Power supply units
CAUTION:
The PSUs must have the Extended Power Performance (EPP) label. Mixing PSUs (even the PSUs that
have the same power rating) from previous generations of PowerEdge servers is not supported. Mixing PSUs
results in a PSU mismatch condition or failure to turn the system on.
Your system supports two 2400 W AC PSUs.
NOTE: For more information, see the PowerEdge T440 Technical Specs at www.dell.com/poweredgemanuals.
Fault tolerant redundancy
Policy Budgeting
Fault Tolerant Redundancy is a hybrid redundancy mode which uses the power capacity limits of a single Power Supply Unit for
Power Budget Checks, similar to Grid Redundancy, but enforces added performance limiting after redundancy is lost. Previous
generation modular sleds will still work with Fault Tolerant Redundancy enabled, but they treat it identically to Grid Redundancy.
When the maximum potential power needs of installed chassis components exceeds the capacity of a single Power Supply, the
Chassis Management Controller (CMC) will deny power on to further chassis components. The Power Budget Checks for Fault
Tolerant Redundancy ensure that the Shared Infrastructure Chassis will remain operational in the event of maximum potential
workload conditions at the time of an AC Grid or PSU Supply failure. Using the maximum potential is a conservative target that
ensures continued operation across the wide range of potential customer workloads for a given configuration.
Policy philosophy
Similar to Grid Redundancy, Fault Tolerant Redundancy is a conservative redundancy policy that ensures that the Shared
Infrastructure Chassis and all installed components remain operational with no risk of shutdown in the event of an AC Grid or
Power Supply failure even when all installed components are simultaneously running at their worst case power consumption.
New for Fault Tolerant Redundancy is a limit on peak performance that occurs when redundancy is lost. Fault Tolerant
