Active Onboard Administrator USB tab
The USB tab only appears if an early version of the c3000 Onboard Administrator board (hardware revision
level A0, B0, X1, or X3) is present.
With such boards, you can only use one USB controller at a time. This screen allows you to select which USB
controller to enable: the one for the USB ports on the KVM module in the rear of the enclosure or the one for
the DVD drive and USB port on the front of the enclosure. Changing the active USB controller resets the Active
Onboard Administrator.
