1-3 Introduction to the IPMI Platform
The Intelligent Platform Management Interface (IPMI) provides remote access to
multiple users at different locations for networking. It also allows a system admin-
istrator to monitor system health and manage computer events remotely.
IPMI operates independently from the operating system. When used with an IPMI
Management utility installed on the motherboard, the WPCM450 BMC Controller will
connect the South Bridge to other onboard components, providing remote network
interface via serial links. With the WPCM450 Controller and the IPMI rmware built
in, the Supermicro motherboard allows the user to access, monitor, diagnose, and
manage a remote server via Console Redirection. It also provides remote access to
multiple users from different locations for system maintenance and management.
