Power Supply Redundancy
Along with the addition of extra outlet availability, a second Power Distribution Unit coupled
with a second Uninterruptible Power System will create a redundant power supply to improve
reliability. Simply, install a second UPS into the rack environment to ensure enhanced power
protection and connect each PDU to their own individual UPS. In this configuration, if one UPS
goes down, a second power supply remains to protect mission critical devices in case of power
emergency of either electrical source.
IMPORTANT:
The 30A High Voltage Power Distribution Unit is not designed to connect to an
Uninterruptible Power System.
