5 Firmware Upgrade and Downgrade Paths
The following sections detail firmware upgrade and downgrade paths for TERA firmware on zero clients
and host cards.
NOTE: See Revision K and lower of this document for information about TERA 1-based zero clients and
host cards.
5.1 For Instructions about Upgrading Devices
You can upgrade the firmware of individual ClearCube zero clients and host cards by uploading self-
installing firmware files through a Web interface or by using ClearCube Sentral. You can also use Sentral
to upgrade groups of devices. See PC-over-IP System User’s Guide for information about updating device
firmware. See Sentral Administrator’s Guide for information about using Sentral to upgrade device
firmware, for information about device groups, and more.
5.2 Upgrading TERA Firmware
The table below shows the firmware upgrade paths for firmware release ranges. See PC-over-IP System
User’s Guide for instructions about how to perform firmware upgrades.

2. Install firmware version 1.x (1.4 or greater).

5.3 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: Always use the same TERA version on the host and client.
