Unity XT reported that both power supplies in the systems are not supported:
SP logs (Can be found in the Unity support data collection tar file under spX\EMC\backend\log_shared\EMCSystemLogFile.log -- where spX is the primary SP):
Fbecli logs (Can be found in the Unity support data collection tar file under spX\cmd_outputs\fbecli_exe_ccollectall.txt -- where spX contains the log for that SP):
Currently Unity XT 480/680 supports 2 types of power supply models:
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.
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.
The different cable types are available in the ordering path when you select Low Line Power.
