Firmware Upgrade and Downgrade Paths
Rev K 1.10.04.08.2014 9
4.3 Downgrading TERA Firmware
The previous table shows ranges of TERA firmware versions. Some ranges of firmware require installing
a specific version of firmware before you can upgrade or downgrade to the next range of firmware. You
can use the previous table to determine if your downgrade path requires the installation of an
intermediate firmware version. For information about how to downgrade firmware, see PC-over-IP
System User’s Guide, available on the ClearCube Support site.
NOTE: ClearCube recommends always using the same TERA version on the host and client.
4.4 Upgrading COMM Firmware
The following tables outline upgrade requirements for each firmware version and provide bootloader
(U-Boot) version information to aid in verifying the success of an upgrade. See PC-over-IP System User’s
Guide for instructions about how to perform firmware upgrades.
NOTE: The following table assumes you are upgrading to the latest firmware version.
Installed Firmware Version Upgrade Process
0.4.23 through
0.4.17upd
Install the version to which you are upgrading.
0.4.17 through 0.4.13, and
0.4.11
1. Install the I9400-0.4.17upd-rd-fw.zip or cct8377-
0.4.17upd-rd-fw.zip to the appropriate device as
listed above.
2. View the Version screen to ensure that 0.4.17upd
has loaded correctly. The Tera version will not
change during this step.
3. Install the firmware to which you are upgrading.
0.4.12
1. Install the 0.4.17 (NOT 0.4.17upd).
2. See the Version screen in the device’s Web
interface to ensure the U-Boot version is upgraded
appropriately (to 2010.03-00033).
3. If the U-Boot version does not increment to the
appropriate version number, perform the firmware
installation again. After reinstallation, the U-Boot
version should display correctly (see the following
table for U-Boot version information).
Verifying U-Boot Version When Updating COMM 0.4.12
The following table shows the version of the U-Boot bootloader included with each COMM version.
After upgrading COMM firmware from version 0.4.12, ensure that the U-Boot version displayed in the
Version screen of the device’s Web interface displays the correct version number. See PC-over-IP System
User’s Guide for information about upgrading firmware and about the Web interface.
NOTE: U-Boot is included in each COMM firmware release.
