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 address the issue: Change the AC input from 110V to 220V  or  replace the PS model from ATLAS to POSEIDON

The Poseidon power supply is only used for Low Line power for the Unity XT 480(F) and Unity XT 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 using the DOC-394778 link below.  
The connector on the other end of the cable is dependent on the specific country wall plug type.


Country Specific Wall-Power Cords:  https://inside.dell.com/docs/DOC-394778

NOTE:  Order these Country Specific Cords directly from MyQuotes and provide the Dell/EMC Model number.  

EXAMPLE:     The United States uses Dell/EMC Model number: 
C19-PWR-12   Part Number: 038-004-848   
Description:    C19 PWR CORD W/ NEMA 5-15P PLUG, 125V 15A

IMPORTANT REPLACEMENT NOTE: The Power Supplies (PSs) must 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 the array is powered off and the PSs are replaced - the array may not power up.  Insert the original Atlas Power supplies, power up the array and replace each PS one at a time.
Notes

The different cable types are available in the ordering path when you select Low Line Power. 
By default when ordering a new system for Low Line power you will be asked for the Country Specific Wall Cord..
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.

Power specifications per Unity model
Model                     High line      Low line
Unity 480/480F      1800 W        1450 W
Unity 680/680F      1800 W        1450 W
Unity 880/880F      1800 W        1800 W (Step-up transformer required)

ATLAS Specification: GEN2 CFF 1800W HL 1050W LL PSU AC
POSEIDON Specification: GEN2 CFF 1450W LL 2100W HL AC DC PSU AC

Additional notes:  
Atlas is to be used in all cases where the array is being  installed in a cabinet running 220vAC;  A sales order with High line power selected and using standard c13/c14 power cords.
Poseidon will be ordered to run 110vAC along with the use of a country specific wall outlet:   A sales order with a Low line power selected ...you will be asked to select a specific country wall outlet cable. 

120vAC PDU is being used:  
In rare cases where a customer is using a 120V PDU, you may need to special order a C19 to C20 or C19 to C14 power cable if the PDU uses a rack type C19 or C13 connections. It may not have a typical wall outlet connection.  These cables would only be needed if the customers 120vAC PDU has rack type C19 or C13 connections

Special Order:   C20 to C19 cable:

038-004-807 - C20 to C19 1m 14AWG black
038-004-808 - C20 to C19 1m 14AWG gray

** The above part is not in the L-EMC database and would need to be ordered separately.
