Upgrading Firmware through a Serial Connection

For a complete description of how to download a firmware upgrade for your Rack PDU, see Upgrading Firmware: Methods and Tools. That section also explains how to use network-based file transfer tools, which complete a firmware upgrade more quickly than the XMODEM protocol described here, which uses a serial connection.

You can use a local computer that connects to the Rack PDU through the serial port on the front panel of the unit.

1.Select a serial port at the local computer, and disable any service which uses that port.

2.Use the supplied serial cable (940-0144) to connect the selected port to the serial port on the front panel of 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. Save the changes.

4.Press ENTER, repeatedly if necessary, to display the User Name prompt.

5.Enter your user name and password (both apc, by default, for administrators only) and press the ENTER key.

6.From the Control Console menu, select, in order, System, Tools, File Transfer, and XMODEM.

7.At the prompt Perform transfer with XMODEM-CRC?type YES, and press ENTER.

8.The system will then prompt you to choose a transfer rate and to change your terminal settings to match the transfer rate. Press ENTER to set the Switched Rack PDU to accept the download.
