UPS Network management card – password reset

Just had to reset an APC Ap9617 management card the other day, found out, this was a bit tricky, especially when the guides found, showed that the baudrate had to be 9600, but 2400baud was the correct speed, here is the way to do it 🙂


You can use a local computer, a computer that connects to the Management Card or

other device through the serial port, to access the control console.

1. At the local computer, select a serial port, and disable any service that uses it.

2. Connect the serial cable from the selected port on the computer to the

configuration port at the UPS Network Management Card or at the APC S Type

Power Conditioner with Battery Backup:

• For an APC UPS, use the provided serial cable (APC part number 940-0024) or

the longer serial cable that you can order (APC part number 940-1524).

• For an APC S Type Power Conditioner with Battery Backup, use the provided

industry-standard RS-232 serial cable (APC part number 940-1000B.)

3. Run a terminal program (such as HyperTerminal®) and configure the selected

port for 2400 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.
