Part 5 Users Manual

4-111 Mount the Expansion HubsMount the Expansion Hubs onto the rack in the assigned wiring closet location, using four screws per hub.For air circulation, be sure to leave at least one inch (25 mm) space between all hubs and between any other equipment in the rack. If mounting a hub on the rack’s bottom shelf, also leave at least one inch (25 mm) clearance from the bottom.2 Connect Power and Power UpConnect the AC power cord to the Expansion Hub. Plug the power cord into an outlet providing AC power (88-264 VAC). See 1 in graphic.Power up the Expansion Hubs by flipping the power switch from position 0 to position 1. See 2 in graphic. The POWER LED on the Expansion hub should be green (lit).
4-12 LGCell Installation3 Connect the MMF cablesConnect all MMF cables from the Main Hub to the Expansion Hubs. The SYNC LED should be green.For proper connection between the Main Hub ports and the Expansion Hub ports, refer to the numbering or color coding you recorded when installing the Main Hub.4 Check Expansion Hub LEDsConnect all MMF cables from the Main Hub to the Expansion Hubs.The LINK STATUS and SYNC LEDs on each Expansion Hub port should be red when the UTP/STP cable is not yet connected to the RAUs.
4-13Remote Antenna Unit (RAU) Installation5 Connect UTP/STP cables from RAUsConnect all UTP/STP cables coming from the RAUs to any available RJ-45 connector on the Expansion Hub.The Expansion Hub fiber port LINK STATUS and SYNC LEDs should be green or off.The LINK STATUS and SYNC LEDs on each Expansion Hub port should remain red until the RAU is connected on the other end.1 Connect AntennasConnect an accessory antenna to each RAU SMA connector. (The illustration shows the RAU with an optional Rubber Duck antenna.)When connecting to the SMA connector on the antenna, DO NOT over-tighten the connector. Firmly hand-tightening the connector is adequate.TENNA PORTSLGCell™ EDOWNMAIN HUB PORTSUPSYNCPOWERAC POWERANTENNA PORTSLGC WIRELESSLGCell™ Expansion HubLINKSTATUSSYNC
4-14 LGCell Installation2 Mount RAUs and AntennasMount all RAUs in their assigned locations, using the enclosed screws. The RAUs can mount above or below the ceiling, or to a wall.For connecting and mounting an accessory directional antenna, refer to the instructions shipped with that antenna.
4-15The Dual Band RAU mounting is shown below.3 Connect UTP/STP CableConnect the UTP/STP cable coming from the Expansion Hub to the RJ-45 connector on the RAU.
4-16 LGCell InstallationRF Cable ConnectionBefore connecting any cables to the Main Hub, be sure the RF power level does not exceed the input rating for the Main Hub. (See “LGCell System Specifications” on page 16 in Section 2, LGCell Equipment.)For coverage applications, LGC Wireless recommends that you insert a lightning arrestor or surge protector between a roof-mounted antenna and the Main Hub. If you use a repeater, insert the lightning arrestor or surge protector between the repeater and roof-mounted antenna.The following illustration shows how to connect the LGCell for coverage applications, with a repeater.For the Dual Band RAU, connect the 900 MHz Expansion Hub cable to the top connector and the 1800 MHz cable to the bottom connector.4 Check LEDsThe green POWER LED should be on and the red ALARM LED should be off.The green LED indicates that the RAU is receiving power from the Expansion Hub assigned to it.
4-17Duplex ConnectorThis N-type female connector is typically used to connect the LGCell to a repeater, roof-mounted antenna, or MBS, as shown on the previous page.Connect an N-type male RF coaxial cable to the duplex N-type female connector (labeled DUPLEX) on the Main Hub back panel. If an N-type male connectorized RF cable is not available, use an RF adaptor. Connect the other end of the coaxial cable to the roof-mounted antenna, MBS, or repeater.a0721234DOWNLINKSTATUSSYNCUPSYNCPOWERAC POWERTO EXPANSION HUB PORTSLGC WIRELESSLGCell™ Main HubDOWNLINKSTATUSSYNCUPDOWNLINKSTATUSSYNCUPDOWNLINKSTATUSSYNCUPUplink (Reverse) and Downlink (Forward) -MainHubN-Male to N-Male Coaxial CablesN-Male to N-Male Coaxial CablesRoof-Mounted AntennaSurge SuppressorRepeaterTo Ground ConnectorDuplexOutput
4-18 LGCell InstallationThe duplex ports have a variable gain. Please see the table for system gain under “Maximum Input RF Power per Carrier vs. Number of Carriers” on page 17 in Section 2, LGCell Equipment.Downlink (Forward) and Uplink (Reverse) ConnectorsConnect an N-type male RF coaxial cable to the downlink N-type female connector (labeled FORWARD) and an N-type male RF coaxial cable to the uplink N-type female connector (labeled REVERSE) on the Main Hub back panel.Connect the other ends of the coaxial cable to the MBS. For diagrams of connecting LGCell to specific MBS equipment, see Section 5, Connectivity.For simplex MBSs, be sure the MBS downlink coaxial cable connector plugs into the downlink connector, and the uplink coaxial cable connector plugs into the uplink connector on the Main Hub.Alarm Report MonitorA separately orderable option for use with LGCell, the Alarm Report Monitor is an alarm monitoring, reporting, and remote control system. Up to 255 remote-ARM monitoring units can monitor up to 2,040 LGCell systems. Each remote-ARM unit communicates with the ARM software through a dial-up modem connection, using an external or internal modem. A database of these devices is set up in a PC, with a unique address for each device.The ARM supports multiple users and tracks responsibility through log-in and log-out procedures, using four security levels to protect critical system functions. It features a graphic color status display, remote system reset control, alarm history and control logs, security code management, and journal printer and paging options.For ARM installation instructions, see Appendix E – Alarm Report Monitor (ARM2000).a060DUPLEXFORWARDREVERSE
