Dust or chemical contamination at the endface of a fiber optic LC connector or transceiver module impedes signaling. Dell engineering teams have verified cases in which a fully functional port appears to be a bad port because dirty optical connectors manifest as a port failing loop testing with acceptable power measurement levels. Cable connectors should be cleaned and when stored must be protected from dust particle or chemical contamination.

How to Create a Port Channel Link Aggregation Group (LAG) on Dell Networking OS9 and Legacy Force10 switches

This article outlines how to configure basic logging on a Dell switch running OS9.

This is a general guide on how to get the Service Tag from dell switches (OS6, OS9, OS10, or SONiC).

The issue is about new routes are not being installed in the Broadcom hardware on Dell S5248F switches. OS10 can learn new routes, but it is not able to install them in the Broadcom hardware tables. This issue affects all platforms and all OS10 versions, but may be mitigated using switch's configuration or different platforms where the tables are larger than S5200.

As a part of the deployment guidance for Dell EMC Storage Spaces Direct Ready Nodes, for infrastructures that use RoCE v2 for RDMA using Mellanox CX4 LX adapters, we recommend disabling DCBX willing globally in the host OS and setting network adapter DCBXMode to Host in charge.

Troubleshooting the Switch Fabric Module

This article explains how to verify the checksum of the firmware image downloaded into the DELL Networking OS10 switch.

This guide provides instructions on how to configure management networks for accessing networked devices using console servers, Ethernet out-of-band, and Ethernet in-band. Large production networks can span across multiple rooms, buildings, or cities, and contain dozens or hundreds of network switches. Using a management network separate from the production network is often desired to configure and manage these environments. There are three types of management networks that are discussed in this guide, each offering its benefits. Network administrators may use one or more methods to configure, test, and manage their setups.

The purpose of this guide is to provide general guidelines for troubleshoot layer 1 connectivity issues when using transceivers in Ethernet switches.
