6.2.1 Overview of the Chassis Management Module
The Chassis Management Module (CMM) is a hot-swap module that provides
system management functions for all devices installed in the Enterprise Chassis.
An Enterprise Chassis comes with at least one CMM and supports module
redundancy. Only one module is active at a time.
Systems management of either a single chassis or multiple chassis can be
performed directly through the CMM or through the IBM Flex System Manager.
Using the CMM is only useful for base management tasks. We describe IBM Flex
System Manager in 6.4, “IBM Flex System Manager” on page 192.
Through an embedded firmware stack, the CMM implements functions to
monitor, control, and provide external user interfaces to manage all chassis
resources. These functions include:
򐂰 Functionality similar to Advanced Management Module (AMM)
in BladeCenter
򐂰 Single chassis management
򐂰 The Chassis Management Module initial setup wizard
򐂰 An IMMv2-based hardware engine
򐂰 Optional redundancy
򐂰 A Chassis Management Module service advisor
򐂰 Compatibility with earlier versions of BladeCenter CLI and SNMP
򐂰 Support for IBM Feature on Demand
򐂰 Support for IBM Fabric Manager
The CMM automatically detects installed modules in the Enterprise Chassis and
stores vital product data (VPD) on them.
Chassis Management Module default network information
The CMM does not have a fixed static IPv6 address by default. Initial access to
the CMM in an IPv6 environment can be done by either using the IPv4 IP
address or the IPv6 link-local address. The IPv6 link-local address is
automatically generated, based on the MAC address of the Chassis
Management Module. By default, the Chassis Management Module is configured
to respond to Dynamic Host Configuration Protocol (DHCP) first, before using a
static IPv4 address.
