Huawei H35-481_V2.0 Dumps

According to Huawei official documentation, using the MAE-Deployment (radio network planning data file) method is recommended for modifying the cell bandwidths across the entire network during gNodeB data reconfiguration. This method allows for the efficient and accurate modification of cell bandwidths by using a radio network planning data file to update the configuration of multiple gNodeBs at once.

According to Huawei official documentation, the following are possible causes of NRDUCELL unavailability: A. RF fault B. BBP fault C. Insufficient CPRI bandwidth D. Clock exception. The RF, BBP, and CPRI bandwidth are all important factors that contribute to the availability of the NRDUCELL. If there is a problem with any of these components, it can cause the NRDUCELL to become unavailable. Additionally, a clock exception, such as an issue with the timing or synchronization of the cell, can also cause the NRDUCELL to become unavailable.

NRDUCELL unavailability can be caused by an RF fault, a BBP fault, insufficient CPRI bandwidth, or a clock exception. According to this page, these are all possible causes of NRDUCELL unavailability.

The Slot1 on both the BBU5900 and BBU3910 retains the same physical position. Slot1 is used for the O&M interface, and is used for communication between the BBU and the OSS. It supports the SFP/SFP+ optical modules for O&M communication.

The UBBP board is added to the base station when it is reset, and you need to log in to the LMT again in order to access the new UBBP board. The UBBP board is used for configuration, monitoring, and maintenance of the base station.

According to Huawei's official documentation, when the UBBP (Universal Baseband Processing) board is added, the base station is reset and you need to log in to the LMT (Local Management Terminal) again. The addition of other boards (OUMPT, UPEU, UEIU) may not require a reset and re-login.

The segmentation method is the most important method for isolating faults on the transport network. Different methods are used for different fault types, such as Optical Time Domain Reflectometry (OTDR) for fiber faults, Radio Frequency Interference Measurement (RFI) for radio interference, and Signal-to-Noise Ratio (SNR) for signal noise. By segmenting the network, faults can be easily identified and isolated. Reference:

According to the Huawei official documentation, a gNodeB supports up to 4 OM channels at most. These channels can be used to monitor and manage the gNodeB remotely. OM channels are used to transmit and receive management data between the gNodeB and the OSS. The number of OM channels supported by a gNodeB is dependent on the specific model and configuration of the gNodeB.

The BLK BRD command can be used to block the BBP, DUPEU and AAU boards. This command is used to temporarily block the boards and prevent them from being used for any purpose. The RRU board cannot be blocked by running this command.

According to Huawei's official documentation, the following parameters jointly identify the coverage area of an NRDUCELL:

• NRDUCELId
• NrDuCellTrpId
• NRDUCELUd (Source: Huawei 5G Base Station NR-DU Configuration Guide)

During a cell search, a UE uses synchronization signals to synchronize to a cell and obtain basic system information. The synchronization rasters that can be used by a UE during a cell search are:

A. 17.28MHz: This is the synchronization raster that is used for the primary synchronization signal (PSS) and the secondary synchronization signal (SSS) in 5G NR.

B. 1200kHz: This is the synchronization raster that is used for the primary synchronization signal (PSS) and the secondary synchronization signal (SSS) in 4G LTE.

C. 1.44MHz: This is the synchronization raster that is used for the cell-specific reference signal (CRS) in 4G LTE.
