Upgrading Firmware through a Serial Connection

An administrator can use a local computer that connects to the Rack PDU through the

serial port, on the front panel of the unit, to upgrade the firmware for the Rack PDU.

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

port.

2. Use the supplied serial cable (APC part number 940-0144A) 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) 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.

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.
