Resetting Administrator Password
CAUTION: Many repairs may only be done by a certied service technician. You should only 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 PASSWORD_RSET jumper on the CMC board.
The CMC board has a two-pin password reset connector as shown in the following gure. 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 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 PASSWORD_RST jumper on the CMC board.
The PASSWORD_RST jumper uses a two-pin connector as shown in the following gure.
While the PASSWORD_RST 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 PASSWORD_RST jumper is installed, a default serial console conguration is used (rather than conguration
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 move the handle away from 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, you must 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 gure.
