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 SmartSwitch 9A100. Follow the procedure outlined below:
1.
Set up TFTP/Bootp server software on a workstation.
2.
Connect both the TFTP/Bootp server and the SmartSwitch 9A100 to your Ethernet network. Make
sure that the TFTP/Bootp server can be reached by the SmartSwitch 9A100 Ethernet interface.
3.
Connect a dumb terminal (or PC running terminal emulation software) to the SmartSwitch 9A100
Terminal port.
4.
Copy the SmartSwitch 9A100 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 SmartSwitch 9A100 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 SmartSwitch 9A100 contacts the TFTP/Bootp server and downloads
the operating software into its flash RAM.

SAVING CORE DUMPS
The SmartSwitch 9A100 core dump feature allows you to specify a local Ethernet host where, in the event of a system
failure, the SmartSwitch 9A100 sends a copy of its memory. SmartSwitch 9A100 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.
