SECTION 8 Replacing Unison Components
8.1 Replacing an RAU
Be aware that the new RAU must be the same band as the one you are replacing. If
you replace an RAU with one that is of the wrong band, it will not work.
The Main Hub automatically checks the band of a replaced RAU. There is no need to
issue commands directly from the Main Hub. Therefore, as long as the RAU is of the
correct band, the system will operate properly.
Replacing an RAU
1. Using AdminManager, right-click on the RAU’s icon and select Advanced RAU
Settings from the Unit Commands menu item.
The Advanced RAU Settings window is displayed. Write down the settings so
you can set the new RAU with the same settings.
2. Click CANCEL to close the window.
3. Verify that the new RAU is of the same frequency band as the one replaced.
4. Disconnect the Cat-5/5E/6 cable and antenna cable from the unit to be replaced.
5. Install the new RAU.
6. Connect the antenna cable and then the Cat-5/5E/6 cable to the new RAU.
7. Right-click on the RAU icon and select Advanced RAU Settings from the Unit
Commands menu item.
The Advanced RAU Settings window is displayed.
8. Set the DL/UL attenuation as the old RAU was programmed and click OK.
