Cluster Hardware Cabling

This section provides information on cluster hardware cabling.

Mouse, Keyboard, And Monitor Cabling Information

When installing a cluster configuration in a rack, you must include a switch box to connect the mouse, keyboard, and
monitor to the nodes. For instructions on cabling the connections of each node to the switch box, see the documentation
included with your rack.

Power Supplies Cabling Information

See 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 cluster nodes and storage arrays 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.
The following figures illustrate recommended methods for power cabling a cluster solution consisting of two Dell
PowerEdge systems and one storage array. To ensure redundancy, the primary power supplies of all the components
are grouped into one or two circuits and the redundant power supplies are grouped into a different circuit.
