How to Recover From a Lost Password
You can use a local computer that connects to the PDU through the serial
port on the front panel of the unit.
1. Select a serial port at a local computer, and disable any service that
uses the port.
2. Use the configuration cable (940-0144) to connect the selected port
to the serial port on the front panel of the
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, and save the changes.
4. Press
ENTER to display the User Name prompt.
5. Press the Reset button on the
PDU, which causes the PDU to restart,
a process that typically takes approximately 15 seconds.
6. Press
ENTER as many times as necessary to redisplay the User
Name prompt, then use 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 start the login procedure again at
step 4.)
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 and log off.
Note
Reconnect any cable that you disconnected in step 2 and
restart any service that you disabled in step 1.
