[Description] Select this check box to enable establishing connection to the Perforce server. If there is a connection but the server does not respond (for example, because the server is backing up currently), you can disable such attempts by clearing this check box, or RubyMine will suggest to do that after a timeout. After that the version control-specific operations will be disabled. [Item] 
Perforce is online
