Upgrading software
You can use the CLI or Boot menu to upgrade software. This chapter only describes upgrading software
from the CLI.
Upgrading software includes upgrading the BootWare (called "bootrom" in the CLI) and system
software. Each time the device is powered on, it runs the BootWare image to initialize hardware and
display hardware information, and then runs the system software image (called the "boot file" in
software code) so you can access the software features, as shown in Figure 48.
