4.7.3Upgrading Boot Load Software
Two images of the boot load software 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 software.
1.Set up the TFTP/Bootp server software on a workstation.
2.Connect both the TFTP/Bootp server and the SmartCell 6A000 to your Ethernet network. Make sure that the TFTP/Bootp server can be reached by the SmartCell 6A000 Ethernet interface.
3.Connect a dumb terminal (or PC running terminal emulation software) to the SmartCell 6A000 Terminal port.
4.Copy the SmartCell 6A000 boot load software image into the appropriate location on the TFTP/Bootp server. (In this example, the software is copied to c:\tftpboot\images\boot.ima.)
