Dell OpenManage Enterprise-Modular Edition Version 2.00.00 for PowerEdge MX7000 Chassis User's Guide

Prerequisites for creating a wired group

Following are the prerequisites to create a wired or daisy-chained chassis group:

• List of wired daisy-chained chassis—All the chassis must be on the private stack. You need not enter a password as the machine to machine authentication trust is used.
• Ensure that you have added member chassis to the group using the automatic or manual method.
• Ensure that the chassis settings are selected for applying to the other chassis—Power, user authentication, alert destination, time, proxy, security, network services, local access.
• Ensure that Auto Negotiation is set to true in all the chassis that are connected to form an MCM group. For more information, see Configuring chassis network.
• Before stacking the chassis for creating a group or adding new members to the existing group, ensure that all the chassis have the same OME-Modular firmware version.

Before creating an MCM group, ensure that the MX7000 management networks are wired together in a stacked configuration. The stacked configuration helps in surviving:

• A single network cable failure
• A single management module failure
• Power loss owing to any chassis in the stack
• Failover of a chassis in the stack

The wired chassis are displayed as under Available Chassis in the Group Deployment Wizard.
