About Your System 49
The CMC provides multiple systems management functions for your
modular server:
• Enclosure-level real-time automatic power and thermal management.
– The CMC monitors system power requirements and supports the
optional Dynamic Power Supply Engagement mode so that the CMC
can enable or place power supplies in standby dynamically depending
on load and redundancy requirements to improve power efficiency.
– The CMC reports real-time power consumption, which includes
logging high and low points with a time stamp.
