332 CHAPTER 7: OPERATIONS
When the software upgrade is complete, a new window, containing a
confirmation message, appears in NBX NetSet.
At certain times during an upgrade, the system reboots itself. Do not
interrupt the reboot; wait until the upgrade is complete.
Before you upgrade your system software, 3Com recommends that
you back up your system data. (See Backup on page 336.)
If you are using NBX PC applications, such as pcXset, you must also
upgrade these applications after upgrading the NBX software.
If you are connected to the NCP COM1 port, you see the upgrade
activity messages during the upgrade process, but you cannot issue
any commands.
After you upgrade your system software, you must reboot the system.
To upgrade or remove software, select Operations > Software Upgrade.
See the Help for procedures on upgrading or removing software.
System Software
Licensing
To run release R4.2 and all later releases of the NBX system software on
your NBX system, you must have and install a license. A license key is
required only for upgrading to major releases, RX.X. All minor releases,
RX.X.X, use the corresponding major release license key. All NBX systems
that ship from the factory with software release R4.2 or any later release,
include a license for the software version that is shipped with the system.
Upgrading to R4.2 From a Previous Release
To upgrade an NBX system to release R4.2 you must first upgrade to
release R4.1.
Upgrading From R4.1.14 and Prior Releases
If your NBX system software is release R4.1.14 or a previous release, you
cannot enter the license key for R4.2 before you upgrade because the
NBX system software will not recognize the R4.2 license as valid.
Use these steps to upgrade to R4.2:
1Upgrade to R4.2 in the usual way.
2Reboot to R4.2.
3When you see the warning message that indicates you must install a
license, click the License button and install the R4.2 license.
