Summary:

This document explains the requirement and configuration required to upgrade cnMatrix Switches to the latest software version through the TFTP server.

Cause:

This document explains how to upgrade cnMatrix Switch through the TFTP server.

Solution:

Upgrade through CLI:

Step 1: Download the latest software file (cnMatrix-EX2K-2.1.2-r1.img/tar.gz) from the cambium support site (https://support.cambiumnetworks.com/files/cnmatrix/).

Note: If the cnMatrix switch current version is older than 2.1-r5 then you need to download .img file for the upgrade. If the switch is running on 2.1-r5 and wants to upgrade to the latest software version then you need to use tar.gz file extension.

Disable windows firewall and antivirus settings on the laptop/desktop during this process because sometimes it interrupts the communication between switch and TFTP server.

Step 2: Setup TFTP server on PC and check network connectivity between switch and PC using ping:

## In my example I have used the Tftpd64 application for TFTP server.

 

You need to select a PC interface that communicates to the network/management IP of cnMatrix along with the directory where you have stored the software file.

Step 3: SSH the switch using management/network IP followed by admin credentials and run below command:

Download agent tftp://<PC interface IP>/<complete software filename>

Step 4: After the successful download, Reboot the Switch to load the new image.

Step 5: After the successful reboot, please check the software version by using the command “show system information” on the switch.

Upgrade through GUI:

Follow Step 1 and Step 2:

Step 3: Log into the web GUI of the cnMatrix switch using the network/management IP address and enter the Username and Password.

Note: Default IP on the Switch Management port is 192.168.0.1 and by default, only HTTPs access is enabled for web access.

Step 4:  Click on System >>> Software Upgrade select the Upgrade from as TFTP, enter Server IP Address (which is laptop interface IP address) and File Name as shown in the figure below:

## After the necessary settings, click the Apply button.
