Firmware upgrade components
To upgrade the firmware on the Avaya 7406E Digital Mobile Handsets and on the base station, or
base stations, you need the following components and materials:
• USB-to-UART bridge controller
• Handset adapter
• Upgrade cables
• Upgrade CD
USB-to-UART bridge controller
The USB-to-UART bridge controller is a firmware upgrade component. Use this hardware to
transfer the new firmware upgrade from your PC to your Avaya 7406E Digital Mobile Handset
system. You connect the bridge controller to your PC using a USB-to-UART cable (see figures
Figure 9 on page 34 and Figure 11 on page 36 ). The bridge controller has a UART port. You
connect the bridge controller to the upgrade jig, or directly to the base station in the case of a base
station upgrade, using an upgrade cable. The bridge controller is powered using the provided AC
power source (see
Figure on page 34 ). Refer to Chapter 6, “Upgrading the firmware,” on page 49
for details on how to upgrade the firmware on your Avaya 7406E Digital Mobile Handset and
Avaya 7406E Digital Mobile Handset base station.
