The input range of MU RF unit is 10~30 dBm.   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 8 miles, with a maximum path loss of 6.5dBo.  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.

USER MANUAL FOR COMFLEX 6800  ENU STATUS : 1-0-0 Copyright - refer to title page Page 63     Step 8: Click   to enter to [Finish] page after finishing RU setup.   Note: As the system calibration process is calibrated for single channel, so if there is more than one same band input, because of the power superposition, the band total output power will higer than target DL output power after the calibration is complete.  The calibration work is mainly to set device to reach it’s theoretical gain, so when there are two or more same  bands access  into  and  they  have  the  same  input  power  level,  each  channel  will  reach it’s  rated power, so the total output power will be (input A+gain) + (inputB+gain)+…+(inputN+gain). For example, if there are two 1900MHz bands acess to MU, each has 10dBm input power, the total output power of RU 1900MHz will be 30dBm+30dBm=33dBm.  Refer to the method below for the gain adjustment: Suppose a band  with N independent inputs, each input signal power are all X dBm. Apparently, there exists the following relationship between input and output after finished auto communication on WEB GUI: X dBm + Gain = 30dBm, then the total output power for N channels access is X dBm + Gain + 10*Log(N) = 30 + 10*Log(N), so Users need to set 10*Log(N) RFU ATT on WEB GUI for each channel.

Apply climatic protection to the system under severe environment. Optical TX Alarm   Test MU transmit optical power    Replace FOU if transmit optical power is less than -7dBm Optical RX Alarm   Clean optical cable connector with pure alcohol first , reconnect and see if alarm disappears   Use Optical Power Meter to test received optical power   If received optical power is lower than -10dBm, test whether RU transmit optical power is normal (3~5dBm)   Check if optical loss of fiber link is higher than 6.5dBo DL Input Power Overload Alarm  Test  DL  input  power  of  MU,  if  it  is  higher  than  +33dBm,  lower  the  power  below  30dBm  by decreasing source output power or adding an external attenuator with proper attenuating value.  Table 17: RU Alarms Diagnosis Alarm condition Diagnosis External Alarm  Check to make sure if the external device connected is working normally Over- Temperature alarm   Check device temperature on WEB GUI   If device temperature e is over threshold, make sure environment temperature is within the envireonment temperature range that RU supported (-20~50℃). Apply climatic protection to the system under severe environment. Optical TX Alarm   Test RU transmit optical power    Replace FOU if transit optical power is less than 0dBm Optical RX Alarm   Clean optical cable connector with pure alcohol first, reconnect and see if alarm disappears   Use Optical Power Meter to test received optical power   If received optical power is lower than -14dBm, test whether MU transmit optical power is normal (-4~-2dBm)   Check if optical loss of fiber link is higher than 6.5dBo DL PA alarms    Check PA Service Status on WEB GUI RU page,    If it is [Recovery], reset PA on WEB GUI Management page, then read RU output power: If output power is exceed threshold, need to reduce gain or input power; if output power is normall, check whether antenna port VSWR is too high.   If it is [Shutdown], Refer to PA Shutdown Alram DL Output Power Overload Alarm   Check if output power is exceed the threshold (32dBm for LRU, 39dBm for MRU)   Decrease the gain to reduce the output power PA Shutdown Alarm   Make Sure the environment temperature is -20~50℃   Reset PA, if PA service status turns to [Recovery], and then refer to DL PA Alarms. If PA still shutdown, the PA module maybe damaged, please contact with Comba to replace the RU. LNA Alarm Uplink LNA modual damaged, please contact with Comba to replace the RU.  End of Section
