3 Software Upgrade

The NPU holds the following versionsTwo versions (Main and Shadow) for itself

Four file versions for the AUs

Four file versions for the SUs

Each AU or SU holds within two versions (Main and Shadow)

When an upgrade needs to be performed First, the file version is transferred to the NPU

Second, the unit (AU or SU) is set to download the version from the NPU

Third, the unit (AU, SU or NPU) is set to reboot and load the shadow version

Fourth, the unit (AU,SU or NPU) is set to mark the running version (shadow) as

main version

8 Software Upgrade

Verify that IP connectivity is working properly by pinging the NPU (DATA or MGMT port)

In the command prompt enter the following command:ping <NPU IP Address>

e.gping 10.10.10.1

Download the file to the NPU (DATA or MGMT port)In the command prompt enter the following command:

tftp -i <NPU IP Address> PUT <Path><File Name>e.g

tftp -i 10.10.10.1 PUT c:\Firmware_Files\AU_1_5_1_33.bz

The transfer operation is completed when the following message appears:

"Transfer successful: XXXXXX bytes in YY seconds, ZZZZZZ bytes/s"e.g

Transfer successful: 2598936 bytes in 13 seconds, 199918 bytes/s

Verify that the software is successfully identified by the NPU To check an NPU version

To check an AU version

To check an SU version

9 Software Upgrade

To upgrade an NPU skip to the next step, set the unit (AU or SU) to download a file from the NPU and enter the file name to download

Set the unit (NPU, AU or SU) to run from the shadow version

The unit reboots and loads the shadow version

In order to load the new software permanently, the unit (NPU, AU or SU) needs to set the shadow version as main

At the next boot the unit marks the shadow version as main

10 Configuration Backup (NPU)

The Backup option enables creating a backup file of the entire Base Station/Micro Base station configuration or some of the configuration

The backup file can be one of the following format

Full - the entire NPU/µBST configuration (except to the basic IP parameters of the MGMT and DATA ports) - backup.res

Profiles - all the profiles associated with services (Service Profiles, Forwarding Rules, Priority Classifiers, QoS Profiles) - profiles.res

Profiles and Services - all the profiles and configurations associated with service (General Service parameters, Subscribers, Services, Service Profiles, Forwarding Rules, Priority Classifiers, QoS Profiles) - profiles_srvcs.res

Filtering - all the configurations of Filtering Rules, Interface Filtering and MAC Address Deny List. This option is not applicable for units operating in IP CS Switching Mode – filtering.res

Traps - the configuration parameters for all traps - Traps_Config.res

BS License File - all license related information, including total, available andused licenses, CPEs with allocated licenses (local or permanent), CPEs with grace or temporary grace licenses and CPEs for which grace license expired -BSLicense_<Management Port MAC Address>.res

If a backup file already exists in the NPU/µBST, a message appears asking whether to overwrite the existing file

If there was an error in the process of creating the backup file, an error message will

be displayed, indicating the reason

Once the backup file has been created, it can be uploaded using a DOS based TFTP Client application to a target directory

The file is encrypted and cannot be editedHowever, it can be downloaded to other NPU(s)/µBSTs using a DOS based TFTP

Client application

Note: A µBST cannot be downloaded with NPU backup and vice versa

Verify that IP connectivity is working properly by pinging the NPU (DATA or MGMT port)

In the command prompt enter the following command:ping <NPU IP Address>e.gping 10.10.10.1

Create a backup file

Using the monitoring program

Select the required backup file

Confirm the command

"Creating the Backup…" message appears

The process has completed successfully when the following message appears:"Creating the Backup OK"

Storing the backup file in a local computer – Requires TFTP Server (e.g Solarwinds)

In the command prompt enter the following command:tftp -i <NPU IP Address> GET <File Name> <Path>e.gtftp -i 10.10.10.1 GET backup.res c:\NPU_Backup\

The transfer operation has completed when the following message appears:"Transfer successful: XXXXXX bytes in YY seconds, ZZZZZZ bytes/s"e.gTransfer successful: 2598936 bytes in 13 seconds, 199918 bytes/s

14 Configuration Backup (SU)

The Backup option enables creating a backup file of the entire SU configuration

The SU downloads/uploads the configuration file to/from a configured TFTP server

Prior performing the backup a message appears asking whether to execute the backup process

The file is encrypted and cannot be editedHowever, it can be downloaded to other SUs using a DOS based TFTP application
