Recover From a Lost Password
To access the control console, you can use a local computer (a computer that connects to the Network
Management Card or other device through the serial port).
1. Select a serial port at the local computer, and disable any service that uses that port.
2. Use the configuration cable to connect the selected port to the serial port (J2) on the controller
board. The controller board is in the right compartment of the electrical panel.
Electrical Hazard: Potentially dangerous and lethal voltages exist within the
electrical cabinet. Do not touch components on the electrical panel other than the serial
port.
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 on the faceplate of the Network Management Card. 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 as many times as necessary to re-display the User Name prompt, then use the
default, apc, for the user name and password. (If you take longer than 30 seconds to log on after
the User Name prompt is re-displayed, you must repeat step 5 and log on again.)
7. From the Control Console menu, select System, then User Manager.
8. Select Administrator, and change the User Name and Password settings, both of which are
now defined as apc.
9. Press
CTRL+C, log off, reconnect any serial cable you disconnected, restart any service you
disabled, close all panels, and re-install doors.
