This chapter presents the information and procedures necessary to download new software images to the Cisco 6100. With the current release of this feature, you can download new software images to any of the following modules:
System Software Download is the method by which a Cisco 6100 can upgrade the software in each of the modules that support downloading to the module. The software download procedure requires an TFTP server. ViewRunner functions as an TFTP server and will be capable of handling requests for images from a Cisco 6100. However, ViewRunner also will allow the user to specify any IP address and file path for TFTP so that other TFTP servers can handle file transfer.
The software download process is triggered by user menu selection. During the process, the current configuration of the node is saved and is restored upon successful completion. However, as a fail-safe measure, the user should use the configuration save wizard (see "Configuration Save and Restore") to store the current NVRAM configuration for later retrieval in case it becomes necessary.
The software images are grouped by system software release number. ViewRunner maintains a Release Definition File (RDF) which identifies, for a given software release, the software that is compatible with each hardware module/revision. The SC and ViewRunner use the RDF to download the appropriate images required to update the modules in its configuration.
The default destination for the images will be c:\Program Files\Cisco, with each set of images copied to a folder named after that system release. ViewRunner can upgrade to later releases as long as the RDF and corresponding images have been installed.
The following are the procedures to download new software images to the Cisco 6100.
Step 1 Access the update options under the Tools menu on the ViewRunner main menu toolbar.
Select the Tools > View Cisco 6100 Software Image Data option to find out information about the current software images. This will help you determine which images are current and which should be updated.
Step 2 Select Tools > Upgrade Cisco 6100 Software option from the ViewRunner main menu (Figure 13-1) to start the software download wizard. ViewRunner will display a progress bar along with a description of status, while the upgrade is taking place.
Step 3 A wizard starts. It will be a guide throughout the process. The first wizard screen describes the upgrade procedure. Please read each wizard screen carefully to understand various warnings and consequences of continuing the procedure. Select Next to continue.
 | Caution If you have a BOOTP server present, the SC image used will be the one specified in the BOOTP table, not the one restored. |
Step 4 In the second screen, ViewRunner searches for all installed releases (.RDF files). It will present to the user, a list of installed releases for the user to choose from. Select one from the list provided or use the Browse button to find the images you want. When you have selected the image to which you wish to upgrade, press Next to continue.
The default folder for the images is c:\Program Files\Cisco\c6100-2.3.0 where 2.3.0 is the release of the 6100 and where the file name identifies the release of the Cisco 6100 to which you intend to upgrade. The system can be upgraded as long as the release definition file (RDF) and the images have been installed.
Step 5 You will be asked to confirm your choice before continuing.
Step 6 The third wizard screen identifies a default IP Address and IP Path. The user has the choice of changing both. The IP address is the one for the TFTP server. In many cases, this will be the IP address of the PC where ViewRunner is running since ViewRunner for windows functions as a TFTP server. The path is the path to the images to which you want to upgrade.
Select the Local or Remote TFTP Server. The local server is the PC currently executing ViewRunner for Windows. In this case, ViewRunner will use its own TFTP server to transfer the files. If you select the remote server, you must provide the IP address of the remote PC and ViewRunner will use the TFTP server on that remote machine.
Step 7 Depending on your choice of software to download, various information and warning screens may appear. These will present the choice of continuing with the upgrade or canceling.
Step 8 In the case below, images are not available, so your only choice is to cancel the download.
Step 9 You can choose to continue, if an unchanged SC image is acceptable to you.
Step 10 You are informed of any conditions which affect the download. If these conditions are expected, you may choose Next to continue. If they are not expected, press Cancel to stop the process before the download begins.
Step 11 If you choose to continue, the following screen appears informing you that the download procedure is beginning and cannot be interrupted.
Step 12 If the user continues, the following screen displays showing the progress of the download.
If the SC image changed, ViewRunner uses the Save and Restore Configuration to transparently store the NVRAM of the older system. This storage action replaces all configuration items and updates all software images without requiring further user action.
If the SC image does not change, ViewRunner will not execute the Save and Restore Configuration utility. Instead, a dialog will display requiring user input. You have the option of resetting the SC, thereby propagating image updates to all non SC modules. You can reset the SC immediately or at a later time. Choosing to defer the reset until later allows the system to continue operating without a service interruption until an SC Reset triggers completion of the upgrade.
Step 13 See the CPE product procedures for downloading software to those devices.
