Cause:
Currently Unity XT 480/680 supports 2 types of power supply models:
ATLAS: PN: 071-000-750-01
POSEIDON: PN: 071-000-760-03
If the Unity PS is ATLAS, a hi-line power supply, it does not support low line AC voltage such as from a wall power outlet (110V) and will cause the alert.
Resolution:
To fix the issue:
- Change the AC input from 110V to 220V
or
- Replace the PS model from ATLAS to POSEIDON
NOTE: Power Supplies may be replaced while the array is running. Replace one power supply at a time. Alerts will be generated during the swap. Alerts like “Power Supply Intermix” can be ignored/acknowledged.
If you are connecting the Poseidon Power supply to a wall outlet, order the correct cable to go from the power supply to a wall outlet using the DOC-394778 link below.
The Poseidon power supply is only used for Low Line power for the Unity 480(F) and Unity 680(F) where supply voltages to the storage array are in the 100-120V range. To connect the power supply to a wall outlet, select the C19 cable with the specific countries wall outlet connector. The connector on the other end of the cable is dependent on the specific country wall plug type.
More details on which cable part number to use in each country can be found here:
Country Specific Wall-Power Cords: https://inside.dell.com/docs/DOC-394778
NOTE: Please order these Country Specific Cords directly from MyQuotes and provide the EMC Model number.
EXAMPLE: The United States uses EMC Model number: C19-PWR-12 Part Number: 038-004-848
Description: C19 PWR CORD W/ NEMA 5-15P PLUG, 125V 15A
Notes:
The different cable types are available in the ordering path and are added by default when ordering a new system for Low Line power.
They are also available in the “Add-on Hardware” section in both the new and upgrade MyQuotes ordering paths.
According to Unity XT hardware guide, the power requirements are below. When using low line power input, ATLAS PS only supplies 1050W which doesn’t meet the 1450W power requirement to DPE but POSEIDON fully supplies the capacity.
