SmartSwitch ATM User Guide 7-17 FIRMWARE UPGRADES ANDBOOTLINE COMMANDS7.1 UPDATE FIRMWARE COMMANDSYou can upgrade the operating firmware of an ATM SmartSwitch while the switch is running its current firmware. Thisprocedure is known as a hot upgrade and is accomplished by the update firmware command.When an ATM SmartSwitch is started (or rebooted), it copies its operating firmware from flash RAM to the CPU’sprogram memory. When a hot upgrade is performed, the image in flash RAM is erased and replaced with the newfirmware image. While the upgrade is occurring, the switch continues to run its copy in program memory. When theswitch 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 ATM SmartSwitch must have network access to an end station running TFTP serversoftware. The ATM SmartSwitch operating firmware file must reside within the directory specified by the TFTP serversoftware. 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 firmwareServerIP() : 206.61.237.127 — IP address of TFTP serverPath(public/server.ima) : builds/luxor2/server.ima — Path and name of file to downloadYou are updating the code image in the flash.Are you sure this is what you want to do?Confirm(y/n)?:y — Specify Yes to start download processVerifying bootfile builds/luxor2/server.ima on 206.61.237.127...passed.Erasing Flash.Using TFTP to get and program bootfile builds/luxor2/server.ima from 206.61.237.127.4904K (5021760 bytes) received.Flash update succeeded.You will have to reboot for the new image to take effect.SmartSwitch #Notice that the update firmware command does not use Bootp to find the TFTP server. Instead, the update firmwarecommand requires that you specify the IP address of the TFTP server, the path to the image file, and the file name.Unsuccessful UpdateIf the update firmware command fails, DO NOT turn off or attempt to reboot your ATM SmartSwitch. In its currentstate, the operating firmware normally stored in flash RAM is erased. The switch is functioning only because it isrunning the image of the operating firmware that resides in volatile system memory.
