Replacing a Main Hub
1. Turn off the power to the Main Hub.
2. Disconnect all fiber cables and the AC power cord.
3. Replace the Main Hub with a new one.
4. Connect the AC power cord and all fiber cables – remembering to clean and cor-
rectly connect the uplink and downlink fiber cables.
5. Connect the null modem cable to the PC and then to the Main Hub’s front panel
DB-9 serial connector.
6. Start the AdminManager software.
7. Select the Installation Wizard option from the AdminManager main window.
8. Turn on the power to the Main Hub.
9. Observe the LEDs after turning on the power.
If there is no band programmed in the Main Hub, the LEDs will blink continu-
ously and there is no communication with connected Expansion Hubs or their
RAUs.
If there is a band programmed, the LEDs blink for a 5-second test. The pro-
grammed band is then issued to all Expansion Hubs and their RAUs, and a system
test is performed. It can take up to 1.5 minutes to complete the test. During Sys-
tem Test, the entire system is temporarily off-line and no RF is being trans-
mitted.
AdminManager Tasks

• Set the Operation Band

• Perform System Test
During System Test, the entire system is temporarily off-line and no RF is
being transmitted. For a fully-loaded system (one Main Hub, four Expansion
Hubs, and 32 RAUs), it can take up to 1.5 minutes to complete the test.
Always perform the system test if the band was changed.
