Description

Highlights of this update

xNode version 2.4.22 provides additional metering in the web interface. Now, metering is available for the Livewire In/Out and the physical In/Out. Additionally, we have made security improvements as a result of user feedback. See below for detailed release notes.

Preparation for Update

Starting with Version 2.0, we added significant upgrades for the Telos Alliance xNode product line. It includes a fully configurable mixing matrix, user interface improvements, and full AES67 compatibility. If you are updating from a version OLDER than 2.0, please familiarize yourself with these features and their operation. It’s essential to understand the release notes, as some of your settings may be affected by this update.

An Axia xNode has two internal memory “banks.” Each bank contains room for a complete version of operating software. This approach allows a software update download to be completed and checked without the danger of making the unit inoperable if the download were incomplete or corrupted. It also provides an easy way to try a new software version and still return to the old version.

The software version in each bank is displayed on the System web page. The lower half of this screen, pictured below, shows the firmware versions present and allows you to select what bank will be used at startup. To change banks, click the radio button for the desired bank and then click on Apply.

IMPORTANT! The xNode will reboot after you click ‘Apply’ if you change the software version. This reboot will result in loss of audio locally, and at any unit using the local sources.

Upload new software as follows.

Read the information, download the file, and then come back to this document.

Open a web browser and connect to the xNode to be updated.
Select the System link from the left side menu.
From the System page, select the Choose File button to locate the file downloaded from the previous document.
Once the proper file is selected, the path and filename will be displayed in the text field associated with Bank 1.
Click on Apply to upload the file.
A successful upload will be indicated by the new version being displayed in the Bank 1 field
When you are ready, click the radio button for Bank 1 and click Apply to reboot and make Bank 1 active.

What do you do if you do not have the "Choose File" button?

Sometimes, the device may already have software in Bank 0 and Bank 1. If the xNode has Bank 1 currently selected, a Browse button will not allow you to choose a file for upload. In such cases, you will need to select the box “commit this version to Bank 0” and press the Apply button. Doing so will move the software to Bank 0 and clear Bank 1 so that a new version can be uploaded. Committing from Bank 1 to Bank 0 does not require a reboot.
