42 PowerEdge M1000e Technical Guide
When starting a chassis from cold boot with a mix of 110VAC and 220VAC power supplies, the CMC
will power up the first-detected power supply in slots 1-3 and slots 4-6 and will choose the lead
voltage reference. All power supplies must match the lead voltage reference for the system to allow
the power supplies to be powered on.
If switching from 220VAC to 110VAC or vice versa, you will need to remove all power from the
chassis and power the chassis with the new voltage line.
Behavior of AC supplies with DC supplies
You cannot combine 2360W or 2700W AC power supplies with 2700W DC power supplies to power
the M1000e chassis.
If you insert a DC power supply into a chassis running on AC power, the system will not allow
the DC power supply to provide capacity to the system. The AC good light will illuminate, but the
DC good light will not.
If you insert an AC power supply into a chassis running on DC power, the system will not allow
the the AC power supply to provide capacity to the system. The AC good light will illuminate, but
the DC good light will not.
If you wish to switch from AC power supplies to DC power supplies or vice versa, you must to
remove all power from the chassis and power the chassis with the new voltage line.
Recommended number of servers
This section provides the suggested maximum number of blade servers to run under each power
supply configuration.
Quarter-height blade servers
Table 11 lists the maximum number of recommended quarter-height blade servers per power supply
configuration according to the following server configuration definitions:
Light configuration: 1 x 60W processor, 4GB memory
Medium configuration: 2 x 80W processors, 4GB memory
Heavy configuration: 2 x 95W processors, 192GB memory
