Introduction

This deployment guide covers a step-by-step procedure to minimize network downtime when upgrading from
Dell 10 Gigabit Ethernet (10GbE) Pass-through Modules (PTMs) to PowerEdge FN410S Input/Output
Modules (IOMs) in a PowerEdge FX2 chassis.
When upgrading, all servers in the chassis may remain up throughout the process. In the scenario covered in
this guide, the PTMs are hot-swapped one at a time so that no more than half of the server network ports are
down at any point in the upgrade.
Upgrading from PTMs to FN410S IOMs provides the following benefits:

Adds multilayer switching capability to the chassis

Adds redundancy to links going to the top-of-rack (ToR) switch

Optimizes east-west traffic by allowing server-to-server communication within the chassis

Can significantly reduce cabling at the back of the chassis

Additional configuration is not required on the FN410S for many common deployments
Note: If FX2 server network adapters are configured such that a single LACP NIC team spans both PTMs,
and therefore will span both FN410S IOMs upon replacement, the FN410S IOMs will need to be configured
as Virtual Link Trunking (VLT) peers. This will bring all network ports in the FX2 chassis down during
configuration. Use the

Before upgrading

Dell EMC recommends reviewing the
before upgrading to FN410S IOMs. The Easy Deployment Guide covers basic FN IOM tasks such as the
following:

Resetting to factory defaults

Establishing a remote or serial connection to the management interface

Disabling and re-enabling Uplink Failure Detection (UFD)
