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 administrator 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 ASpeed AST2400/AST2500 BMC Controller will connect the PCH to other onboard components, providing remote network interface via serial links. With the AST2400/AST2500 controller and the IPMI firmware 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.
