Let’s say you purchase a couple of 300s on the Ebay and someone forgot to reset config but you can’t get in as all default passwords got changed. Here’s what we need to do:
\n
\n1. Connect to the serial console port of the switch (make sure to use correct Brocade cable as typical Cisco console cable will not work).
\n2. Power on switch
\n3. When promted to stop test or stop AutoBoot, press ESC.
\nThe Boot PROM menu is displayed with the following options:
\n\u2022 Start system
\nUsed to reboot the system.
\n\u2022 Recover password.
\nUsed to generate a character string for your support provider to recover the Boot PROM
\npassword. Use this feature only when directed by technical support personnel.
\n\u2022 Enter command shell.
\nUsed to enter the command shell, to reset all passwords on the system.
\nChecking system RAM - press any key to stop test
\nChecking memory address: 00100000
\nSystem RAM test terminated by keyboard
\nset_bootstatus: BS_LOAD_OS, platform_idx = 6
\nHit ESC to stop autoboot: 0
\n1) Start system.
\n2) Recover password.
\n3) Enter command shell.
\nOption?<\/code>
\n4. Type 3 at the prompt to open the command shell:
\nOption? 3
\n5. Type the Boot PROM password, if prompted, and press Enter.
\nThe Boot PROM has a password only if one was defined.
\nNOTE
\nIf you are prompted to enter a new Boot PROM password, make sure it is at least 8 characters
\nin length. Do not select this option unless specifically instructed by support personnel.
\n6. To change the \u201cOSLoadOptions=quiet;quiet\u201d setting so that the switch boots into single user
\nmode, enter the following command:
\nFabric OS Password Recovery Notes 9
\n53-1000114-05
\nPassword recovery using the Boot PROM interface 1<\/code>
\n=> setenv OSLoadOptions “single”<\/strong>
\n7. Enter the printEnv command to verify the change:
\n=> printenv<\/strong>
\nAutoLoad=yes
\nBootromVerbose=no
\nInitTest=MEM()
\nLoadIdentifiers=Fabric Operating System;Fabric Operating System
\nOSLoadOptions=single
\n(output truncated)<\/code>
\n8. Save the changes:
\n=> saveenv<\/strong>
\nSaving Environment to Flash…..Done
\n9. Enter the boot command with no parameters to bring up the device in the single user mode:
\n=> boot<\/strong>
\nMap file at LBA sector 0x17da68
\n## Booting image at 00400000 ...
\n(output truncated)<\/code>
\n10. Enter the mount command with the following parameters to remount the root partition as
\nread\/writecapable:
\nsh-2.04# mount -o remount,rw \/<\/strong>
\nEXT3 FS on hda1, internal journal<\/code>
\n11. Mount the secondary partition.
\nIf the previous command returns hda2, then use hda1 in this command. If the previous
\ncommand returns hda 1, use hda2.
\nsh-2.04# mount \/dev\/hda2 \/mnt<\/strong>
\nkjournald starting. Commit interval 5 seconds
\nEXT3 FS on hda2, internal journal
\nEXT3-fs: mounted filesystem with ordered data mode.<\/code>
\n12. Enter the passwddefault command to reset all passwords to default values as follows:
\nsh-2.04# \/sbin\/passwddefault<\/strong>
\nAll account passwords have been successfully set to factory default.
\nIf additional user accounts existed, they are deleted. Only the default accounts and passwords
\nremain.<\/code>
\n13. Reset the OSLoadOptions to \u201cqueit;quiet\u201d:
\nsh-2.04# bootenv OSLoadOptions \u201dquiet;quiet\u201d<\/strong>
\n14. Reboot the switch using the reboot \u2013f command.
\nsh-2.04# reboot -f<\/strong>
\nTraffic flow resumes when the switch completes rebooting. If you do not use the \u2013f option you
\nwill have to manually reboot the switch.
\n15. Log in with admin account using default password.
\nThe password recovery procedure is now complete.<\/p>\n

Next, we need to reset configuration to factory default:<\/p>\n

1. Disable switch
\n>switchdisable<\/strong>
\n2. Disable config
\n>cfgdisable<\/strong> (hit “y” at prompt)
\n3. Clear config
\ncfgclear<\/strong> (hit “y” at prompt)
\n4. Save clean configuration
\n>cfgsave<\/strong> (hit “y” at prompt)
\n5. Reset configuration to default
\n>configdefault<\/strong> (hit “Y” at prompt)
\n6. Re-enable switch
\n>switchenable<\/strong>
\n7. Reboot to activate changes
\n>reboot<\/strong><\/p>\n

And finally we need to change management IP address with the following command
\n>ipaddrset<\/strong><\/p>\n

This procedure was tested with Fabric OS 7.4.1c
