Server Administrator Change Management MIB
The Server Administrator Change Management MIB (filename dellcm.mib) provides management data that allows you to monitor the
inventory of devices and applications with SNMP management applications.
The following table describes each Server Administrator Change Management MIB group and lists the MIB group number assigned to the
MIB group. The Server Administrator Change Management MIB groups are identified by the SNMP OID 1.3.6.1.4.1.674.<MIB group
number> where <MIB group number> is the MIB group number assigned to the MIB group. See the relevant section for more information
about the MIB objects defined in a MIB group.

Basic Terminology
It is important to have a good understanding of the key technical terms used in this guide. This guide provides definitions for all essential
terms used in describing the Server Administrator MIBs. For definitions on all essential terms and acronyms, see the Glossary available on
the Dell Support website at dell.com/support/manuals.
Frequently Used Terms in Variable Names
The following terms are frequently used in the name of a MIB variable:
Capability refers to the actions an object can perform, or to actions that can be taken by the object. Hot-pluggable is an example of a
capability. If a card is hot-pluggable, it can be replaced while a system is running. Capability settings refer to the capabilities of the object
that the user can select from and activate if desired. Capability settings allow users of the server administrator to predetermine how an
object behaves under specific conditions.
Settings are the conditions of a manageable object that determine what happens when a certain value is detected in a component. For
example, a user can set the upper critical threshold of a temperature probe to 75 degrees Celsius. If the probe reaches that temperature,
the setting causes an alert to be sent to the management console. Some settings, when reached, can trigger a system shutdown or other
response to prevent damage to the system.
State refers to the condition of an object that has more than one condition. For example, an object may be in a not ready or in an enabled
state.
Status refers to the health of an object or how the object is functioning. For example, the status of a temperature probe that is
measuring acceptable temperatures would be reported as normal. When the probe begins reading temperatures that exceed limits set by
the user, it reports a critical status.
Tables
This reference guide contains two types of tables: tables that are used to organize and define variable values and tables that define MIB
objects. Readers must understand the difference between these two types of tables.
SNMP Tables
Most of the MIB objects defined in this reference guide are organized into SNMP tables. SNMP tables organize data into two-dimensional
structural arrays. In SNMP, objects that have a relationship to other objects are called columnar objects. Columnar objects are objects
used to form lists and tables. When a MIB group is divided into one or more discrete tables, the word table has a technical meaning. An
example is the section of this reference guide entitled Universal Unique Identifier (UUID). The UUID object has a type and a value that
uniquely identifies an object such as a chassis. The table defines all of the variables that comprise the managed object UUID.
The following table is an example of an SNMP table. The table contains variables that must occur in a definite sequence. In the example
table the defined variables are UUID Chassis Index, UUID Index, UUID Type, and UUID Value.
These objects comprise the Server Administrator definitions for the UUID.
