The Intelligent Platform Management Interface (IPMI) Specifi cation defi nes a set of
common interfaces to a computer system that provides remote access to multiple
users from different locations for networking. It also allows a system administrator
to monitor system health and to manage the computer events remotely.
IPMI operates independently of the operating system. When used in conjunction with
the IPMIView, an IPMI-compliant management application software loaded into a
PC, the WPCM450 BMC Controller, embedded onto a server board, provides serial
link connections between the South Bridge and other onboard system components,
allowing for network interfacing via remote access. With WPCM450 Controller and
the IPMIView software, the Supermicro motherboard allows an administrator to
access, monitor, diagnose and manage a computer system from a remote site. It
also provides remote access to multiple users from different locations for system
maintenance and management.
