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.
•Standard wiring closet temperatures: 0-45° C
•Does not require special air conditioning
Space Requirements
The 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 Requirements
The 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 Installation
Underwriters Laboratory Installation Guidelines
Use 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 Precautions
Suggested 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 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).
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

plugs into the downlink connector, and the uplink coaxial cable
connector plugs into the uplink connector on the Main Hub.
Alarm Report Monitor
A 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).
