for the first time, you will be prompted to change the passwords for the root,
factory, admin and user accounts

INFO: it's also possible to switch to single user mode (persistent) and revert back to quiet before the last reboot:
  => printenv
  OSLoadOptions=quiet;quiet
  => setenv OSLoadOptions "single"    
  => saveenv
  => boot
  ....mount and reset password
  sh-2.04# bootenv OSLoadOptions "quiet;quiet"
  sh-2.04# reboot -f

For info: with printenv, you'll see the **IP address assigned** to the switch
