7 Networking and mezzanine cards

The Dell PowerEdge M420 offers balanced, scalable I/O capabilities, including one integrated

PCIe 3.0 capable mezzanine card slot.

With the PowerEdge M420, the process of deploying, updating and monitoring is fast and easy.

System management integration features include:



Pre-boot: Use the Dell Lifecycle Controller graphical user interface (GUI) to set configuration

such as bandwidth allocation or firmware revision level.



Post-boot: Agent-free out-of-band or high-speed in-band connection over LOM through the

Operating System/BMC pass-through feature for sensory information.



Automation of firmware and driver version deployment upon component replacement.



Automatic monitoring of NIC status and notification on SNMP traps.



Local or remote re-configuration of any NIC, physical, or virtual.



PXE boot enabled on LOM for ease-of-use.



Boot from SAN (iSCSI, FCoE) configuration for networking devices through the Lifecycle

Controller GUI.

Expansion connectors

The M420 PCIe expansion connectors provide the following support:



Mezzanine cards: A custom mezzanine connector that connects to an x8 PCIe 3.0 port.

The mezzanine card slot supports Fabric B or Fabric C, depending on the slot in the sleeve

—

where the blade is installed. This card must match the fabric type of the I/O modules installed

in the corresponding I/O module bays. Figure 6 illustrates the interconnectivity matrix and

Figure 7 illustrates interconnectivity examples for Fabric A and Fabrics B and C.



LOM: A custom network controller connector that connects to an x8 PCIe 3.0 slot.

LOM controller through a dedicated one x8 PCIe 2.0 or 3.0 compatible interface

—

Supports the embedded Broadcom 57810S-k 2P 10Gb

—

iDRAC7 shared LOM is not supported, the blade iDRAC has a dedicated 100Mbps link

—



Embedded PERC: A custom PERC + RIPS connector connects to a x4 PCIe slot.
