SSH

Use a SSH client (e.g. PuTTY, FireFTP, etc)

Give it the device IP address, select SSH, port 22.

These are the default user account details:

Username: Administrator

Password: p@ssw0rd (this will likely may have been changed by you when ssetting up the device)

If it won't connect try re-booting the device (we had to after it had done an update to get SSH to work)
