Dell PowerVault 725N (Rackmount NAS Appliance) - Manual (Page 32)

Recovering the System
Because your NAS system is designed to have redundancy, it can recover from certain hardware and software failures. In some situations, it can automatically
recover, and in others, you must have administrator privileges and manually intervene to recover the system.
See your System Administrator's Guide for information about recovering the system.
Changing or Clearing the Supervisor Password
Using the System Setup utility, you can change or clear a supervisor password for the BIOS Setup utility. The password is required when the system is booted,
or when the user enters the BIOS Setup utility. A supervisor has access to all features in the BIOS Setup utility.
To change a supervisor password, perform the following steps:
1. Connect a keyboard, monitor, and mouse to the system.
2. Turn on or restart your NAS system.
Press <F2> immediately after you see the following message:
Press <F2> to enter the Function Select menu.
If you wait too long and your operating system begins to load into memory, allow the system to complete the load operation, and then shut down the
NAS system and try again.
3. When the Function Select menu appears, press <1> to run the System Setup utility.
4. From the main menu, select Security.
5. Highlight Change System Password and press <Enter>.
6. Enter the old password in the dialog box that appears.
7. When prompted, enter the new password (no more than six letters or numbers); or, to clear a password, leave this field blank.
8. Press <Enter>.
9. When prompted, select either Setup or Always. If you select Setup, the password will only be requested when entering the System Setup utility. If you
select Always, the password will be requested anytime the system is rebooted.
10. To confirm the new password, enter the password again in the dialog box that appears.
11. Press <Enter>.
Disabling a Forgotten Password
If you forget your supervisor password, you cannot operate your system or change settings in the BIOS Setup utility until you reset the password. To disable
your password, perform the following steps:
1. Turn off the system, including any attached peripherals, and disconnect the system from the electrical outlet.
2. Remove the system cover. See " Removing and Replacing the System Cover ."
3. Move the jumper plug from pin 2 to pins 1 and 2.
The jumper plug, which is labeled J5 on the system board, is located next to the DIMMs and the power supply.
4. Replace the system cover, connect the system to the electrical outlet, and turn on the system.
The password clears.
5. Turn off the system, including any attached peripherals, and disconnect the system from the electrical outlet.
6. Remove the system cover. See " Removing and Replacing the System Cover ."
7. Move the jumper plug back to its original position.
8. Replace the system cover, connect the system to the electrical outlet, and turn on the system.
The system does not have password protection. See your User's Guide for information about setting the password.

NOTE: The system password is disabled by default. Because the password is required to enter the BIOS Setup utility, do not enable it unless security is
a concern.
NOTE: When you turn on the system, press the power button for less than two seconds. If you press the power button for longer than 3 seconds, the
NAS system shuts down and automatically rebuilds its RAID arrays, which could impact system performance for several hours.
