This document is the latest version of the Intelligent Platform Management Interface specifications. IPMI, v2.0, includes new features such as "Serial Over LAN" (SOL) for redirecting a baseboard serial port over an IPMI LAN session extended and Remote Management Control Protocol+ (RMCP+) that provides enhanced authentication and confidentiality (encryption) capabilities for IPMI LAN sessions. New infrastructure capabilities deliver new standard and OEM payloads over an IPMI session and a new Firmware Firewall capability simplifies command discovery and enables restricting management feature access across different IPMI interfaces to enhance security. Additionally, the SSIF (SMBus System Interface) supports inexpensive, low pin-count management controllers, extended sensor and entity types, and sensor data record capabilities. To help simplify migrating to the new IPMI, v2.0, capabilities, the main additions and changes from the IPMI, v1.5, specifications are highlighted in this version with blue text. Note that using the IPMI Second Generation, v2.0, Specification requires signing a new Adopter's agreement.

IPMI, v1.5, adds remote management access over Serial/Modem and LAN connections, and new capabilities for automatic alerting and recovery. IPMI, v1.5, is a superset of and backward compatible with earlier IPMI, v1.0, specification. It also includes extensions to support other existing and emergent standards. See IPMI, v1.5, white paper overview for brief outline of the features and changes in IPMI, v1.5. The revision 1.1 update of the IPMI, v1.5, specification incorporates important errata and addenda that address issues discovered in the original document, revision 1.0, release of the specification. A companion addenda and errata document (revision 5) separately lists the errata and addenda that have been included.
