4-3System RequirementsAn 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 LocationThe 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.•Standard wiring closet temperatures: 0-45° C•Does not require special air conditioningSpace RequirementsThe LGCell Main Hub and Expansion Hubs are installed into a standard 19” rack.•The Main Hub height is 1.7” (44.5 mm). The Dual Band Main Hub is 3.5” (88.9 mm) high.•The Expansion Hub height is 1.7” (44.5 mm). The Dual Band Expansion Hub is 3.5” (88.9 mm) high.•Allow at least one inch (25 mm) clearance between each hub, between any existing equipment in the rack, and between the bottom shelf of the rack and the hub.Power RequirementsThe LGCell requires AC voltage/current. LGC Wireless recommends connecting it to a UPS (Uninterruptable Power Supply), which may exist in the wiring closet. Dual-Band equipment requires twice as much power as single-band equipment.•LGCell operates with 88-264 VAC 50/60 Hz.•The Main Hub uses a maximum of 1.6 A of electrical current.•The Expansion Hub uses a maximum of 1.6 A of electrical current.•The RAUs are powered from the Expansion Hubs via the UTP/STP cable and they use 12V DC.
4-4 LGCell InstallationUnderwriters Laboratory Installation GuidelinesUse the following guidelines when rack mounting the LGC Cell:1Do 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.2Be 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.3Do not compromise the amount of airflow required for safe operation of the equipment when installing it in a rack. Both the Main Hub and the Expansion Hub draw in air on the left side and exhaust heated air at the rear. The hubs pass approximately 6 cu. ft. of air per minute through themselves and only dissipate a maximum of 25 watts of heat from their internal circuitry.4The AC input current consumption of the hubs is rated at 1.6 A at 110 VAC. The internal power supply has internal fuses that are not user replaceable. Consider the worst-case power consumption shown on the product labels when provisioning the rack’s AC power source and distribution.Fiber Port Safety PrecautionsSuggested safety precautions for working with LGCell Fiber Ports follow. For information about LGCell compliance with safety standards, see Appendix C – Compliance Information.•Viewing fiber: Observe the following warning about viewing fiber ends and ports.Do not stare with unprotected eyes at the connector ends of the fibers or the ports of the hubs. Invisible infrared radiation is present at the front panel of the Main Hub and Expansion Hub. Do not remove the Fiber Port dust cover unless the port is in use. Do not stare directly into a Fiber Port.•Test fiber cables: When you use test fiber optical cables, connect the optical power source last and disconnect it first.•Fiber ends: Cover any unconnected fiber ends with an approved cap. Do not use tape.•Broken fiber cables: Do not stare with unprotected eyes at any broken ends of the fibers. Report any broken fiber cables and have them replaced.•Cleaning: Use only approved methods for cleaning optical fiber connectors.•Modifications: Do not make any unauthorized modifications to this fiber optical system or associated equipment.
4-5•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 RequirementsThe 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). These cables are widely used industry standards for Local Area Networks (LANs). The regulations, guidelines, and standards for cable installation are identical to those specified by the TIA/EIA 568-A standard for LANs. See Appendix B – TIA/EIA 568-A Cabling Standard.LGC Wireless recommends Plenum rated CAT 5 UTP/STP and MMF cable and connectors for conformity to building codes and standards.LGCell Standard Equipment•LGCell Main Hub•LGCell Expansion Hub•Remote Antenna Units (RAUs) with an in-building antenna•Four screws for mounting the RAUs•Four rack mount screws per hub to mount hubs into a 19" rack•Installation and Reference GuideLGCell Equipment InstallationThe following are procedures for installing an LGCell system. Pre-testing the system is not required. The installation procedures are based on the following assumptions:•The LGCell equipment has been unpacked and inspected.•Locations for the Main Hub, Expansion Hubs, and RAUs have been identified.•19" rack space is available in the wiring closets.•AC power is available for the LGCell.•MMF and UTP/STP have been pulled into place (based on previous design) and terminated.

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).3 Connect the MMF cablesUsing the procedure below, connect all MMF cables (two per port) to the MMF ST-female connectors (labeled DOWN and UP) on the Main Hub front panel. Use any available Main Hub port.
4-9Be 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. This distinguishes the connectors for proper connection between the Main Hub and Expansion Hubs.If the fiber jumper is labeled with 1 or 2:•Connect 1 to UP on Main Hub•Connect 1 to UP on Expansion Hub•Connect 2 to DOWN on Main Hub•Connect 2 to DOWN on Expansion HubIf the fiber jumper is color-coded (for example, “blue” or “red”):•Connect “blue” to UP on Main Hub•Connect “blue” to UP on Expansion Hub•Connect “red” to DOWN on Main Hub•Connect “red” to DOWN on Expansion HubThe 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.
4-10 LGCell InstallationBe 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.Expansion Hub InstallationThe Expansion Hubs may be located in the same or different wiring closets, and they may be located in a different wiring closet than the Main Hub. Use the following procedures for all Expansion Hubs.4 Check Main Hub LEDsThe 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. This indicates that the other end of the MMF cable is not yet connected to the Expansion Hub ports.
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.
