Recovering from a Lost Password
You can use a local computer (a computer that connects to the Rack PDU or other
device through the serial port) to access the command line interface.
1. Select a serial port at the local computer, and disable any service that uses that
port.
2. Connect the provided serial cable to the selected port on the computer and to
the Serial port at the Rack PDU.
3. Run a terminal program (such as HyperTerminal
®
) and configure the selected
port for 9600 bps, 8 data bits, no parity, 1 stop bit, and no flow control.
4. Press
ENTER, repeatedly if necessary, to display the User Name prompt. If you
are unable to display the User Name prompt, verify the following:
– The serial port is not in use by another application.
– The terminal settings are correct as specified in step 3.
– The correct cable is being used as specified in step 2.
5. Press the Reset button. The Status LED will flash alternately orange and green.
Press the Reset button a second time immediately while the LED is flashing to
reset the user name and password to their defaults temporarily.
6. Press
ENTER, repeatedly if necessary, to display the User Name prompt again,
then use, dell, for the user name and password. (If you take longer than 30
seconds to log on after the User Name prompt is redisplayed, you must repeat
step 5 and log on again.)
7. At the command line interface, use the following commands to change the User
Name and Password settings, both of which are now dell:
user -an yourAdministratorName
user -ap yourAdministratorPassword
For example, to change the Administrator user name to Don Adams, type:
user -an Don Adams
