10 Embedded NICs/LAN on Motherboard (LOM)

10.1 Overview

The PowerEdge R210 II includes a Broadcom® 5716C chip embedded on the motherboard. The 5716 chip is connected to the IOH via a PCI Express x4 gen2 link. The 5716 chip provides two 1x Gigabit Ethernet ports with two RJ-45 connectors on the rear of the system. Other details include:

∙The firmware for the LOM chip resides in a flash part

∙The R210 II supports Wake-On-LAN (WOL) from either port

10.2 Features

The Broadcom® 5716C controller-based LOM supports multiple functions over a unified fabric to help manage Ethernet, iSCSI and remote management traffic on each port simultaneously. The LOM provides dual 10/100/1000 Gigabit Ethernet functions, an IEEE 802.3-compliant media access controller (MAC), and a UTP copper physical layer transceiver solution for high-performance network applications. The LOM also supports the following functions:

∙Multiple speed support with dual 10/100/1000-Mbps Ethernet MACs, including half-duplex and full-duplex capability and a dual 10/100/1000 copper PHY

∙PCIe compliance with an x4 PCI Express v2.0- and v1.1-compliant bus interface

∙Diagnostics:

oLink quality indicator LED

oLink speed indicator LED

oBroadcom remote cable management and diagnostics software (Broadcom Advanced Control Suite [BACS])

oLOM continually monitors various channel conditions

∙Power management options

∙Teaming using Broadcom software:

oSupport for virtual LANs (VLANs):
