Configuring the Cajun P550 Switch (Layer 2 & Layer 3)
Configuring Redundant HardwareIn both Layer 2 and Layer 3 models, the Cajun P550 switch provides a redundant backplane to ensure that if a controller or an element fails, the switch 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:
❒One main controller
❒One redundant controller
❒Six switch elements
❒One redundant element

The Cajun P550 switch is equipped with diagnostics to monitor the status of switch controllers and elements. When an element fails, diagnostics run automatically and test the hardware. In the Web Agent, information about a failed controller or element displays in the Switch Fabric Status dialog box.
If the primary controller fails, the redundant controller takes over switch operation until you replace the primary controller. If an element fails, the redundant element takes over the function of the failed element until you replace the element.
The following sections explain how to:
❒Install Redundant Hardware
❒Replace the Primary Controller
❒Replace an Element
