46CHAPTER 4: SOFTWARE INSTALLATION

3Confirm that all of the downloads were successful.

To verify that the software releases that you downloaded are correct and that the information in the module’s Auto Emergency Download fields is correct, enter the following command:

show module <slot>.1 verbose

4Update the Emergency Download parameters.

See “Update Emergency Download Parameters”next and complete all the steps.

Update Emergency The Update Emergency Download Parameters procedure allows you to Download change the filename and IP address of the emergency download Parameters parameters that are stored in NVRAM. These values are used if the

operational code on a module that is installed in your chassis becomes corrupted. This code can become corrupted, for example, if a power cycle interrupts an operational code download. After the module resets, the boot code detects that the operational code is corrupted and automatically attempts to download a valid operational code image with the correct filename and IP address. This image is not stored in permanent memory. You must perform a normal download of this image at the EME prompt to download this image into flash.

CAUTION: If you do not perform this normal download, the emergency download repeats each time that the module resets until the maximum number of module resets is reached.

This procedure is only required the first time that you upgrade a module to software Release 3.0. From that point, any time that an operational (.OP) or all (.ALL) image is downloaded to the module, these parameters update automatically.

If the IP address of the file server that contains this file changes, or if the directory where it is located changes, or if the actual filename changes, you must use this procedure to update that information.

1From the EME, connect to the module:

CB9000> connect <slot>.1

The CoreBuilder 9000 menu options screen appears.

2At the prompt, enter module

The Module menu options screen appears.
