Chapter 11 Diagnosing a Failed Ethernet Switch Blade
Activation
The Ethernet Switch Blade must transition through a series of states (M0–M4) to become active
in an ATCA shelf. After the Ethernet Switch Blade has reached the M4 state, it will become
active and start the boot process of the OpenArchitect Switch Management environment. If a
failure occurs during the Shelf Manager activation stage, the Ethernet Switch Blade has to be
diagnosed through the ShMM as the OpenArchitect environment is not booted.
Table 11.1 lists the solutions to problems that may occur at the different stages the Ethernet
Switch Blade transitions through to become active and steps that should be taken if it fails during
activation.
