7.2.3Upgrading Boot Load firmware
Two images of the boot load firmware reside in flash RAM. The two images are identified as boot load image 0 and boot load image 1. Both boot load images can be upgraded by using a TFTP/Bootp server. However, an upgrade is always written over the boot load image that is not currently running. This insures that if a boot load upgrade fails, there is still one good boot load image to fall back on.
Follow the steps below to upgrade the switch boot load firmware.
1.Set up the TFTP/Bootp server software on a workstation.
2.Connect both the TFTP/Bootp server and the ATM SmartSwitch to your Ethernet network. Make sure that the TFTP/Bootp server can be reached by the ATM SmartSwitch Ethernet interface.
3.Connect a dumb terminal (or PC running terminal emulation software) to the ATM SmartSwitch Terminal port.
4.Copy the ATM SmartSwitch boot load firmware image into the appropriate location on the TFTP/Bootp server. (In this example, the firmware is copied to c:\tftpboot\images\boot.ima.)
5.Set up the TFTP/Bootp server tables (or equivalent file) with:
-ATM SmartSwitch MAC address
-IP address of the ATM SmartSwitch Ethernet interface
-path to the boot image file on the TFTP/Bootp server
6.From the terminal connection, enter the reboot command.
7.When the following message appears,
“Press any key to exit to bootline prompt.”
stop the countdown by pressing any key. The bootline prompt (=>) appears on the terminal screen.
8.Enter the df B command. The ATM SmartSwitch contacts the TFTP/Bootp server and downloads the file into the boot load image location that corresponds to the boot load image not currently running. For example, if boot load image 0 is running, df B downloads the file into boot load image 1, leaving boot load image 0 untouched.
