RMM NIC Interface
The Media Independent Interface (MII) is the interface used to connect the Intel
®
Remote
Management Module to the Intel® RMM NIC Interface. This communication path between the
Intel
®
RMM NIC Interface and the Intel
®
RMM is via connectors and is routed on the baseboard.
The Intel® RMM NIC Interface contains a LAN PHY interface chip that is dedicated to the Intel
®
Remote Management Module. This LAN connection is used for all the LAN-based management
features.
The Intel
®
RMM manages all network functions including the following:
 DHCP
 Address Resolution Protocol (ARP)
 Internet Control Message Protocol (ICMP)
 TCP/IP
In addition, the Intel® RMM forwards Intelligent Platform Management Interface (IPMI) UDP/IP
based RMCP and RMCP+ traffic that has been received through the Intel® RMM NIC Interface
to the baseboard BMC. In an Intel® pedestal chassis, the Intel® RMM NIC Interface is mounted
on a PCI* expansion slot cover and can be put in any empty PCI slot in an Intel pedestal
chassis.
Note: The Intel® RMM NIC Interface does not actually occupy a PCI slot on the server
baseboard. It connects to the chassis in an empty PCI expansion slot.
