NOTE

VIRTUAL indicates a virtual cabinet. It can be an object in physical entity modeling, for example, a legacycabinet or a cabinet type not included in the existing cabinet types. It can also be an object when there is

no physical entity, for example, when a base station is installed in an open rack.

2.2.2 Subrack Numbering Rules

Entity subracks, such as BBU3900 subracks and RFU subracks, depend on cabinet types.

Extension subracks house optional peripherals, such as EMUs and GPS receivers. To ensure

subrack number consistency and scalability, a peripheral can occupy an extension subrack

independently.

Subrack numbers range from 0 to 254. Numbers of entity subracks cannot be changed. Numbers

of extension subracks can be defined by users. Table 2-8and Table 2-9describe how subracks

are numbered.

RRU 60 to 254 Entity subrack You are advised to comply with the

following rules when configuring

RRU subrack numbers:

l The RRU subrack numbers for

the same project must consistent

with each other.

l If a multimode RRU needs to be

configured in multiple modes, it

must be configured with the same

subrack number. Otherwise an

alarm is generated, indicating theconfiguration conflict.

l The RRU subrack numbers are

numbered starting from the

lowest band that the RRUs

support. Some subrack numbers

need to be reserved for capacity

expansion. For example, in a

network using the RRU3926 of

900 MHz, RRU3929 of 1800

MHz, and RRU3806 of 2100

MHz, the subrack numbers areassigned as follows: 60 to 69 are

assigned to the RRU3926s of 900

MHz, 70 to 79 are assigned to the

RRU3929s of 1800 MHz, and 80

NOTE

BBU board in a BTS supports automatic or manual configuration. If a BBU board supports automatic

configuration, the configuration of the board automatically takes effect when the configuration of the

cabinet housing the board takes effect. If a BBU board supports manual configuration, the configuration

of the board takes effect only after the board is manually configured. In a BBU of a BTS, the GTMU, FAN,

and UPEU support automatic configuration, whereas other boards require manual configuration.

All boards installed in a BBU must be configured.

For more details about the BBU board configuration, seeBBU3900 Hardware Description.

2.4 Typical Cabinet and Subrack Configurations for 3900

Series Base Stations

The configuration rules in this section apply to GBTSs, eGBTSs, NodeBs, eNodeBs, and co-

MPT base stations.

In multimode base stations, the configuration rules for cabinets, subracks, and common boards

in a BBU subrack are as follows:

SingleRAN





16



l The primary mode in a multimode base station is listed in descending order of priority:

GSM, UMTS, and LTE.

l All cabinets and the following subracks must be configured in primary mode: BBU, primary

mode-dedicated RF, PMU, EMU, TCU, CCU, and FMU. Only BBU subracks containing

the main control boards for secondary modes, secondary mode-dedicated RF subracks, andcabinets housing these subracks need to be configured in secondary modes.

l Cabinets and subracks configured in both primary and secondary modes must have

consistent cabinet and subrack numbers. Otherwise, parameter configuration conflict

alarms will be generated.

l In a BBU subrack, the UPEU, UEIU, and FAN can be configured in two modes, the UCIU

and UTRPc can be configured only in one mode, and the USCU can be configured in either

one mode or two modes.

Modifying the Baseband Board Configuration

Run the MOD BBPcommand to modify the baseband board configuration.

Pay attention to the following when modifying the LBBP configuration:

l Before modifying the working mode of the LBBP for the existing activated cell, ensure

that the eNodeB supports the modified working mode and that there are sufficient idle

resources (see the cell specifications of the LBBP). Otherwise, the cell cannot be activated.

l LBBPs in FDD mode support 1T1R, 1T2R, 2T2R, 2T4R, and 4T4R FDD cells.

l LBBPs in TDD mode support 1T1R, 2T2R, 4T4R, and 8T8R TDD cells.

l If an RRU chain/ring in load sharing mode is configured on LBBPs and the chain head and

tail belong to different LBBPs, the working mode of the LBBP cannot be modified.

l If the RRU/RFU cannot set up links or work at the maximum line rate after the LBBP is

blocked/unblocked, run the STR CPRILBRNEGcommand to manually initiate

negotiation.

l To block or unblock the LBBP, change the value of the ADMSTATEparameter in the

BLK BRDor UBL BRDcommand, respectively. After the board is blocked, ALM-26210

Board Blocked will be reported and the board will not provide services. After the board is

unblocked, the alarm will be cleared.

interrupt services on base stations of other modes.

Resetting GBTS BBU BoardsRun the RST BTSBRDcommand to reset a specified BTS BBU board.

Reset using this command consists of soft reset and power-off reset, which are specified by

corresponding parameters. If power-off reset is selected for a multi-mode base station, boards

in the BBUs of other modes are reset.

The boards that support soft reset are as follows: Ordinary boards

The boards that support power-off reset are as follows:

l GTMU

l UBRI

SingleRAN

Resetting BBU Boards in Soft Reset Mode in GBTSs, NodeBs, eNodeBs, or Co-MPTBase Stations

If a board has a fault that cannot be rectified, soft reset is required. Soft reset takes a relatively

short time.

Run the RST BRDcommand to perform a soft reset.

NOTE

USCU, FAN, UPEU, and UEIU do not support soft reset.

After the RST BRDcommand is executed, the BBU Board Maintenance Link Failure alarm and

the Board Startup event alarm are generated. Run the DSP BRDcommand to check the values

of AvailabilityStatusand OpState. If the value of AvailabilityStatusis Normaland the value

of OpStateis Enabled, the board has started up properly and the fault has been rectified.

Resetting NodeB/eNodeB BBU Boards in Power-off Reset ModeIf soft reset fails, power-off reset is required. Power-off reset takes a relatively long time.

Run the RST BRDPWROFFcommand to perform a power-off reset.

NOTE

USCU, FAN, UPEU, and UEIU do not support power-off reset.

After the RST BRDPWROFFcommand is executed, the BBU Board Maintenance Link Failure

alarm and the Board Startup event alarm are generated. Run the DSP BRDcommand to check

the values of AvailabilityStatusand OpState. If the value of AvailabilityStatusis Normaland

the value ofOpStateis Enabled, the board has started up properly and the fault has been rectified.

5.4.2 Querying BBU Board Information

Querying GBTS Board Information

Run the DSP BTSBRDcommand to query the running status of a GBTS board.

Querying Board Information in eGBTSs, NodeBs, eNodeBs, or Co-MPT BaseStations

Step 1 Run the DSP BRDcommand to query the running status of a board in eGBTSs, NodeBs,eNodeBs,

base station cabinets and subracks (including the bbu subrack) configuration(sran8.0 03)[1]
