4 PowerEdge FX2 - Upgrading from 10GbE Pass-through Modules to FN410S I/O Modules | version 1.01 IntroductionThis deployment guide covers a step-by-step procedure to minimize network downtime when upgrading fromDell 10 Gigabit Ethernet (10GbE) Pass-through Modules (PTMs) to PowerEdge FN410S Input/OutputModules (IOMs) in a PowerEdge FX2 chassis.When upgrading, all servers in the chassis may remain up throughout the process. In the scenario covered inthis guide, the PTMs are hot-swapped one at a time so that no more than half of the server network ports aredown 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 deploymentsNote: 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 configuredas Virtual Link Trunking (VLT) peers. This will bring all network ports in the FX2 chassis down duringconfiguration. Use the PowerEdge FX2 – FN I/O Module – VLT Deployment Guide for this scenario.1.1 Typographical conventionsThis document uses the following typographical conventions:Monospace text CLI examplesBold monospace text Commands entered at the CLI promptUnderlined monospace text CLI examples that word wrap (text is entered as a single command)Italic monospace text Variables in CLI examples1.2 Before upgradingDell EMC recommends reviewing the Dell PowerEdge FN I/O Module (FN IOM) - Easy Deployment Guidebefore upgrading to FN410S IOMs. The Easy Deployment Guide covers basic FN IOM tasks such as thefollowing: Resetting to factory defaults Establishing a remote or serial connection to the management interface Disabling and re-enabling Uplink Failure Detection (UFD)
