Cabling Your Cluster Hardware NOTE: To configure Dell blade server modules in a Dell™ PowerEdge™ cluster, see the Using Dell Blade Servers in a Dell PowerEdge High Availability Cluster document located on the Dell Support website at support.dell.com/manuals. Cabling the Mouse, Keyboard, and Monitor When installing a cluster configuration in a rack, you must include a switch box to connect the mouse, keyboard, and monitor to the nodes. See the documentation included with your rack for instructions on cabling each node's connections to the switch box. Cabling the Power Supplies Refer to the documentation for each component in your cluster solution to ensure that the specific power requirements are satisfied. The following guidelines are recommended to protect your cluster solution from power-related failures: • For nodes with multiple power supplies, plug each power supply into a separate AC circuit. • Use uninterruptible power supplies (UPS). • For some environments, consider having backup generators and power from separate electrical substations. Figure 2-1, and Figure 2-2 illustrate recommended methods for power cabling for a cluster solution consisting of two PowerEdge systems and two storage systems. To ensure redundancy, the primary power supplies of all the components are grouped onto one or two circuits and the redundant power supplies are grouped onto a different circuit.
