How to Recover From a Lost Password

You can use a local computer, a computer that connects to the Network 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.Use the configuration cable (940-0103) 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.

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 NetworkAIR IR In-row Air Conditioner. 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.

Do not touch components on the electrical panel, other than the serial port.
