0.5 SAFETY NOTICES AND ADMONISHMENTS
This document contains safety notices in accordance with appropriate standards. In the interests of
conformity with the territory standards for the country concerned, the equivalent territorial admonishments
are also shown.
Any installation, adjustment, maintenance and repair of the equipment must only be carried out by trained,
authorized personnel. At all times, personnel must comply with any safety notices and instructions.
Specific hazards are indicated by symbol labels on or near the affected parts of the equipment. The labels
conform to international standards, are triangular in shape, and are coloured black on a yellow
background. An informative text label may accompany the symbol label.
Hazard labeling is supplemented by safety notices in the appropriate equipment manual. These notices
contain additional information on the nature of the hazard and may also specify precautions.
Warning:
These draw the attention of personnel to hazards that may cause death or injury to the operator or others.
Examples of use are cases of high voltage, laser emission, toxic substances, point of high temperature,
etc.
Alert:
These draw the attention of personnel to hazards that may cause damage to the equipment. An example
of use is the case of static electricity hazard.
Caution notices may also be used in the handbook to draw attention to matters that do not constitute a
risk of causing damage to the equipment but where there is a possibility of seriously impairing its
performance, e.g. by mishandling or gross maladjustment. Warnings and Cautions within the main text do
not incorporate labels and may be in shortened form.

1 GENERAL INFORMATION
The ComFlex-4500 Medium Power Distributed Antenna System (hereinafter called “ComFlex-4500”)
consists of Master Unit (MU) and Remote Unit (RU). The MU includes the MU Chassis, Power Supply
Unit (PSU), Fiber Optical Unit (FOU) and RF Unit (RFU). With a modular design, it can support up to 8
independent RF inputs and 8 Remote Units. The Remote Unit is designed with a compact and slim form
factor for easy installation; it is an integrated design and the power supply (LRU01-PSU) is separate from
RU.
The low signal transmission loss of optical fiber is applicable for long distance transmission. ComFlex-
4500 can support the optical transmission of up to 6.5dBo optical loss, equivalent to 8 miles fiber length.
Main feature:
Independent coupling port for uninterrupted network testing.
Modularized Master Unit supports flexible field upgrade and maintenance.
Independent gain control for each RF source.
High MTBF and low noise design with modular PSU and convection cooling.
RF module supports both simplex and duplex.
Compact slim Remote Unit for OPEX saving.
Supports multi-operator and mix mode application.
Optical link auto gain control.
Web based GUI for intelligent commissioning and configuration.
The figures below show the ComFlex Master and Remote unit enclosure.
