Metered Rack PDU

Recover 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 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 940-0144A) to the selected port on
the computer and to the configuration 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 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.
10. Select Accept changes.
