Ensuring the FN IOM system is in Standalone Mode

To ensure that the FN IOM is in Standalone Mode, use the show system stack-unit 0 iom-mode command.

Dell#show system stack-unit 0 iom-mode

Unit Boot-Mode Next-Boot

------------------------------------------------

0 standalone

If the FN IOM system is not in the Standalone Mode, reset the system to its factory default state. To reset the system, use the restore

factory-defaults stack-unit 0 clear-all command. It brings the system in standalone (precongured) mode and sets all

conguration settings to a known state.

Dell#restore factory-defaults stack-unit 0 clear-all

Proceed with factory settings? Confirm [yes/no]:y

Conguration Examples

Following are the conguration examples for common upstream switches. To establish a functional uplink and bring the network ports on

PowerEdge FC-Series servers up (FC830, FC630, FC430, FC 620, and FC420) use the following steps:

1 Ensure that the FN IOM system is in Standalone Mode.

2 Create a LACP LAG on the upstream top of rack switch.

3 Verify the connection.

By default the network ports on the PowerEdge FC-Series servers installed in the FX2 chassis is down, until the uplink port channel is

operational on the FN IOM system. It is due to an Uplink Failure Detection, by that when upstream connectivity fails; the FN IOM disables

the downstream links.

You can disable the UFD on a precongured FN IOM using the following commands:

Dell#configure

Dell(conf)#uplink-state-group 1

Dell(conf-uplink-state-group-1)#no enable

Dell#show uplink-state-group

Uplink State Group: 1 Status: Disabled, Down

To re-enable UFD, use the following commands:

Dell#configure

Dell(conf)#uplink-state-group 1

Dell(conf-uplink-state-group-1)#enable

Dell#show uplink-state-group

Uplink State Group: 1 Status: Enabled, Up
