7.2.2.1.4 HE RFU commissioning
If a BCU is being used in the system, the BCU should be commissioned before commissioning the HE RFU.
For RFU commissioning, the user will need to calculate the DL input commissioning level. Refer to section
7.2.2.1 to for information to determine the DL input commissioning level.
7.2.2.1.4.1 HE RFU commissioning Procedure
x Go to Install page of RFU on the Web-GUI
Figure 7-7 RFU Install Window
x Enter HE RFU downlink input commissioning level
- Input range: 0~+25dBm, 0.5dB step
x Press the “Apply” button
x The attenuation levels will be set automatically based on DL Input Commissioning Level that is selected.
x Checks to see if DL input is low.
- During the commissioning routine, if DL input level is 10dB less than commissioning level, a
popup message will appear stating that DL input is low. If this is the case, then there is a chance
that the “back-off” value needs to decrease breathing room.
x Checks to see if ALC is active.
- During the commissioning routine, if ALC is activated, a popup message will appear stating that
ALC is running. If this is the case, then there is a chance that the “back-off” value needs to be
increase to allow more breathing room.
x Checks to see if the RFU has any alarms.
- If a soft fail is present, the system will prompt the user whether or not they would like to
continue.
- If hard fail is present, the commissioning process will stop immediately.
x Commissioning is successfully completed.
