1 Introduction
This document illustrates how to configure Dell™ Networking N2000 Series switches for use with
EqualLogic™ PS Series storage using Dell best practices. The recommended configuration uses link
aggregation groups (LAGs) for inter-switch connections.
If you are following the Rapid EqualLogic Configuration steps at
http://en.community.dell.com/techcenter/storage/w/wiki/3615.rapid-equallogic-configuration-portalby-sis.aspx, use sections 1 and 2 from this guide for LAG, or sections 1 and 3 from this guide for stack
configuration.
For more information on EqualLogic SAN design recommendations, see the EqualLogic Configuration
Guide at: http://en.community.dell.com/dell-
groups/dtcmedia/m/mediagallery/19852516/download.aspx.
1.1 Audience
This switch configuration guide describes an optimal configuration following Dell best practices for an
EqualLogic iSCSI SAN and is intended for storage or network administrators and deployment personnel.
1.2 Switch details
The table below provides an overview of the switch configuration.
Table 1 Switch specifications
Note: For proper functionality, the switch must be at the switch firmware version shown in the table
above before proceeding with this configuration. Using previous firmware versions may have
unpredictable results.
The latest firmware updates and documentation can be found at: support.dell.com.

2 Dell recommended switch configuration
These steps show you how to configure two Dell Networking N2000 switches with a Link Aggregation
Group (LAG). The switches are interconnected using the fixed 10GbE SFP+ module on the front and the
LAG is configured for Dynamic Link Aggregation Control Protocol (LACP).
2.1 Hardware configuration
1. Power on the two switches.
2. Connect a serial cable to the serial port of the first switch.
3. Using any terminal utility, open a serial connection session to the switch.
4. Open your terminal emulator and configure it to use the serial port (usually COM1, but this may
vary depending on your system). Configure serial communications for 9600,N,8,1 and no flow
control.
5. Connect the optical cables between the fixed 10GbE module on the front of the N2000 switches.
See this configuration in Figure 1.
2.2 Delete startup configuration
Note: All configuration settings will be deleted

console#reload
Are you sure you want to reload the stack? (y/n) y
Note: The switch will reboot.
Follow the prompts shown below when the Main Menu is displayed during the bootup process.
