To configure BlackBerry® Router high availability, you can create a BlackBerry Router pool for each BlackBerry® Enterprise Server by assigning multiple BlackBerry Router instances to the BlackBerry Enterprise Server. The BlackBerry Enterprise Server determines which BlackBerry Router instance to connect to by trying to connect to the first BlackBerry Router instance in the pool list. If the BlackBerry Enterprise Server cannot connect to the first BlackBerry Router instance in the list, it tries to connect to each BlackBerry Router in sequence until a connection succeeds.

For more information, see the BlackBerry Enterprise Server Planning Guide.

1. In the BlackBerry Administration Service, on the Servers and components menu, click BlackBerry Solution topology > BlackBerry Domain > Component view > BlackBerry Enterprise Server.
2. Click the name of the BlackBerry Enterprise Server or the name of the BlackBerry Enterprise Server pair that you want to assign the BlackBerry Router pool to.
3. Click Edit instance.
4. In the SRP Address section, type the FQDN of the computer that hosts the BlackBerry Router instance.
5. If the BlackBerry Router instance uses a port number other than port number 3101, in the Port override field, type the port number.
6. Click the Add icon.
7. Repeat steps 4 to 6 for each instance that you want to add to the pool.
8. Click Save all.
9. Restart the BlackBerry Enterprise Server using one of the following methods:
   • If you are changing a BlackBerry Enterprise Server instance, on the Instance tab, click Restart instance.
   • If you are changing a BlackBerry Enterprise Server pair, click on one of the instances. On the Instance tab, click Restart instance. Repeat this step for the other instance.
   • In the Windows® Services, restart the BlackBerry Dispatcher.
10. Repeat steps 2 to 9 for each BlackBerry Enterprise Server instance in your organization's environment that you want to have use a BlackBerry Router pool.

If you installed a BlackBerry® Router on a computer that is separate from the computer that hosts a BlackBerry® Enterprise Server, you must permit the BlackBerry Dispatcher that you installed with the BlackBerry Enterprise Server to connect to the BlackBerry Router. The BlackBerry Router that you installed on a separate computer can send data packets from the BlackBerry Enterprise Server to BlackBerry devices.

1. On the computer that hosts the BlackBerry Router, click Start > Run.
2. Type regedit.
3. Click OK.
4. Perform one of the following actions:
   • If you are running a 32-bit version of Windows®, navigate to \\HKEY_LOCAL_MACHINE\SOFTWARE\Research In Motion.
   • If you are running a 64-bit version of Windows, navigate to \\HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node \Research In Motion.
5. Change the value of AllowRemoteServices to 1.
6. If you want to change the port number that the BlackBerry Router uses to open connections to the BlackBerry Dispatcher, change the value of ServicePort to the port number that the BlackBerry Router should use, for example, port number 80. By default, the port number is 3101.
7. In the Windows Services, restart the BlackBerry Router service.
