Use XMODEM to upgrade one Automatic Transfer Switch
To use XMODEM to upgrade the firmware for a single Automatic Transfer
Switch that is not on the network:
1. Obtain the individual firmware modules (the AOS module and the
application module) from the support section of the APC Web site
www.apc.com/tools/download.
2. Select a serial port at the local computer, disable any service which
uses that port, and connect the smart-signaling cable that came with
the Automatic Transfer Switch to the selected port and to the serial port
at the Automatic Transfer Switch.
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, and save the changes.
4. Press
ENTER to display the User Name prompt.
5. Enter your Administrator user name and password. The default for
both is apc.
6. Start an XMODEM transfer:
You cannot upgrade the AOS firmware module of any APC device
directly from firmware version 1.x.x to 2.1.0 or later. The upgrade
attempt will fail.
To upgrade the AOS firmware module of an APC device from version
1.x.x to 2.1.0 or later, first upgrade the module to the latest available
version 2.0.x AOS firmware module. Then upgrade it again, this time
from version 2.0.x to the 2.x.x version you want.
If your APC device is running a 2.0.x of the AOS firmware module
already, you can upgrade directly to version 2.1.0 or a later version.
