2Objectives

Upon completion of this module students will know the following: Basic software maintenance Basic hardware maintenance

3Software Upgrade

The NPU holds the following versions Two 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 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

4Software Upgrade

Step I : file version is transferred to the NPU

8Software 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 e.gping 10.10.10.1

Download the file to the NPU (DATA or MGMT port)

Downloading The File to The NPU

In the command prompt enter the following command:tftp -i PUT e.gtftp -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.gTransfer 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

9Software 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 versionThe 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 mainAt the next boot the unit marks the shadow version as main

Loading The New File

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

10Configuration 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/BST 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

General

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 and

used licenses, CPEs with allocated licenses (local or permanent), CPEs with grace or temporary grace licenses and CPEs for which grace license expired -BSLicense_.res

11Configuration Backup (NPU)

If a backup file already exists in the NPU/BST, 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 edited

General

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

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

12Configuration Backup (NPU)

Verify that IP connectivity is working properly by pinging the NPU (DATA or MGMT port) In the command prompt enter the following command:

ping e.gping 10.10.10.1

Create a backup file Using the monitoring program

Creating a Backup File

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 GET 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

13Configuration Backup (NPU)

Transferring the backup file to an NPU In the command prompt enter the following command:

tftp -i PUT e.gtftp -i 10.10.10.1 PUT c:\NPU_Backup\backup.res

The transfer operation has completed when the following message appears:

Loading a Backup File To an NPU

message appears:"Transfer successful: XXXXXX bytes in YY seconds, ZZZZZZ bytes/s"e.gTransfer successful: 2598936 bytes in 13 seconds, 199918 bytes/s

For the changes to take effect, reset the NPU Using the monitoring program

14Configuration 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

General

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

15Configuration Backup (SU)

Connect to the SU In the command prompt enter the following command:

Telnet e.gtelnet 192.168.254.251\

Create a backup file Using the monitoring program

Creating a Backup File

Configure the TFTP server IP address Set a name for the uploaded a configuration file Verify that the TFTP application is running

Start the upload process "Are You Sure? " message appears Confirm the operation

16Configuration Backup (SU)

Connect to the SU In the command prompt enter the following command:

Telnet e.gtelnet 192.168.254.251

Transferring the backup file to an SU Using the monitoring program Configure the TFTP server IP address

Loading a Backup File To an SU ODU

Configure the TFTP server IP address Set a name of the downloaded configuration file Verify that the TFTP application is running Start the upload process "Are You Sure? " message appears Confirm the operation

For the changes to take effect, reset the SU Using the monitoring program

17Corrective Maintenance

The corrective maintenance is performed upon replacing one of the following units: Any card (PIU, PSU, AU or NPU) from the modular base station
