4.7.6Using the Update Firmware Command

You can upgrade the operating software of the SmartCell 6A000 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 6A000 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 SmartCell 6A000 must have network access to an end station running TFTP server software. The SmartCell 6A000 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:

SmartCell ZX # 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.

SmartCell ZX #

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 SmartCell 6A000 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

SmartCell 6A000 is not physically connected to the network

SmartCell 6A000 cannot reach the TFTP server’s subnet
