Remove both mounting brackets from the mounting shelf (requires Phillips screwdriver) and save screws for reuse. 3. Locate the extra mounting brackets that are provided with the mounting shelf and select the brackets that correspond to the rack type. Each mounting shelf includes extra brackets for installing the mounting shelf in the rack types specified in step 1. 4.

ADCP-75-150 • Preliminary Issue A • March 2003 • Section 3: Host Unit Installation possibly damage the HU receiver. Refer to Section 4, Subsection 2.3, before completing the forward path connection between the BTU and HU. If the Conditioning Panel or Duplexing Panel is required, refer to the Digivance 800 and 1900 MHz Interface Panels User Manual (ADCP-75-147) for the installation procedures. The HU should be mounted as close as possible to the BTS to minimize cable losses.

ADCP-75-150 • Preliminary Issue A • March 2003 • Section 3: Host Unit Installation 7 OPTICAL CONNECTIONS The optical interface between the HU and the RU is supported by two optical ports. Each optical port consists of an SC optical adapter which is mounted on the HU front panel. Port 1 provides the optical fiber connection for the forward path (downlink) signal. Port 2 provides the optical fiber connection for the reverse path (uplink) signal.

One of the jacks is designated as the NET IN port and the other jack is designated as the NET OUT port. The CAN interface allows up to 24 HU’s to be connected together (in daisy-chain fashion) and controlled through a single Digivance EMS computer.
