Dell Force10 S25N-S50N Setup Guide

Basic Layer 2 Setup and Buffer Tuning of the

S25P for Storage Environments

Introduction

This document is intended for the users of S-Series S25P switches running FTOS 7.8.1.0 and configured
for use in a storage environment. This document describes:

• Using the console port to enable all ports on the switch for Layer 2 switching

• Verifying that the installed FTOS software is FTOS 7.8.1.0

• Setting up passwords for managing the switch. For details on management, see the Management
chapter in the FTOS Configuration Guide for the S-Series and the Control and Monitoring chapter in
the FTOS Command Reference for the S-Series.

• Optimizing the buffer for use in pure storage environments

This document does not cover:

• Installing optional modules. For installation details, see the document Installing S25P Systems. For a
configuration example, see Figure 7 on page 6 here.

• Adding the switch to an S-Series stack. For stacking configuration details, see the Stacking chapters in
the Configuration Guide and the Command Reference listed above.

• Layer 3 (IP addressing) configuration. For details, see the Interfaces and IP Addressing chapters in the
Configuration Guide and Interface Commands chapter in the Command Reference listed above.

The full S-Series documentation set is available on the Technical Documentation CD-ROM and from the
Documentation tab of iSupport at the Force10 Networks website:

Step Task

1 Install a straight-through RJ-45 copper cable (a standard Ethernet cable) between your system and the console

port of the S-Series switch. The console port is at the far left of the faceplate.

2 Turn on the switch by connecting it to power (there is no on/off button).

3 After the switch boots up (the status messages stop), press Enter twice to get the EXEC mode prompt. You

should see Force10>, as shown below.

Verifying the Software Release and S-Series Model

Unless you know that your system has already been installed with FTOS 7.8.1.0 or later, verify that the
required version is installed.

In this case, the password was selected to be encrypted, so the result displayed is encrypted. For details on
setting passwords, see the Getting Started chapter in the FTOS Configuration Guide for the S-Series and
the Security chapter in the FTOS Command Reference for the S-Series.
