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.
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
connections of each node to the switch box.
Cabling the Power Supplies
See the documentation for each component in your cluster solution and
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 into one or two circuits and the redundant power
supplies are grouped into a different circuit.
