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 daisychained 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.

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
.
