Cause

Unity XT 480/680 supports 2 types of power supply models:ATLAS (220V): PN: 071-000-750-01 Hi-LinePOSEIDON (110V): PN: 071-000-760-03 Low-LineIf the Unity Power Supply is ATLAS (220V), a hi-line power supply, it does not support low line AC voltage such as from a wall power outlet (110V) will cause the alert. Conversely, if the Unity PS is POSEIDON (110V), a low-line power supply, it does not support high line AC voltage (220V) and will cause the alert.

Resolution

To address the issue: Confirm the input voltage as 110V Low Line) or 220V (Hi-Line)Confirm the Power Supply as POSEIDON (110V) or ATLAS (220V) If Input Voltage is in 220 Voltage range and Power Supply is 110V (POSEIDON): change the AC input from 220V to 110V, or replace the Power Supply model from POSEIDON (110V) to ATLAS (220V).If Input Voltage is in the 110 Voltage range and Power Supply is 220V (ATLAS): Change the AC input from 110V to 220V, or replace the Power Supply 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 depends the specific country or region wall plug type.Country Specific Wall-Power Cords 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 15AIMPORTANT 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 on. Insert the original Atlas Power supplies, power on the array and replace each PS one at a time.
