You can start IP Office Manager using Web Manager. When a Server Edition Secondary server is present, you cannot launch Manager using Web Manager from the Server Edition Secondary server, unless the Server Edition Primary server is down.
You can start Manager without using Web Manager if you installed Manager on your computer. To install Manager, use the IP Office Admin DVD or AppCenter page of the Server Edition Primary server. For more information, see Administering Avaya IP Office™ Platform with Manager.
Note:
When you start Manager using Web Manager for the Server Edition Secondary server, you can manage only the systems that are online. After the Server Edition Primary server is up, you must synchronize the offline and online configurations.
