Cisco WLC Software Upgrade via CLI

I had to upgrade a Cisco WLC 2504 from 8.2.166 to 8.2.170 but for some reason, my web browser (both IE and FF) doesn't prompt to reboot the WLC. So I performed a WLC software upgrade using the CLI instead.

Here's a link where I previously performed an upgrade on using the web GUI.
