Redundant Power/Cooling

Redundant power option is available for the NX5820 and NX5820 K product. Order one component style NX5800-RPW per domain. This style includes only redundant power and contains one ac/dc bulk power supply, one +5 volts dc/dc power supply, and one +3.3 volts dc/dc power supply.

Redundant cooling is included in the basic cabinet and not part of the above style.
