PowerEdge M1000e Technical Guide 29
The following power-supply combinations are not allowed in the M1000e chassis:
• 2360W + 1350W
• 2700W + 1350W
5.2.4 Chassis Behavior When Powering Up Power Supplies
For information on M1000e chassis behavior when powering up the power supplies, see the Power
Management chapter in the Dell Chassis Management Controller Firmware Version x.x User’s Guide
on Support.Dell.com/Manuals.

For incompatible items, the system allows the AC power to provide 12V standby power, and the AC
good light displays as solid green. This does not allow the power supply to provide 12V main power
and does not allow the power supply to contribute power to the chassis.
5.2.5.1 Behavior of 2700W Power Supply
The CMC must be upgraded to 3.0 for 2700W power supplies to contribute power to the chassis.
5.2.5.2 Behavior of 1350W Power Supply
The CMC must be upgraded to 3.0 for the 1350W to contribute power to the chassis.
Upon first chassis boot up or CMC upgrade to version 3.0 the user must acknowledge 110VAC is
intended to be used. This acknowledgement can happen in the CMC GUI or through the command
line interface (CLI).
5.2.5.3 Behavior of 2700W + 2360W Power Supplies
Mixing 2700W and 2360W power supplies is allowed, but the CMC must be upgraded to 3.0 for the
2700W power supply to contribute power to the chassis. When mixing different capacities, the CMC
adjusts the redundancy algorithm to accommodate the different capacities.
5.2.5.3.1 Grid Redundancy
For grid redundancy, if slots 1–3 and slots 4–6 are not able to provide the same amount of power
capacity, the CMC places the slots with the high capacity into standby.
5.2.5.3.2 Power Supply Redundancy
For power-supply redundancy, the power supply with the highest capacity is placed into redundancy.
