Users Guide

This option implies that iDRAC's dedicated network port routes its traffic separately from the server's LOM or NIC ports.

About managing network traffic, the Dedicated option allows iDRAC to be assigned an IP address from the same subnet or

different subnet in comparison to the IP addresses assigned to the Host LOM or NICs.

NOTE: In blade servers, the Dedicated option is displayed as Chassis (Dedicated).

• LOM1

• LOM2

• LOM3

• LOM4

NOTE: In the case of rack and tower servers, two LOM options (LOM1 and LOM2) or all four LOM options are

available depending on the server model. In blade servers with two NDC ports, two LOM options (LOM1 and LOM2)

are available and on server with four NDC ports, all four LOM options are available.

NOTE: Shared LOM is not supported on the following bNDCs if they are used in a full — height server with two

NDCs because they do not support hardware arbitration:

• Intel 2P X520–k bNDC 10 G

• Emulex OCM14102–N6–D bNDC 10 Gb

• Emulex OCm14102-U4-D bNDC 10 Gb

• Emulex OCm14102-U2-D bNDC 10 Gb

• QLogic QMD8262–k DP bNDC 10 G

3. From the Failover Network drop-down menu, select one of the remaining LOMs. If a network fails, the traffic is routed

through the failover network.

For example, to route the iDRAC network traffic through LOM2 when LOM1 is down, select LOM1 for NIC Selection and

LOM2 for Failover Network.

NOTE: If you have selected Dedicated in NIC Selection drop-down menu, the option is grayed-out.

NOTE: Failover is not supported on shared LOM for the following Emulex rNDCs and bNDCs:

• Emulex OCM14104-UX-D rNDC 10 Gbx

• Emulex OCM14104-U1-D rNDC 10 Gb

• Emulex OCM14104-N1-D rNDC 10 Gb

• Emulex OCM14104B-N1-D rNDC 10 Gb

• Emulex OCM14102-U2-D bNDC 10 Gb

• Emulex OCM14102-U4-D bNDC 10 Gb

• Emulex OCM14102-N6-D bNDC 10 Gb

NOTE: On Dell PowerEdge FM120x4 and FX2 servers, Failover Network is not supported for the chassis sled

configurations. For more information about the chassis sled configurations, see the Chassis Management Controller

(CMC) User’s Guide available at dell.com/idracmanuals.

NOTE: On PowerEdge FM120x4 servers, while configuring the Enhanced Network Adapter Isolation, ensure that

LOM2 is disabled on the host system and is not selected for iDRAC NIC. For more information about the chassis

sled configurations, see the Chassis Management Controller (CMC) User’s Guide available at

dell.com/

idracmanuals.

4. Under Auto Negotiation, select On if iDRAC must automatically set the duplex mode and network speed. This option is

available only for dedicated mode. If enabled, iDRAC sets the network speed to 10, 100, or 1000 Mbps based on the network

speed.

5. Under Network Speed, select either 10 Mbps or 100 Mbps.

NOTE: You cannot manually set the Network Speed to 1000 Mbps. This option is available only if Auto Negotiation

option is enabled.

6. Under Duplex Mode, select Half Duplex or Full Duplex option.

NOTE: If you enable Auto Negotiation, this option is grayed-out.
