Specific instructions for updating chassis and component firmware are available in the Sun Blade 6000 Modular System Firmware Update Guide.
The following are general guidelines for updating chassis firmware:
You can upgrade Sun Blade 6000 chassis, server module, and NEM firmware independently.
You should always update server module firmware before updating the CMM firmware.
If a NEM firmware update is required, you should install it before updating CMM firmware.
Caution - Some firmware upgrade procedures remove a component from service. For example, server module ILOM upgrade procedures might shut down the server to perform BIOS upgrades. NEM and storage module firmware upgrades (or hot-swapping) might interrupt I/O connectivity to multiple blades.
