Redundant Power Configuration
Dual Power Supply Example
A dual power supply configuration can be created by ensuring that two different
branch circuits feed two different Uninterruptible Power Supplies, which in turn
power two PDUs. Figure 3-6 shows a dual power cabling example. This example
shows two LC 2000r units powered by two PDUs and two UPS units. Plugging
each UPS into a different branch circuit ensures dual power supply is maintained.
