One of the key functions that the data network supports is discovery of operating systems on

the various network endpoints. Discovery of operating systems by the FSM is required to

support software updates on an endpoint such as a compute node. The FSM Checking and

Updating Compute Nodes wizard assists you in discovering operating systems as part of the

initial setup.

3.2 Chassis Management Module

The CMM provides single-chassis management, and is used to communicate with the

management controller in each compute node. It provides system monitoring, event

recording, and alerts, and manages the chassis, its devices, and the compute nodes. The

chassis supports up to two chassis management modules. If one CMM fails, the second CMM

can detect its inactivity, activate itself, and take control of the system without any disruption.

The CMM is central of the management of the chassis, and is required in the Enterprise

Chassis.

The following section describes the usage models of the CMM and its features.

For more information, see 4.8, “Chassis Management Module” on page 82.

3.2.1 Overview

The CMM is a hot-swap module that provides basic system management functions for all

devices installed in the Enterprise Chassis. An Enterprise Chassis comes with at least one

CMM, and supports CMM redundancy.

The CMM is shown in Figure 3-2

Tip: If you want, the management node console can be connected to the data network for

convenient access.
