4.7.6Using the Update Firmware Command

You can upgrade the operating software of the SmartSwitch 9A100 while the switch is running its current software. This procedure is known as a hot upgrade and is accomplished by the update firmware command.

When the 9A100 switch is started (or rebooted), it copies its operating software 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 software image. While the upgrade is occurring, the switch continues to run its copy in program memory. When the switch is rebooted, the new software image residing in flash RAM is copied into system memory and then run.

To use the hot upgrade feature, the SmartSwitch 9A100 must have network access to an end station running TFTP server software. The SmartSwitch 9A100 operating software 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:

SmartSwitch # update firmware

ServerIP()

: 214.95.77.240

Path()

: luxor/server.ima

You are updating the code image in the flash.

Erasing Flash.

Using TFTP to get and program bootfile luxor/server.ima from 204.95.77.240. 2785K (2852012 bytes) received.

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 9A100 switch. In its current state, the operating software normally stored in flash RAM is erased. The switch is functioning only because it is running the image of the operating software that resides in volatile system memory.

If possible, determine why the update firmware command failed. Common causes for failure are:

•Incorrect path and file names

•Improper permission settings on the directory containing the upgrade software

•SmartSwitch 9A100 is not physically connected to the network

•SmartSwitch 9A100 cannot reach the TFTP server’s subnet
