SECTION 7 Replacing Unison Accel
Components in an Operational
System
7.1 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 Accel Hub automatically checks the band of a replaced RAU. There is no need to
issue commands directly from the Hub. Therefore, as long as the RAU is of the cor-
rect band, the system will operate properly.
Replacing an RAU
1. Use AdminManager or refer to the As-Built Document to review the current
RAU’s configuration. To use AdminManager:
a. Select Get Unit Info command from the Configuration and Maintenance
Panel.
The Options dialog box is displayed (see Get Unit Info in the AdminManager
User Manual, PN 8810-10).
b. Select Remote Access Unit radio button.
c. Enter the hierarchy of the RAU in the text box.
For example, for RAU number 4 that is connected to Expan-
sion Hub number 1, enter 1-4.
d. Click OK.
Information for the RAU is displayed in the Configuration and Maintenance
Panel window.
5. Disconnect the Cat-5/6 cable and antenna from the unit to be replaced.
6. Install the new RAU.
7. Connect the antenna and then the Cat-5/6 cable to the new RAU.
8. Repeat Step 1 to verify that the new RAU is of the same frequency band as the
one replaced.
