PowerEdge M1000e Technical Guide 65
The Integrated Dell Remote Access Controller (iDRAC) on each server module is connected to the
CMC through dedicated, fully redundant 100 Mbps Ethernet connections wired through the midplane
to a dedicated 24‐port Ethernet switch on the CMC, and exposed to the outside world through the
CMC’s external Management Ethernet interface (10/100/1000M). This connection is distinct from the
three redundant data Fabrics A, B and C. Unlike previous generations of Dell server modules, the
iDRAC’s connectivity is independent of, and in addition to, the onboard GbE LOMs on the server
module. Each server module’s iDRAC has its own IP address and can be accessed, if security settings
allow, directly through a supported browser, telnet, SSH, or IPMI client on the management station.
