7 Frequently Asked Questions
What is Max Power Conservation Mode (MPCM) in CMC? How is MPCM associated with Power
Manager actions?
When Maximum Power Conservation Mode is enabled on a chassis, all connected blade servers start
functioning at their minimum power levels, and all subsequent server power allocation requests are denied. In
this mode, the performance of powered on servers may be degraded. Additional servers cannot be powered
on, regardless of the server priority.
Configuring EPR throttle for CMC (PowerEdge M1000e, PowerEdge FX2/FX2s, PowerEdge VRTX) enables
the MPCM mode in chassis.
