Preface PREFACE This manual provides installation instructions for InterReach Spectrum® Remote Access Units (RAUs). Table 1 lists the standard RAUs that are supported in this document. Table 1.
Document Cautions and Notes Document Cautions and Notes Two types of messages, identified below, appear in the text: CAUTION! Caution text indicates operations or steps that could cause personal injury, induce a safety problem in a managed device, destroy or corrupt information, or interrupt or stop services. NOTE: Note text contains information about special circumstances.
Product Overview PRODUCT OVERVIEW InterReach Spectrum supports up to 8 bands in a single system. Each antenna location supports those bands in modular, group pairings. Each location includes a Main Remote Access Unit (MRAU) that can power up to three additional Secondary RAUs (SRAUs), each of which support two power amplifier pairs for a total of eight amplifiers.
Standards Certification Figure 1 illustrates how RF and IF signals are sent between Spectrum units and modules. NOTE: All FWD ports on all Modules are color‐coded red and all REV ports are color‐coded blue, which makes the DRU, IFEU, and RAU cabling process easier to complete.
Product Overview Main Remote Access Units The Main Remote Access Unit (MRAU) receives FWD IF signals from an IF Expansion Unit (IFEU), which is part of the Spectrum Expansion Module Group, using 75 CATV cable. The MRAU converts the IF signals to RF and sends them to a passive RF antenna using 50 coaxial cable. The MRAU also receives configuration information and power from and sends its status information to the IFEU. The MRAU receives REV RF signals from a passive RF antenna using 50 coaxial cable.

Product Overview Secondary Remote Access Units A Secondary Remote Access Unit (SRAU) receives FWD IF signals from the MRAU, using 75 CATV cable. The SRAU converts the IF signals to RF and sends them to a passive RF antenna using 50 coaxial cable. The SRAU, through the MRAU, also receives configuration information and power from and sends its status information to the IFEU. The SRAU receives REV RF signals from a passive RF antenna using 50 coaxial cable.

Product Overview RAU N Connectors Each RAU also has one or two 50‐ N‐type connectors that connect to a passive antenna. Table 3 lists the number of N‐type connectors available on each RAU model. Table 3.
Mount the RAUs and Antennas INSTALL THE RAUS AND ANTENNAS Follow the steps in the order provided to install the RAUs and antennas. Mount the RAUs and Antennas CAUTION! Wet conditions increase the potential for receiving an electrical shock when installing or using electrically powered equipment. To prevent electrical shock, never install or use electrical equipment in a wet location or during a lightning storm. CAUTION! This system is a RF Transmitter and continuously emits RF energy.
Install the RAUs and Antennas Do the following, in the order presented, to mount the RAUs and antennas: 1 Mount all MRAU and SRAUs in the locations marked on the floor plans. 2 Install the passive antennas according to the manufacturer’s installation instructions. NOTE: 3 It is common practice to install passive antennas below the ceiling. If you install a passive antenna above the ceiling, when estimating the antenna coverage area, account for additional loss due to the ceiling material.
Connect the IFEU to the MRAU 6 Connect F connector CATV cables on the IFEU and MRAU, in the order given below. If the LEDs do not perform as described in this procedure, refer to “MRAU LEDs” on page 7. a Connect a CATV cable from one of the IFEU FWD Module IF OUT connectors (1 ‐ 8) to the MRAU FWD IF IN connector. b Confirm that the MRAU FWD IF IN LED is yellow, which indicates a correct physical connection.
Install the RAUs and Antennas Connect the MRAU to SRAUs CAUTION! 7 To prevent interference, do not install an 850/1900 MRAU antenna near an 800/900 SRAU. The 850 MHz band must be 20 feet away from the 800/1900 SRAU’s passive antenna. Use one of the following 6’ and 20’ CATV RG6 jumpers, available for purchase from TE Connectivity, to connect an MRAU to SRAUs. TE Connectivity Part Number Description Note 300469-0 6’ RG-6 Cable; F Male to F Male CATV cable that connects the MRAU to SRAUs.
