4.1 PRE-COMMISSIONING 

TASKS 

After equipment installation, perform the following steps before equipment powering and 
commissioning, check that the expected voltage, current, and power levels do not violate any ratings. 
Double check all connections including ground before applying power. Do not manipulate circuits or 
make changes when power is applied: 

 

  Visually inspect the power connection within the equipment. Ensure that the power cable is 

correctly and securely connected, including grounding wire, RF cable and optical cable.  

  Check grounding connection and verify that the ground resistance is less than 5

.

 

  Connect the equipment to the PC installed with OMT software.  

  With the MU switched on, RU installed and all cablings connected, apply power to the RU by 

switching on the PSU switch on the integrated PSU.  

  Monitor the initialization of the MU though the LEDs on the front panel of MCU unit, while for RU, 

it is through the LEDs on the MCU unit integrated. Refer to detailed LEDs information in the next 
section.
