Hi Ameen,
You can certainly do it thru CM and CLI.
From CM, click on My WAN --> Manage Devices --> Edit device (where you see the small computer icon in column 1).
Once you are on Dashboard of that device, you will see RELOAD button somewhere in the middle of the page. I am attaching picture for your reference.
From CLI, login using telnet / ssh (whichever is enabled in your network environment).
once you login, just apply "reload" from CLI and it will reload the box.
Hope this helps.
Regards.
