How-to Reset Password on Xerox

If you have forgotten a password on a Xerox Workcentre 5225 you won’t find any documentation on Xerox’s website on how to reset the password. If you ask them they will tell you that a technician (who you have to pay) will need to reset it. There is a way around this however. You can enter what is called “debug” mode and reset the password if you have lost the password to the printer (WARNING: Do not try adjusting anything in debug mode that you do not know how to do as it could have negative effects). In order to enter debug mode you will need to hold down the 0 button on the control panel for approximately 5 seconds, then while still holding this down press the start button. You will then be prompted to enter a passcode. The default is “6789”. Now that you are in debug mode you can change the username/password just like you would if you had already logged in as the admin as follows: [more]

  1. Press the <Machine Status> button on the Control Panel.
  2. Press the [Tools] tab.
  3. On the Tools screen press the [Authentication/Security] Settings.
  4. Press [System Administrator Settings].
  5. Press [System Administrator’s Login ID]
  6. On the System Administrator’s Login ID screen, Select [Keyboard]
  7. Type in <username here> for the Login ID, and select [Save]
  8. On the Retype line, select [Keyboard]
  9. Enter the same Login ID, and select [Save] twice.
  10. If prompted [Do you want to change the System Administrator’s Login ID?] select [Yes]
  11. Press [System Administrator’s Passcode].
  12. On the Passcode screen, Select [Keyboard].
  13. Type in <Passcode here> for the [New Passcode], and select [Save].
  14. In [Retype Passcode], select [Keyboard].
  15. Enter the same passcode, and select [Save] twice.
  16. In the [Do you want to change the System Administrator’s Passcode?] screen, select [Yes].
  17. If prompted choose to reboot the machine after the changes have been made.

How to replace failed hard drive on NetApp FAS

How to replace failed hard drive on NetApp FAS


NetApp FAS270, FAS2020, FAS2040, FAS2240, FAS2050


Hard drive has failed and needs replacement.


Disk will have an amber LED on the front of it if it has an issue. You will need a disk of the same capacity as the one you are removing or larger, also make sure disk is the correct type for the shelves that you have.
You can identify failed disks by logging onto the controllers command line via SSH and running the following command:

aggr status -f

-f will identify any of the broken disks.
Output should give you a <disk id> i.e. 0c.00.10

If the LED is not lit in which some cases this can happen, you can illuminate it.

SSH onto the NetApp box and logon (if you haven’t done it already) and switch to advanced mode.

priv set advanced
led_on <disk id identified above>
led_off <disk id identified above>
priv set

Alternatively you can use blink_on & blink_off instead of led_on & led_off.

Remove drive from the shelf and wait for 60 seconds before inserting a new one.

When new drive is in place run the following command to check whether the ID of the disk you have just fitted is owned or not.

disk show -n

If disk auto assign is enabled it’ll be assigned to the head which had the failed disk, if not you will have to do it manually.

disk assign <disk id>

If it won’t accept the command, it might have been auto assigned to the wrong controller/system.  You can clear the assignment from the disk using the following command then try again.

disk assign <disk id> -s unowned -f

The replaced disk will now be assigned as a spare disk to replace the spare which was used when the original failed.
You can check Status of this using following command:

aggr status -s

To check auto disk assign feature use:

options disk auto_assign

The output will either show on or off.
