You also need the following equipment and supplies:

• Cable and connectors already installed and terminated. LGC Wireless
recommends plenum-rated Category 5 (CAT 5) or better, Unshielded Twisted
Pair or Shielded Twisted Pair (UTP/STP) and Multi-Mode Fiber (MMF) cable.

Main Hub

• 19” equipment rack space in the wiring closet

• Phillips screwdriver

• MMF cleaner recommended by the cable manufacturer

Inspect the equipment and supplies before you start the LGCell installation. Make
sure that the UTP/STP and MMF cables are terminated correctly and that the
connectors are clean and free of dust or oil (use recommended cleaner as necessary).
If you have any problems, call LGC Wireless at 1-800-530-9960 (U.S. customers)
or [phone] (international customers).

ii LGCell Installation Procedure

About This Manual

This Installation and Reference Manual describes the following LGCell products:

• LGCell 800 MHz AMPS/TDMA/CDMA/iDEN

• LGCell 900 MHz GSM

• LGCell 1800 MHz DCS

• LGCell 1800 MHz Korean PCS

• LGCell 1900 MHz TDMA/CDMA/GSM

• LGCell Dual Band 900 GSM/1800 DCS

System operation for these products is identical. The only differences between the
products are the operating frequency range, access scheme (TDMA, GSM, etc.) and
certain operating parameters (gain, etc.). In this manual, distinctions between
different systems are clearly indicated.

This section provides an overview of this Installation and Reference Manual,
describes conventions, and provides other useful information.

If you plan to connect your LGCell system to more than one radio or base
station, you also need the Integration Module Installation and Reference
Manual.

• LGC
replaceable through LGC Wireless. Please contact us at 1-800-530-9960. For
international customers, please contact us at [phone].

• Never input an RF signal to the Main Hub Duplex port that is higher than those
defined on page 17 in

• Although modeled after an Ethernet/LAN-like architecture and connectivity,
LGC
not intended to connect to Ethernet data hubs, routers, cards or other similar
data equipment.

• For improved air circulation, be sure to leave at least one inch (25 mm) of
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 a one inch of
clearance from the bottom.

vi About This Manual

• When you connect the Multi-Mode Fiber (MMF) Optical Cable, take the same
precaution as if installing Ethernet network equipment. All optical fiber ST
connectors should be cleaned according to the cable manufacturer’s
instructions.

• When you connect a radiating antenna to an RAU, DO NOT over-tighten the
SMA connector. Firmly hand-tightening the connector is adequate.

To reduce the risk of fire or electric shock, do not expose this
equipment to rain or moisture.

Fiber Port Safety Precautions

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.
