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.

System management integration

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.
