Security settings within Internet Explorer can stop navigation within PCNS or block communications all together.
To solve this navigation issue, you can put the server IP in as a trusted site in Internet Explorer. To do this, open Internet Explorer and go to the Tools/Internet Options menu. Select the Security tab and the Trusted Sites icon. Click the Sites button and there will be an edit field where you can enter the Full Qualified Domain Name of the system running PowerChute.
Once entered, click the add button and then click the OK button. Click the OK button for internet options and you should now be able to navigate the PowerChute menus. If this does not work right away, please try closing and reopening the browser and navigate back to the PowerChute Network Shutdown page.
