Downloading Software

45

■You have loaded the boot image and the operational load image in the file server directory, usually named “tftp” or “tftpboot”, from the Software CD-ROM or from the 3Com Web site at the following URL:

http://support.3com.com/infodeli/swlib/index.htm

■The management modules (EME and EMC) that are installed in your chassis are running the compatible software release before you can attempt a module download. To determine which software release is running on a management module, enter:

show module <slot>.all verbose

Where <slot> is the slot location of the module.

To download software Release 3.0:

1From your TFTP file server, download the software to the appropriate switch fabric module or interface module.

At the system prompt, enter the following command:

download module <slot>.1 all_image <server address>

<filename>

Where <slot> is the slot number of the module, <server address> is the IP address of the TFTP server archive where the software image resides, and <filename> is the name of the file that contains all of the appropriate software images for the particular module to which you are downloading.

This filename has the extension .all. The filename may include a directory path to the directory within the file server if this directory is not the file server default directory.

For downloads to take effect, you must reset the modules. Repeat step 1 for all modules in the chassis and proceed to step 2, or enter the command reset module <slot>.1 cold after each module is updated. Where <slot> is the slot number of the module to which you downloaded software.

2At the system prompt, enter the following command:

reset module all cold

Doing this resets all the modules and loads the software that you downloaded from the EME to those modules.
