Logging in to Command Central

Open an Internet browser and specify the URL of the Command Central Server as follows: http://<Command_Central_host>:<Command_Central_port>. This takes you to the Command Central Login page.

On Windows you can also get to the Login page from the Command Central Start Menu entry.
