11.3 I
2
C (Inter-Integrated Circuit)
I
2
C is a simple bi-directional two-wire bus for efficient inter-integrated circuit control. All I
2
C -bus
compatible devices incorporate an on-chip interface that allows them to communicate directly with each
other via the I
2
C-bus. This solves the many interfacing problems encountered when designing digital
control circuits. These I
2
C devices perform communication functions between intelligent control devices
(e.g., microcontrollers), general-purpose circuits (e.g., LCD drivers, remote I/O ports, memories), and
application-oriented circuits.
12 Embedded NICs/LAN on Motherboard (LOM)
12.1 Overview
There is BROADCOM 5716 chip on the PowerEdge R410 motherboard. The 5716 chip is connected to
the IOH via a PCI Express x4 gen2 link. The chip provides a two-gigabit Ethernet port. There are two
RJ-45 connectors with integrated magnetic on the rear of the system. The firmware for the LOM chip
resides in a flash part. The PowerEdge R410 supports Wake-On-LAN (WOL) from either port.
