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 940-0103) to the selected port on the computer and
to the console port on the
PDU monitoring unit.
3. Run a terminal program (such as HyperTerminal
®
) on your computer 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 terminal settings are correct as specified in step 3.
– The correct cable is being used as specified in step 2.

immediately while the LED is flashing to reset the user name and password to their defaults
temporarily.

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.)
