Chapter 7 Upgrading, Restoring, and Backing Up System Software and Firmware
Upgrading Firmware
The Access Concentrator system selects only the default driver when the I/O
or server module initializes for the first time. When selecting the version of
the firmware you want to download to the module, the drivers displayed
represent the only downloadable versions for the module highlighted under
the
Card Type
field.
During the upgrade of Access Concentrator system software or a firmware
patch, one of three scenarios can occur, according to which driver you
initially select. The three scenarios are described as follows:
•
If you select the default driver on the Firmware Version Control window,
and you upgrade the system software to a version that has both types of
drivers, the system will upgrade the driver to the next version of the
default driver, because that is the type of driver you initially chose.
•
If you select the nondefault driver on the Firmware Version Control
window, and you upgrade the system software to a version that has both
types of drivers, the system will upgrade the driver to the next version of
the nondefault driver, because that is the type of driver you initially
chose.
•
If you select either type of driver on the Firmware Version Control
window, and you upgrade the system software to a version that has only
one type of driver, the system will upgrade the driver to the one available
driver, even if you did not originally select that type of driver before the
upgrade.
To download firmware to the I/O and server modules, perform the steps in
the following procedure, beginning at the Console Interface Main Menu
window (see Figure 7-8).
