DELL Jx399 750W Redundant Power Supply for PowerEdge 2950

Dell Jx399 750W redundant PSU for PowerEdge 2950

The Dell Jx399 is a 750 watt redundant power supply module built for the PowerEdge 2950 server. It delivers hot-swap replacement capability to keep the system running during a module failure. This unit suits administrators maintaining existing 2950 deployments. It is not for buyers who need a higher wattage unit or a different form factor.

Sustained load behaviour

Under continuous load the redundant design shares current between modules so each runs below its maximum rating. This reduces thermal stress on internal components during extended operation. The hot-plug architecture allows a failed module to be swapped without powering down the chassis. It does not suit environments that require a single non-redundant supply.
