Embedded NIC/LAN on motherboard (LOM)

The PowerEdge C5220 has a single Intel 82580DB dual-port Gigabit Ethernet controller installed on

the system board as an independent Ethernet interface device. From a board perspective, the LOM

refers to this controller. Other features include:



x4/x2/x1 PCIe 2.0 capable interface



Power 2.8W (max) in dual port mode and 4.2W (max) in quad port mode



DMA Coalescing, Smart Power Down (SPD) and Active State Power Management (ASPM)



I/O virtualization



Eight transmit and receive queue pairs per port



Flexible port partitioning



SR-IOV support



Stateless offloads



TCP/UDP IPv4 checksum offloads



IPv6 support for IP/TCP and IP/UDP receive checksum offload



Tx TCP segmentation offload



Low latency interrupts



Remote boot



PXE 2.1 remote boot



iSCSI boot



Wake-up support



Wake-on-LAN (WOL)



ACPI specification v2.0c



Magic Packet wake-up enable with unique MAC address



IPv4 and IPv6 support



Supports teaming

I/O slots

The PowerEdge C5220 supports one x8 PCIe 2.0 mezzanine card slot on only the 8-sled version.



LSI 2008 SAS controller



Intel dual-port 1GbE NIC



Intel dual port 10GbE NIC

These cards require a linking board installation. The Intel mezzanine cards use the same linking

boards and the LSI SAS mezzanine card uses a unique linking board.

The 12-sled version does not support PCIe slots because of space and thermal constraints.
