4 COMMISSIONING
4.1 PRE-COMMISSIONING TASKS
After equipment installation, perform the following steps before equipment power up and commissioning.
Verify the incoming power source voltage, current, and power levels do not violate any ratings. Double
check all connections before applying power. Do not manipulate circuits or make changes with power
applied.
•
Visually inspect the power connection within the equipment. Ensure that the power cable is correctly
and securely connected, including grounding wire and RF cable.
•
Check grounding connection and verify that the ground resistance is less than 5
Ω
.
•
Connect the equipment to the PC installed with OMT software.
•
With the equipment installed and cables connected, apply power to it by switching on the PSU switch.
•
Monitor the initialization of the equipment through the indicator LEDs on the enclosure bottom. Refer to
detailed LEDs information in the next section.
4.2 EQUIPMENT LED INDICATORS
Three diagnostic LED indicators are located on the bottom of the enclosure. Each LED indicates the status
of a particular function:
Identifier Colour
Indication
MODEM
Green
Modem status. ON = initialization and normal communication;
OFF = initialization finished and abnormal communication.
RUN
Green
MCU Operation. ON = normal operation; flashing = normal
operation starts; OFF = no power supply / MCU operating
problem.
ALM
Red
System Alarm status. ON = Failure Alarm; OFF = normal
operation.
Table 7: MCU LEDs
Note:
1. Indicators COMM, PWR and ALM are flashing when the equipment is powered ON, indicating the
system self-check. After about 60 seconds, indicator RUN will flash to indicate the equipment is
operating normally. At this point, the OMT/OMC on-line connection can commence.
2. Slave Unit requires 30-60 seconds to complete initialization, while Master Unit requires 60-120
seconds to complete initialization.
3. In addition, indicator COMM flashing means no communication between Master and Slave units.
When it is off, it means no slave unit is connected.
