System Management
The ATCA-9305 provides an intelligent hardware management system, as defined in the 
AdvancedTCA Base Specification (PICMG® 3.0). This system implements an Intelligent Plat-
form Management Controller (IPMC) based on the BMR-H8S-AMCc® reference design from 
Pigeon Point Systems. It also has an inter-integrated circuit (I
2
C) controller to support an 
Intelligent Platform Management Bus (IPMB) that routes to the ATCA backplane.
The IPMC implements all the standard Intelligent Platform Management Interface (IPMI) 
commands and provides hardware interfaces for other system management features such 
as Hot Swap control, LED control, power negotiation, and temperature and voltage moni-
toring. The IPMC also supports an EIA-232 interface for serial communications via the Serial 
Interface Protocol Lite (SIPL) IPMI commands.
IPMC OVERVIEW
The basic features for the IPMC implementation include:
• Conformance with AdvancedTCA Base Specification (PICMG® 3.0)
• Geographical addressing according to PICMG® 3.0
• Ability to read and write Field Replaceable Unit (FRU) data 
• Ability to reset IPMC from IPMB 
• Ability to read inlet and outlet airflow temperature sensors
• Ability to read payload voltage/current levels
• Ability to send event messages to a specified receiver
• All sensors generate assertion and/or de-assertion event messages
• Support for fault tolerant HPM.1 firmware upgrades 
• Support for field updates of firmware via IPMB-0 or the payload interface
• Redundant boot bank capability
