Configuring Redundant Hardware
All three switches (layer 2 and layer 3 models) provide a redundant
backplane to ensure that should a supervisor module or a fabric
element fail, it will continue to route data properly. The redundant
components are available as separate options.
When the redundant controller and element are installed, the
backplane consists of the following parts (Figure7-1):
■ One Primary Controller
■ One Redundant Controller
■ Six Primary elements
■ One Redundant element
