The BootWare program is upgraded together with the Comware application. When you upgrade
the Comware application program, the system automatically checks whether the current BootWare
version is compliant with that included the updated Comware application and upgrades the current
BootWare if needed.

Before upgrading the software of your access controller, check the current BootWare version and
Comware application version to make sure that the correct file is used for the upgrade. For the
association between the Comware application version and the BootWare version, refer to the
version compatibility matrix in Release Notes.
Modifying Serial Interface Parameters
Sometimes, we need a high serial interface baud rate to save the update time, or a low baud rate to
ensure transmission reliability. This section introduces how to adjust the serial interface baud rate.
Enter the BootWare main menu and enter 2 to go to the serial submenu, and then enter 5 on the
submenu to modify the baud rate. The system displays the following:
==============================================================
|Note:'*'indicates the current baudrate |
| Change The HyperTerminal's Baudrate Accordingly |
|---------------------------------------------------- |
|<1> 9600(Default)* |
|<2> 19200 |
|<3> 38400 |
|<4> 57600 |
|<5> 115200 |
|<0> Exit |
============================================================================
Enter your choice(0-5):
Select a proper baud rate. For example, enter 5 for a baud rate of 115200 bps and the system displays
the following information:
Baudrate has been changed to 115200 bps.
Please change the terminal's baudrate to 115200 bps, press ENTER when ready.
At this time, the serial interface baud rate of the access controller is modified to 115200 bps, while that
of the terminal is still 9600 bps. The access controller and the terminal cannot communicate with each
other. Change the baud rate to 115200 bps on the terminal.
Perform the following operations on the terminal:
