NBX System Software Upgrade Instructions
1
Before you begin to upgrade your 3Com
®
NBX
®
software, read ALL of these instructions and all of the
Release Notes (the readme.pdf file on the NBX Resource Pack CD). For details on each screen in the
NBX NetSet™ utility, click the Help button on the screen.
!
CAUTION:
To upgrade an NBX system to R5.0 software, you
must
first upgrade to NBX
Release
R4.3
or higher. If you upgrade from R4.2.6 or an earlier release, and then later
reboot to that earlier release, some 3Com telephones become disabled and the error
message "checksum error" appears in the telephone display panel.
If you do not choose to retain your database during the upgrade reboot operation, the configuration
reverts to the default database.
Be aware that Call Data Reporting 5.0 does not work with CDR records at R4.3 or below. See the
information about CDR 5.0 later in this document.
FIRST: BACK UP YOUR DATABASE AND LICENSES
1. Make a note of the version of software that you are currently running. You might need to know this
in a later step of the upgrade process. You can see the version number on the NBX NetSet utility
opening screen or on an NBX Telephone display panel by picking up the handset, pressing the
Feature button, and then dialing 837.
2. Start the NBX NetSet utility: Open Microsoft Internet Explorer, enter your NBX system's IP
address, and then press Enter.
3. Log on to the NBX NetSet utility as administrator. (Be sure to use a lower case “a” when typing
administrator as the username because the NBX operating system is case-sensitive.)
4. Select Operations > Manage Data and click the button labeled Backup Database.
The backup process creates a .tar file that you save in a location of your choosing. For more
information about this process, see the online help for Manage Data.
5. Select Operations > Manage Data and click the button labeled Backup Licenses.
The backup process creates a .tar file that you save in a location of your choosing. For more
information about this process, see the online help for Manage Data..
SECOND: REMOVE OBSOLETE SYSTEM SOFTWARE (NBX 100)
To be sure that there is enough room on the hard disk, 3Com recommends that you retain the current
version and only one or two previous versions of software on an NBX 100 system. To remove an old
version of software:
1. Log on to the NBX NetSet utility as administrator.
2. Select Operations > Software Upgrade.
3. From the "Select version to remove" list, click the software version that you want to remove.
4. Click
Remove.
5. Repeat until you have deleted all of the older versions that you want to remove.
