6.4 Checking the Status of the LEDs and Rectifying the
Faults
This section describes how to check the operating status of the LEDs according to the states of
the LEDs on the modules of the base station.
Context
LED status of functional eNodeB
If the status of the LEDs on the boards and auxiliary devices are the same as that shown in
6-7, you can infer that the base station runs properly.

Table 6-7 LED status of the functional base station

LED
RUN LED on each board in the base station
ALM LEDs on the GTMU/WMPT/LMPT/WBBP/LBBP/
UERI/UTRP/PMU/AFMU/EMUA/MRFU/RRU3908
STATE LED on the FAN of the BBU3900
CPRI LED on the GTMU/WBBP/LBBP/MRFU/RRU3908 ON (green)
VSWR LED on the MRFU/RRU3908
If the transmission is unavailable in the local USB commissioning scenario, the GBTS automatically resets at
intervals of 10 minutes. During this period, you need not check the status of the ALM LEDs on the MRFU/
RRU3908 working in the GSM system, GTMU, and UBRI. Check the status of co-cabinet MRFU/RRU3908
modules when you check the hardware status of the NodeB or eNodeB.
