NOTE
You can save either or both of the cross certificate and operator's root CA certificate to the USB storage device. Step 2 Obtain the digital certificate required for the security GW. Ensure that Huawei root CA certificate
and Huawei CRL file are configured on the security GW. ----End
5.2.4 Obtaining the Files Required for the eNodeB Commissioning
Through the USB Storage Device
Before the local eNodeB commissioning through the USB storage device, you need to save the required files in a specified directory in the USB storage device.
Prerequisite
l The USB storage device is ready.
l The eNodeB software package and data configuration file are available.
l When the security GW is deployed on the network, the common configuration file and
digital certificate to be imported to the eNodeB are saved in the USB storage device. For details, see 4.2.6 Arranging for the Files in the USB Storage Device Required for the eNodeB Commissioning on the M2000.
Context
The eNodeB software package is ready, and can be downloaded from http:// support.huawei.com/.
The name of the data configuration file should be CFGDATA.XML. The file name is case sensitive. Complete the configuration by referring to the eNodeB Initial Configuration Guide. Then, save the data configuration file in the local computer.
The name of the common configuration file should be PreInfo.xml. The file name is case sensitive.
Procedure
l When the security GW is not deployed on the network, save the files required for local commissioning in the following specified paths in the USB storage device. The save path is case sensitive.
File Specified File Path in the USB Storage Device
eNodeB software package usb:\eNodeB\Software\ Data configuration file usb:\eNodeB\
l When the security GW is deployed on the network, save the files required for local commissioning in the following specified paths in the USB storage device. The save path is case sensitive.
File Specified File Path in the USB Storage Device
Common configuration file usb:\eNodeB\ Cross certificate granted by
Huawei
usb:\eNodeB\Certificates\CrossCACert\ Operator's root CA
certificate
usb:\eNodeB\Certificates\CACert\ Operator's CRL file usb:\eNodeB\Certificates\CRL\ eNodeB software package usb:\eNodeB\Software\
Data configuration file usb:\eNodeB\

5.3 Downloading and Activating the Software and Data
Configuration File Through the USB Storage Device
This section describes how to download and activate the eNodeB software and data configuration file through the USB storage device. The eNodeB automatically downloads the software and data configuration file from the USB storage device, and then activates them. The software and data configuration take effect after the eNodeB resets.
Prerequisite
The USB storage device is ready for use. The required files are saved in the USB storage device. For details, see 5.2.4 Obtaining the Files Required for the eNodeB Commissioning Through the USB Storage Device.
CAUTION
If one USB storage device is used repeatedly, the target eNodeB software and data configuration file in the USB storage device should be updated before the USB storage device is used for an eNodeB deployment.
When you save the eNodeB software and data configuration file to the USB storage device, ensure that the locking switch on the USB storage device is disabled. In other words, the USB storage device should be writable.
Context
When the LMPT of the BBU3900 is started, it automatically detects the USB storage device, reads the related software and data configuration file in the USB storage device, and verifies the file names and formats.
If you install the BBU before installing the RRU, you can install and power on the RRU during the process of BBU software downloading. After the BBU software is downloaded/activated successfully and the RRU is powered on, you can reset the LMPT to start the automatic upgrade of the RRU software.
You should pay attention to the following points when you download and activate the software and the configuration file through the USB storage device:
l If the USB storage device contains the common configuration file of the site, digital
certificate and eNodeB software, the eNodeB parses the common configuration file, loads the digital certificate, and then downloads and activates the eNodeB software and data configuration. If the eNodeB cannot parse the common configuration file, it does not proceed with the subsequent process.
l If the USB storage device contains only the eNodeB software and data configuration, the
eNodeB downloads and activates the eNodeB software, and then downloads and activates the data configuration.
l If the eNodeB software or data configuration file is missing in the USB storage device, the
eNodeB performs the following steps:
– If the eNodeB software is missing in the USB storage device, the eNodeB
commissioning through the USB storage device is not performed.
– If the data configuration file is missing in the USB storage device, the eNodeB upgrades
to the minimum configuration of the target version and skips the download and activation of data configuration.
l If the eNodeB software upgrade fails, the eNodeB rolls back to the pre-upgrade version. l Before downloading and activating data configuration, the eNodeB does not check the
compatibility between the data configuration file and the eNodeB software version. The eNodeB performs the following activities:
– If the eNodeB software is upgraded successfully but is not compatible with the data
configuration file, or if the download and activation of data configuration fail, the eNodeB uses the minimum configuration of the target version.
– When the active eNodeB software is consistent with the target software version,
software upgrade is not performed. After the eNodeB resets, if the active eNodeB software is not compatible with the data configuration file or if the download and
activation of data configuration fail, the eNodeB uses the data configuration of the earlier version.
l If any of the following situations occurs, the eNodeB would not download or activate the
eNodeB software or data configuration file from the USB storage device.
– The directory or the file does not exist.
– The eNodeB software is missing in the USB storage device, and therefore the software
and data cannot be downloaded or activated.
– The target software version is consistent with the active eNodeB software, and therefore
the eNodeB software is not downloaded or activated. The download and activation of data configuration is still normal.
– The data configuration file is consistent with the active data configuration, and therefore
data configuration is not downloaded. The download and activation of the software is still normal.
Procedure
Step 1 Insert the USB storage device into the USB port on the LMPT of the BBU3900, as shown in
