How to 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 (990-0144) 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 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.)
