RU common Alarm is as follows:

Board communication link interruptedOutdoor lightning protection box alarm Remote Antenna Vswr Alarm Remote antenna over VSWR alarm Improper DPD running status

RU Alarm

RU AlarmBoard communication link interrupted

Advice ：Maintenance team meet this alarm. First check optical fiber, if not ok, check the RU or FS board.Change order ： optical interface 、 optical fiber 、 RU、 FS board 。

RU Alarm

Remote Antenna VSWR AlarmRemote antenna over VSWR alarm

Advise ：The same as V3 VSWR alarm 。 If VSWR of antenna is ok, need to change the RU. 。If the alarm is over VSWR alarm, reset the RU after you do the active, the alarm can disappear.

About RU Alarm

Outdoor lightning protection box alarm

If happening at SWAP time ， this alarm maybe due to cable connection of LPB is wrong. If happening at Maintenance time, this alarm may be due to LPB is fault. Maybe need to change the LPBHere is the cable connection 。 Refer to this map。

Improper DPD running status

This alarm will affect network quality 。 Need to reset the RU, otherwise should be change the RU.

About CC AlarmThose alarm are due to the transmission. You should check the transmission.If you want to re-patch the EI ， SDR E1 Refer to this map

One thing more ， if Relay circuit fault appear on CC board ， the alarm due to Lucid Channel is not working of eass. Check the MISSU of MISU.

UBPG & FS Alarm

If these two alarms appear ， RU should hasBoard communication link interrupted alarm 。 Check the RU,the alarm will be disappear after RU running normal 。

BBU Board & FCE & Fan Alarm

Board communication link interruptedIf BBU or FCE have Board communication link interrupted alarm ， the board or FCE is fault. Change the fault board 。

Fan alarmIf Fan alarm appear on FCE ， should change the Fan or subrack 。 8700 Schematic diagram。

Dry Contact Alarm

SDR Dry contact alarm have two parts ， One is from FCE ， the other is from SA 。 You can see the B/W tableFCE dry contact alarm is from SDR itself. Like ： BC door alarm 、 water proof 、 SMOG faultSA dry contact alarm is like V3.If you want to repatch the cableRegard this map。

4 、 Distinguish and exchange between RRU/RSU4 、 Distinguish and exchange between RRU/RSU

You can see the difference between RSU60 and RSU60E. R8860 and R8860E outlook 。

RSU60E and R8860E are advanced RSU60 and R8860 RF unit.

They change each other should change the configuration of BTS and BSC both end and reload the software.

Note: The RSU60 can not replace RSU60E ， or R8860 replace R8860E 。
