Server Management Summary

The server management system features a Board Management Controller (BMC), which

autonomously monitors server status and provides the interface to server management control

functions. This controller is responsible for controlling system power, resets, monitoring voltages,

temperatures, fans, and communicating with secondary controllers on its Intelligent Platform

Management Bus (IPMB).

Detailed server management tool information and supported operating system information is

contained in the Intel Server Control Installation (ISC) Guide For the cc2300 & cc3300 Carrier

Grade Server. ISC is a server management tool that provides real time monitoring and alerting for

server hardware, emergency remote management and remote server setup.

The functions of each controller are summarized in the following sections.

Board Management Controller (BMC)

The BMC on the server board provides server management monitoring capabilities. Associated

with the BMC is a flash memory that holds the operational code, sensor data records (SDR), and

system event log (SEL). A serial EEPROM holds the BMC configuration defaults and field

replaceable unit (FRU) information. The BMC supports the following:

• Server board voltage monitoring

• Fan failure detection

• Fan speed control

• Processor voltage monitoring

• Processor presence detection

• Processor internal error (IERR) monitoring

• Fault resilient booting (FRB)

• Processor disable control

• Watchdog timer

• Periodic system management interrupt (SMI) timer

• I

C master controller for the Intelligent Platform Management Bus (IPMB)

• Three private I

C management bus interfaces

• Server management software (SMS) and server management mode (SMM) IPMB message

receiver

• Event message receiver

• System event log (SEL) management and access

• Sensor data record (SDR) repository management and access

• Processor nonmaskable interrupt (NMI) monitoring

• Processor SMI monitoring

• Time-stamp clock

• Secure mode

• Software front panel NMI generation
