4-2 LGCell Installation
System Requirements An LGCell system has location, space, power, and safety requirements for installation. The Dual Band LGCell requirements for space and power are different from those for a single-band system and are noted below. System Location The LGCell Main Hub and Expansion Hub mount into a standard 19" equipment rack in a wiring, telecom, or electrical closet, which may contain other Ethernet, telephony, or miscellaneous equipment.
Underwriters Laboratory Installation Guidelines Use the following guidelines when rack mounting the LGC Cell: 1 Do not exceed the maximum ambient air temperature of 45° C during operation. Provide sufficient airflow and cooling within the rack to prevent heat build-up from exceeding this limit. 2 Be careful when servicing these products. If you are removing the system from the rack, turn it off and remove the power cord first. There are no user serviceable parts inside the hubs or RAUs.
• Live work: Live work is permitted on the LGCell as it is a Class 1 hazard. • Signs: No warning signs are required. • Test equipment: Use Class 1 test equipment. Cable and Connector Requirements The LGCell equipment operates over standard TIA/EIA 568-A specification, Category 5 (CAT 5), or better, Unshielded Twisted Pair (UTP) or Shielded Twisted Pair (STP) and standard 62.5µm/125µm Multi-Mode Fiber cable (MMF), at a wavelength of 1300 nanometers (nm).
LGCell system installation includes the following tasks: • Installing Main Hub • Installing Expansion Hubs • Installing Remote Antenna Units (RAUs) and antennas • Connecting RF cables • Connecting CAT 5 cables • Connecting MMF cables • Optimizing the system These procedures tell you how the LGCell should respond during various phases of the installation. If it is not responding as it should, see Section 6, Common Problems, Troubleshooting, and Frequently Asked Questions.
This diagram illustrates how the LGCell is configured. The rest of this section contains configuration and installation procedures. Main Hub Installation Your installation may have one or more Main Hubs, each located in the same or different wiring closet. Use the following procedures for all Main Hubs.
2 Connect Power and Power Up After mounting the Main Hub, connect the AC power cord to the Main Hub. Plug the power cord into an outlet providing AC power (88-264 VAC). See 1 in graphic. Power up the Main Hub by flipping the power switch from position 0 to position 1. See 2 in graphic. The POWER and SYNC LEDs on the front panel should be green (lit).
The connections for the Dual Band system are shown here. Make sure you connect the 900 MHz Main Hub to the 900 MHz Expansion Hub and the 1800 MHz hubs together. Be sure the MMF cable ST-connectors are clean and free of dust or oils. If the fiber connector front face is not free of dust or oils, follow the manufacturer’s recommendations for cleaning it. The MMF cable is labeled with either 1 or 2, or is color-coded.
Be sure to record which number or color is connected to UP and to DOWN. This information is needed when connecting the other end of the MMF cables to the Expansion Hub ports. 4 Check Main Hub LEDs The POWER and SYNC LEDs should be green. If not, reset the Main Hub. If the POWER and SYNC LEDs do not light green, see Section 6, Common Problems, Troubleshooting, and Frequently Asked Questions. The LINK STATUS and SYNC LEDs on the ports where the fiber is connected should be red.
1 Mount the Expansion Hubs Mount 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 Up Connect the AC power cord to the Expansion Hub.
3 Connect the MMF cables Connect 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 LEDs Connect 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.

International customers, please contact us at +1-408-487-2400.
6-2 Common Problems, Troubleshooting, and Frequently Asked Questions
Common Problems and Troubleshooting The LGCell has three sources of potential problems: • Malfunction of one or more LGCell component • Faulty cabling/connector • Antenna, base station, or repeater problem By far, most problems discovered have to do with faulty cabling. All CAT 5 cable should be tested to TIA/EIA 568-A specifications. The diagnostic procedures are based on information in the Diagnostic Table on page 9. The table lists all LEDs and indicates what to do under certain circumstances.
LED Indicator Description The LGCell Main Hub, Expansion Hubs, and RAUs have front panel LEDs. The LEDs provide diagnostic information and operational status of each unit. Together they provide an efficient diagnostic display system, which help technicians find the fault if there is a malfunction. Main Hub LEDs There are two sets of LEDs on the Main Hub front panel: •Main Hub MMF Ports •Main Hub Functionality LEDs • Main Hub MMF Ports LEDs Provides status on each of the Main Hub’s four MMF ports.
Expansion Hub LEDs There are two sets of LEDs on the front panel • Expansion Hub UTP/STP Ports • Expansion Hub Functionality • UTP/STP Ports LEDs Provides status on each of the Expansion Hub’s four UTP/STP ports. LED LINK STATUS SYNC • Color Indication Green Indicates good connection to the RAU. Red Connection problem between Expansion Hub and the RAU plugged into that port. Green Indicates RAU connected to it is operating properly. Red Problem with the RAU plugged into that port.
RAU LEDs RAUs have two LEDs: •Sync •Power LED Color Indication SYNC Red Antenna lost sync and has shut down RF power. POWER Green Antenna is plugged in and the connected Expansion Hub is on. Troubleshooting Guidelines The LGCell Main Hub, Expansion Hub, and RAUs have front-panel indicator LEDs that provide diagnostic information and the operational status of each unit. Together they provide an efficient diagnostic display system for maintenance and fault location if a malfunction ever exists.
Problem/Symptoms Check No downlink signal output when all diagnostic LEDs are green. Make sure that there is a reasonable amount of power at the input of the Main Hub. Measure the output power of the coaxial cable using a power meter. The LGCell is intended for a different frequency band. Verify that your system corresponds to the desired frequency spectrum (for example, 800 MHz, 1800 MHz, or 1900 MHz). Check the part number of each unit. The LGCell is factory set for different bands of operation.
Diagnostic Procedures Use the following table when diagnosing system problems. While troubleshooting, you can copy the blank table on page 12 and use it to record the LED colors on the Main Hub, the particular Expansion Hub indicating a fault, and the RAUs connected to it. This is necessary because the Main Hub, Expansion Hubs and RAUs might be geographically distributed. To determine where the fault might be 1 2 6-8 Go to the Main Hub and record the LEDs.

4 Power is not being delivered to the RAU. • Switch the UTP cable to a different Expansion Hub port to see if the same problem occurs. If the LEDs on the new port are both green, there is a problem with the Expansion Hub. If the problem persists, there is a problem with either the RAU or the UTP/ STP cable. • Check that the UTP/STP cable has been properly crimped and passes a standard TIA/EIA 568-A CAT 5 compliance test. If the cable passes the CAT 5 test, replace the RAU.
• If the problem persists, replace the Main Hub. • If the problem persists, replace the Expansion Hub. 8 The Main Hub is off. Make sure the power cord is connected to a live AC power jack and that the Main Hub power switch is in the 1 position. 9 Main Hub is not properly generating the synchronization signal. Turn off the Main Hub and turn it back on. If the sync LED stays off, the Main Hub might require replacement.

Frequently Asked Questions The following list provides answers to some frequently asked questions about LGCell: 1 What is the LGCell Distributed Antenna System? The LGCell Distributed Antenna System (DAS) contains multiple low-power radiating elements that are deployed around indoor facilities to improve coverage and capacity.
6 Can the LGCell system share the same UTP Category 5 Cable with the Ethernet network? No. The LGCell system can use the existing unused cabling inside the building; however, you cannot use the same cable to connect an RAU and a computer. 7 What is the minimum power input to the Main Hub? The coverage area of an RAU is directly related to the input down link power at the Main Hub. Therefore, an input power that generates an output power of 0dBm per channel optimizes the coverage area of an RAU.
