8.1.6 Using the Update Firmware Command
You can upgrade the operating firmware of the SmartSwitch 6500 while the switch is running its current firmware.
This procedure is known as a hot upgrade and is accomplished by the
update firmware
command.
When the SmartSwitch 6500 is started (or rebooted), it copies its operating firmware from flash RAM to the CPU’s
program memory. When a hot upgrade is performed, the image in flash RAM is erased and replaced with the new
firmware image. While the upgrade is occurring, the switch continues to run its copy in program memory. When the
switch is rebooted, the new firmware image residing in flash RAM is copied into system memory and then run.
To use the hot upgrade feature, the SmartSwitch 6500 must have network access to an end station running TFTP server
software. The SmartSwitch 6500 operating firmware file must reside within the directory specified by the TFTP server
software. Often, this directory is /tftpboot. However, it may be different with your TFTP server software.
The following is an example of a hot upgrade:
Smart6500 # update firmware
ServerIP() : 206.61.237.127
< IP address of TFTP server
Path(public/Smart6500.ima) : builds/luxor2/server.ima
< Path and name of file to download
You are updating the code image in the flash.
Are you sure this is what you want to do?
Confirm(y/n)?:y

Flash update succeeded.
You will have to reboot for the new image to take effect.

Notice that the
update firmware
command does not use Bootp to find the TFTP server. Instead, the
update firmware
command requires that you specify the IP address of the TFTP server, the path to the image file, and the file name.
Unsuccessful Update
If the
update firmware
command fails, DO NOT turn off or attempt to reboot your SmartSwitch 6500 switch. In its
current state, the operating firmware normally stored in flash RAM is erased. The switch is functioning only because
it is running the image of the operating firmware that resides in volatile system memory.
If possible, determine why the
update firmware
command failed. Possible causes are:
