Network Interface Controllers
NOTE:
To ensure EMI product regulation compliance, the system must be used with shielded
LAN cables.
The I/O board inclu des Intel® 82546
supports the following features:
Two channels of 10Base-T, 100Base-TX, and 1000BASE-T networks.

Sys tem Board Management Controller (BMC)
S erv er management is concentrated in the System Board Management Controller (BMC). The BMC and associated circuitry
ar powered from a 5Vdc standby voltage, which remains active when system power is switched off, but the ac power source is e
st ill on and connected.
The BMC supports the DianaScope (optional), which allows remote server
S ee Chapter 6 or online document in the EXPRESSBUILDER CD-ROM for DianaScope.
O ne major function of the BMC is to autonomously monitor system management events, and log their occurrence in the
n on-volatile System Event Log
o r chassis intrusion. To enable accurate monitoring, the BMC maintains the non-volatile Sensor Data Record (SDR), from
w hich sensor information can be retrieved. The BMC provides an ISA host interface to SDR sensor information, so that
so ftware running on the server can poll and retrieve the server's current status.
T he BMC performs the following:
Monitors server board temperature and voltage
Monitors processor presence and controls Fault Resilient Boot (FRB)
Detects and indicates fan failure
Manages the SEL interface
Manages the SDR Repository interface
