1) Login to your controller (AJRB-Managed Controller: https://omada.ajrb.co.uk:8043)
2) Click the settings cog on the bottom-left
3) Go to 'Services' > 'SSH' and enable SSH, then enable Layer 3 accessibility if you're accessing from a different subnet
4) Go to 'Site' then get the device credentials
5) Copy the password. You will need this to SSH.
6) Open Command Prompt on Windows, or Terminal on MacOS. This only works on Windows 10 and above, unless you are using PuTTY
Type command:
ssh admin@IPADDRESS
IPADDRESS = the IP address of your device that you want to manage
example: ssh admin@192.168.0.1
This should now work for you. Please only use SSH to connect to your devices if you know what you are doing! This is for advanced users only. Consult AJRB Services before making any drastic changes.
