How to Recover from a Lost Password
You can use a local computer, a computer that connects to the
Management Card or other device through the serial port, to access the
control console.
1. Select a serial port at the local computer, and disable any service that
uses that port.
2. Connect the serial cable (APC part number 940-0024 or 940-1524) to
the selected port on the computer and to the configuration port at the
Management Card.
3. Run a terminal program (such as HyperTerminal
®
) and configure the
selected port as follows:
– 2400 bps
– 8 data bits
– no parity
– 1 stop bit
– 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.
