Saving Core Dumps | Switch Administration |
If the problem is corrected, enter the update firmware command to continue with the upgrade process. However, if you are unable to correct the problem, use the df (download flash) command and a TFTP/Bootp server to replace the operating software on your SmartCell 6A000. Follow the procedure outlined below:
1.Set up TFTP/Bootp server software on a workstation.
2.Connect both the TFTP/Bootp server and the SmartCell 6A000 to your Ethernet network. Make sure that the TFTP/Bootp server can be reached by the SmartCell 6A000 Ethernet interface.
3.Connect a dumb terminal (or PC running terminal emulation software) to the SmartCell 6A000 Terminal port.
4.Copy the SmartCell 6A000 operating software image into the appropriate location on the TFTP/Bootp server.
5.Set up the TFTP/Bootp server tables (or equivalent file) with the SmartCell 6A000 MAC address and IP address. You may also need to specify the path to the image file to be downloaded.
6.From the terminal connection, enter the reboot command.
7.When the following message appears,
“Press any key to exit to boot load prompt. “
stop the countdown by pressing any key. The boot load prompt (=>) appears on the terminal screen.
8.Enter the df s command. The SmartCell 6A000 contacts the TFTP/Bootp server and downloads the operating software into its flash RAM.

4.8SAVING CORE DUMPS
The SmartCell 6A000 core dump feature allows you to specify a local Ethernet host where, in the event of a system failure, the SmartCell 6A000 sends a copy of its memory. SmartCell 6A000 system memory is saved to two files, one containing CPU memory (core_cpu), the other common memory (core_cmn). These files can then be sent to Cabletron customer support for analysis.
Note To use the core dump feature, the local Ethernet host must be running TFTP server software, and you must have write access to the TFTP directory.
