在項目上做過所有基站告警的統計分析,對于7602,確實就是這兩種情況,但對于風扇的告警,可能是比較敏感,比如風扇的速度慢了,低于門限值,也會出告警.所以一要看附加信息,二要做統計分析,看那種情況出現次數多,再對應基站實際狀況找原因,而不是說告警掛在那里好不好看的問題.

不妨勤快一點,把NED的描述帖上來,在看看,雖然描述一大堆,對于METROSITE ULTRASITE兩種站型,也就是同步,功率,風扇,溫度,傳輸,連接,數據,總線等幾個方面的原因.各個項目的情況不一樣,比較多的情況應該只有2-3鐘.

is below -10C.

Fault reason: Fan unit is broken. 風扇損壞
Instructions:
1.Check whether the fan unit is installed.
2.When there is a fan unit installed, check if something has jammed
the fan unit and remove the jamming object. Otherwise replace the
fan unit.

ULTRASITE:對于ULTRASITE來講：

Fault reason: Power unit temperature is low.功率單元溫度太低
Instructions:
1.Ensure that the ambient temperature of the base station is
within specified limits.
2.Check that the heater is working properly if equipped.

3.Replace the transmission unit.
Note: An alarm is activated when the transmission
unit's internal temperature is below -10C.

Fault reason: Power unit has lost connection to temperature sensor.
Instructions:功率單元與溫度傳感器之間的連接損壞。

1.If another slot in the cabinet is empty, move the
power unit into the empty slot.
2.The temperature sensor is probably broken.
Temperature changes cannot be measured.
Replace the power unit.

Fault reason: Transmission unit has lost connection to temperature sensor.
Instructions:傳輸單元與溫度傳感器之間的連接損壞。

1.Temperature sensor is probably broken.
Temperature changes cannot be measured.
Replace the transmission unit.

Fault reason: BOI detected that connection to transmission unit is lost.
Instructions:BOI檢測到與傳輸單元之間的連接損壞。
1.Open the Nokia UltraSite BTS Hub Manager and
check the active alarms. If this base station or
other base stations beyond it otherwise operate
properly, there is no need for an immediate
repair. However, the transmission alarms for the
faulty unit are not reported to the BSC nor the
Nokia BTS Manager.
2.Reset the faulty transmission unit.
Note: Resetting the unit affects the traffic routed through it.
3.If the alarm reappears after the transmission unit
reset, switch the cabinet power off and on.
4.If the alarm reappears after the recovery actions
above, replace the faulty transmission plug-in unit.

Fault reason: Cooling fan is broken. 風扇損壞
Instructions:
1.If something has jammed the cooling fan unit,
remove the jamming object.
2.Check which fan is giving the alarm from the
supplementary information (rack/shelf/slot).
3.If the TSxx fan is alarming:
. Remove the TSxx in front of the fan. If the fan
starts working, the removed TSxx is broken.
. If the fan still does not rotate after the first
TSxx was removed, reinsert it and remove
the second TSxx. If the fan starts rotating,
the second TSxx is broken.
. If the fan does not work after the TSxx
removal test, the fan is broken and must be
replaced.
4.For other fan alarms, replace the corresponding fan unit.
5.Otherwise, replace the BOI.
Note: This alarm is related to fans located in the back
of the cabinet.

Fault reason: Cabinet fan is broken.機柜風扇損壞
Instructions:
