How to Recover From a Lost

Password

You can use a local computer, a computer that

connects to the PDU 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 (940-0144) to the

selected port on the computer and to the

configuration port at the PDU.

3. Run a terminal program (such as

HyperTerminal) and configure the selected

port as follows:

9600 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.

6. Press

ENTER as many times as necessary to

redisplay 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 redisplayed,

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, and restart any service

you disabled.
