Use XMODEM to upgrade one PDU
To upgrade the firmware for one PDU that is not on the network, you must extract the firmware files
from the firmware upgrade tool (see “To extract the firmware files:” on page 101).
To transfer the files:
1. Obtain the individual firmware modules (the AOS module and the application module) from
www.apc.com/tools/download.
2. Select a serial port at the local computer and disable any service that uses the port.
3. Connect the provided configuration cable to the selected port and to the serial port at the PDU.
4. 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.
5. Press
ENTER to display the User Name prompt.
6. Enter the Administrator user name and password (apc by default for both).
7. From the command line interface menu, select System, then Tools, then File Transfer, then
XMODEM; and type
Yes at the prompt to continue.
8. Select a baud rate, change the terminal program’s baud rate to match your selection, and press
ENTER. A higher baud rate causes faster upgrades.
9. From the terminal program’s menu, select the binary AOS file to transfer using XMODEM-CRC.
After the XMODEM transfer is complete, set the baud rate to 2400. The PDU automatically
restarts.
10.Repeat step 4 through step 9 to install the application module. In step 9, use the application
module file name, not the AOS module file name.
11.For information about the format used for firmware modules, see “Firmware files (PDU)” on
page 101.
