Users Guide

You can add member chassis to an MCM group in two ways:
● Automatic—Enables automatic inclusion of the member to the chassis group. The automatic inclusion process does not
require approval from the chassis administrator.
● Manual—Mandates approval by the chassis administrator to include the member chassis to the chassis group.
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
NOTE:
If any of the issues that are listed above occur, the management network access to all components in the
daisy-chained group may be interrupted for up to 10 minutes. The OME - Modular web interface recovers automatically.
The wired chassis are displayed as under Available Chassis in the Group Deployment Wizard.
