Fusion Installation Procedures

7-36 InterReach Fusion Installation, Operation, and Reference Manual

CONFIDENTIAL D-620610-0-20 Rev B

7.4.3.2 Installing RAUs in a Multiple Operator System

When installing both iDEN and Cellular systems in parallel, either as dual-band or

multiple operator systems, you must take special provision to assure that the individ-

ual RAUs do not interfere with each other.

The 850/1900 MHz and 800/900/1900 MHz RAU’s antennas must be separated

by at least 8 meters (26 feet) to assure that the iDEN downlink signals do not

interfere with the Cellular uplink signals.

7.4.4 Configuring the System

Before the system can operate properly, use AdminBrowser to program the Fusion

Main Hub with the frequency bands that are to be distributed. The Hub must be pro-

grammed with the same frequencies as the RAU used.

NOTE: The frequency bands should automatically be set on power up and

this step should not be required.

Considerations:

• The AdminBrowser software, described in the AdminBrowser User Manual

(PN D-620607-0-20), must be running on a PC/laptop.

• Crossover Ethernet cable with male connectors required.

Connecting the PC to the Fusion Main Hub to Run AdminBrowser

1. Connect the AC power cord to the Hub.

Make sure the Hub is grounded through the ground lug on the AC power

and the frame ground lug as required. The warranty does not cover damage

caused when an ungrounded Hub is powered on.

2. Plug the power cord into an AC power outlet.

3. Verify that all cables are properly connected on the Hub.

4. Turn on the power to the Hub.

All LEDs blink through the power up sequence. At each port where an RAU is

detected (drawing current), the port LEDs lights green. The Fusion

STATUS LED

is orange during system boot and should turn green after about 90 seconds if it

finds no faults. This state indicates the band’s are not programmed and provides

feedback on the status of the RAU connections.

The LEDs blink for 20 seconds as a visual check that they are functioning.

5. Connect the cross-over Ethernet cable to the PC/laptop and then to the RJ-45

100-BASE-T

port on the Hub’s front panel.
