Resetting Forgotten Administrator Password

  • CAUTION: Many repairs may only be done by a certified service technician. Perform troubleshooting and simple repairs as authorized in your product documentation, or as directed by the online or telephone service and support team. Damage due to servicing that is not authorized by Dell is not covered by your warranty. Read and follow the safety instructions that came with the product.

To perform management actions, a user with Administrator privileges is required. The CMC software has a user account password protection security feature that may be disabled if the administrator account password is forgotten. If the administrator account password is forgotten, it can be recovered using the J_PWORD jumper on the CMC board.

The CMC board has a two-pin password reset connector as shown in the following figure. If a jumper is installed in the reset connector, the default administrator account and password is enabled and set to the default values of username: root and password: calvin. The administrator account is reset regardless if the account has been removed, or if the password was changed.

  • NOTE: Make sure that the CMC module is in a passive state before you begin.

To perform management actions, a user with Administrator privileges is required. If the administrator account password is forgotten, it can be reset using the J_PWORD jumper on the CMC board.

The J_PWORD jumper uses a two-pin connector as shown in the following figure.

While the J_PWORD jumper is installed, the default administrator account and password is enabled and set to the following default values:

username: root

password: calvin

The administrator account is temporarily reset regardless if the administrator account was removed, or if the password was changed.

  • NOTE: When the J_PWORD jumper is installed, a default serial console configuration is used (rather than configuration property values), as follows:

cfgSerialBaudRate=115200

cfgSerialConsoleEnable=1

cfgSerialConsoleQuitKey=^\

cfgSerialConsoleIdleTimeout=0

cfgSerialConsoleNoAuth=0

cfgSerialConsoleCommand=""

cfgSerialConsoleColumns=0

  1. Press the CMC release latch on the handle and pull the module front panel. Slide the CMC module out of the enclosure.
    • NOTE: Electrostatic discharge (ESD) events can damage CMC. Under certain conditions, ESD may build up on your body or an object, and then discharge into your CMC. To prevent ESD damage, take precautions to discharge static electricity from your body while handling and accessing CMC outside the Chassis.
  2. Remove the jumper plug from the password reset connector, and insert a 2-pin jumper to enable the default administrator account. To locate the password jumper on the CMC board, see the following figure. Password Reset Jumper Location
    Table 1. CMC Password Jumper Settings . The following table lists the CMC password jumper locations.
    J_PWORDpassword reset disabled(default)The password reset feature is disabled.
     password reset enabled The password reset feature is enabled.
  3. Slide the CMC module into the enclosure. Reattach any cables that were disconnected.
    • NOTE: Make sure that the CMC module is active until the remaining steps are completed.
  4. Wait for the CMC to finish rebooting. In the web interface, in the system tree, go to Chassis Overview and click Power > Control, select the Reset CMC (warm boot), and click Apply.
  5. Log into the active CMC using the default administrator username: root and password: calvin, and restore any necessary user account settings. The existing accounts and passwords are not disabled and are still active.
  6. Perform the required management actions, including creating an administrator password.
  7. Remove the 2-pin J_PWORD jumper and replace the jumper plug.
    1. Press in the CMC release latch on the handle and pull the module front panel. Slide the CMC module out of the enclosure.
    2. Remove the 2-pin jumper and replace the jumper plug.
    3. Slide the CMC module into the enclosure. Reattach any cables that were disconnected. Repeat step 4 to make the unjumpered CMC module the active CMC.
