There are several firmware upgrade files available for Tesira firmware upgrades. This article describes how to determine which file you need, and links to specific firmware upgrade instructions for each case.
Which firmware file should I use?
There are two types of firmware files available:
- One-time upgrade to v2.1.0
- Normal firmware update
The one-time upgrade file can only be used to upgrade a Tesira device from firmware version 1.x to version 2.1.0. If you're trying to upgrade a device from 1.x to a version that is newer than 2.1.0, you'll need to apply the one-time upgrade first, and then apply the normal firmware update. For detailed instructions on applying the one-time upgrade, see Upgrading Tesira firmware to version 2.x.
Normal firmware update
If your Tesira device already has a 2.x firmware version loaded on it, then the normal firmware update file should be used. This file can only be used if the Tesira device's current firmware version is 2.0.0 or later. See Normal Tesira firmware update procedure for more information.
