Serial Cable

Switch end, modem 9pin D female to 25 pin male, plugged in to 25p f to 9p female adapter.


Default passwords for the ‘root’ and ‘admin’ accounts:

  • fibranne
  • fibreanne
  • password
  • default

Reset Passwords

Completely untested solutions.

I found something interesting in the internet. A person used the "go to adrs" option to boot into the system without asking 
for password. 
But the system is not the same as mine. After booting to the adress from the OSLoader entry he mounted the drive with:-
mount -o remount,rw,noatime /

Then he did: mount /dev/hda2 /mnt

and finaly he resetted the password with: /mnt/sbin/passwddefault

with a: reboot -f

Or Try ADMIN as user no password, worked on mine

A list below show Switches Username and Password by Default.

For all switch listed in this list, excepted I/O Module ( former Blade Switch )

  for username admin , user = password
  for username root = fibranne

For I/O Module

  Initial default user ID = USERID
  password = PASSWORD

Question such as password recovery, see Contribution's below

1. Connect the serial console to the SAN switch (or  director). (Default serial console settings:-
   Baud rate€“ 9600, Data  bits 8, Parity€“ none, Stop bits -1, Flow control none).

2. Reboot the switch
3. Press ESC at the message “Hit ESC to stop autoboot:€œ, 
the Boot PROM menu displays with the following options:

1) Start system.

2) Recover password.
3) Enter command shell.

4. Type “3€” to Enter Command shell.

1) Start system.

2) Recover password.

3) Enter command shell.

Option? 3

Boot PROM password has not been set.

5. Run the "printenv"€ command to check the environment variables (This step is optional).

⇒ printenv

LoadIdentifiers=Fabric Operating System;Fabric Operating System

6. Set the environment variable “€œOSLoadOptions” to single

⇒ setenv OSLoadOptions=single

7. Run the command œauto

⇒ auto

8. After the switch boot in single user mode, remount the / partition as read/write:
sh-2.04# mount -o remount,rw,noatime /
9. Mount the second partition to /mnt (this will get from the value of "€œOSRootPartition"€ 
  variable in "€œprintenv" output€“ 
  usually it  will be "€œhda2", that is, /dev/hda2)
sh-2.04# mount /dev/hda2 /mnt
10. Verify the mounted file systems by running the "€œmount"€ command:
sh-2.04# mount
/dev/root on / type unknown (rw,noatime)
none on /proc type proc (rw)
none on /dev/pts type devpts (rw,mode=620)
none on /tmp type ramfs (rw)
/dev/hda2 on /mnt type ext3 (rw)
11. Run the "œpasswddefault"€ command as follows:

sh-2.04# /sbin/passwddefault

12. Reboot the switch.

sh-2.04# reboot

After this steps, I can logged in to switch via root/fibranne
