5.1 Platform Management Overview
The purpose of the hardware platform management system is to monitor, control, and assure proper
operation of AdvancedTCA® boards and other shelf components. The hardware platform management
system watches over the basic health of the system, reports anomalies, and takes corrective action
when needed. The hardware platform management system can retrieve inventory information and
sensor readings as well as receive event reports and failure notifications from boards and other
intelligent FRUs. The hardware platform management system can also perform basic recovery
operations such as reset of managed entities.
The IPMC controller on the aTCA-3710 supports an “intelligent” hardware management system, based
on the Intelligent Platform Management Interface Specification. The hardware management system
provides the ability to manage the power, cooling, and interconnect needs of intelligent devices; to
monitor events; and to log events to a central repository.
5.2 Serial Over LAN (SOL)
Serial Over LAN (SOL) is a remote management feature that allows the IPMC (Smart Fusion A2F500) to
redirect the serial console from the blade via an IPMI session over the network with RMCP+ protocol.
The aTCA-3710 supports SOL on the Base Interface which is powered by the BCM56334 Gigabit
Ethernet Switch. The BCM56334 Gigabit Ethernet Switch is connected to the IPMC (Smart Fusion
A2F500) via the NC-SI interface, which provides remote management capability before the payload
power is authorized. Users can use the SOL feature to transmit/receive serial console message from a
remote site with full console management functionality.
