3.2 SITE PLANNING CONSIDERATIONS
3.2.1 SITE PLANNING
Site Considerations
The MU can be located indoors to facilitate coupling of BTS signals and power supply connections. The
ALC range of received BTS signal is -10~10 dBm. Hence, an appropriate coupler must be used according
to the BTS output power.
The site consideration for RU is listed below:
The distance between the service antenna of RU and coverage area should satisfy line of sight
requirements for maximum coverage area.
The maximum fiber length is 20km, with a maximum path loss of 10dB.
The system delay of the optical system must be taken into consideration when there are neighboring
BTS sites overlapping in coverage.
Installation Location
Mounting surface shall be capable of supporting the weight of the equipment.
In order to avoid electromagnetic interference, a proper mounting location must be selected to minimize
interference from electromagnetic sources such as large electrical equipment.
Environmental
Humidity has an adverse effect on the reliability of the equipment. It is recommended to install the
equipment in locations having stable temperature and unrestricted air-flow.
The installation location for the system should be well ventilated. The equipment has been designed to
operate at the temperature range and humidity level as stated in the product specifications.
Powering
The power supply unit (PSU) provides power to all modules within the equipment. Depending on the
product variant, it is recommended that the PSU operates on a dedicated AC circuit breaker or fused
circuit.
Grounding Requirement
Verify that the equipment has been well grounded. This includes antennas and all cables connected to the
system. Ensure lightning protection for the antennas is properly grounded.
Cable Routing
Depending on equipment configuration, a variety of types of cables are connected to the MU and RU:
coaxial cables, optical fibers, power cable, communication cable, and commissioning cable. Where
applicable, ensure cables are properly routed and secured so that they are not damaged.

3.5 EQUIPMENT CONNECTION
3.5.1 GROUNDING CONNECTION
Ground connection
To ensure safe operation of the product, a ground (earth) connection is required. For single phase AC
power source, the product must be grounded by connecting the “earth wire” of the power cord to the
ground terminal of the AC supply. For operating this product with DC power system (such as rectifiers),
the product should not be connected to power systems that switch open the return lead because the
return lead could function as the ground (earth) connection for the equipment.
Protective Ground Connection
The enclosure must be grounded securely by connecting a copper wire (CSA 16mm2) to the grounding
terminal on the equipment/rack, and the other end to a protective ground (i.e. building earth point). An
internationally acceptable colour code of the ground connection wire is green/yellow.
Such a ground connection implements the “Protective Ground Connection”, and must be connected to the
equipment at the designated ground point. In general, do not connect the supply before establishing an
adequate ground (earth) connection.
RA-7E00 Grounding Connection
The equipment must be grounded securely. Connect a copper wire to the grounding terminal on the
mounting tab/enclosure, and connect the other end to a protective ground (i.e. building earth point). An
internationally acceptable coloring code of the ground connection wire is green/yellow.

severe environment.
Door Open Alarm
Check whether the enclosure door is closed.
Shutdown Alarm
Alarm occurs when automatically shut off the system. Turn on the
system and check if the DL output power overload alarm persists,
adjust the DL output power overload threshold to a proper value.
Optical TX/RX Alarm
The optical power at the TX/RX port of the Optical TX/RX Module is
lower than the minimum requirement, which is resulted by the faulty
of the optical TX/RX part of Optical TX/RX Module or damaged
optical fiber link. If so, replace the optical TX/RX module. If not,
check the working status of the optical fiber to eliminate the alarm.
UL LNA, DL PA alarms
Check power and signal connections of respective modules. If the
power and signal wire connections are OK, then the respective
modules may be faulty. Replace the faulty modules and return it to
the factory for repair.
DL Input Power Overload
Alarm
Eliminate alarm by correct setting of DL Input Power Overload
threshold. If the setting is OK but alarm persists, the DL input power
might be higher than the threshold. Decrease the gain to reduce the
input power or replace the coupler with a new one of high coupling
effect.
DL Output Power Overload
Alarm
Eliminate alarm by correct setting of DL Output Power Overload
threshold. If the setting is OK but alarm persists, the DL output
power might be higher than the threshold. Decrease the gain to
reduce the output power.
DL Output Power Low Alarm
Eliminate alarm by correct setting of DL Output Power Low
threshold. If the setting is OK but alarm persists, the DL output
power might be lower than the threshold. Increase the gain to high
up the output power.
