CMC ModuleFigure 12. CMC Module Features1 Ethernet connector Gb1 2 Ethernet connector STK ("stack") - used for daisy-chaining CMCs in separate enclosures3 link indicator 4 activity indicator5 DB-9 serial connector for local configuration 6 optional secondary CMC (CMC 2)7 optional iKVM module 8 primary CMC (CMC 1)9 blue status/identification indicator 10 power indicatorCMC Module FeaturesThe CMC provides the following multiple systems management functions for your modular server:• Enclosure-level real-time automatic power and thermal management.– Monitors system power requirements and supports the optional Dynamic Power Supply Engagement(DPSE) mode. The DPSE mode improves power efficiency by allowing the CMC to dynamically placepower supplies in standby mode, depending on the load and redundancy requirements.– Reports real-time power consumption, which includes logging high and low points with a time stamp.– Supports setting an optional enclosure Maximum Power Limit, which either alerts or takes actions, suchas throttling server modules and/or preventing the power up of new blades to keep the enclosure underthe defined maximum power limit.– Monitors and automatically controls cooling fans based on actual ambient and internal temperaturemeasurements.19
