Radiation Warning
Precautions
This section describes general safety precautions for LGCell products and safety
precautions for Fiber Ports on the hubs.
General Safety Precautions
The following precautions apply to LGCell products.
• LGCell has no user-serviceable parts. Faulty or failed units are fully
replaceable through LGC Wireless. Please contact us at 1-800-530-9960. For
international customers, please contact us at +1-408-487-2400.
•Never input an RF signal to the Main Hub Duplex port that is higher than those
defined on page17 in Section 2, LGCell Equipment.
•Although modeled after an Ethernet/LAN-like architecture and connectivity,
LGCell units (Main Hub, Expansion Hub, and the Remote Antenna Unit) are
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.
•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.
The antennas should be installed to provide at least 20 cm from all
persons to satisfy Radiofrequency Radiation Exposure requirements
of FCC 2.1091.
To reduce the risk of fire or electric shock, do not expose this
equipment to rain or moisture.
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 –
iv
Compliance Information.
•Viewing fiber: Observe the following warning about viewing fiber ends in
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.
•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.
