Basic Terminology
It is important to have a good understanding of the key technical terms used in this guide. This guide provides denitions for all
essential terms used in describing the Server Administrator MIBs. For denitions 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 specic 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 dene variable values and tables that dene
MIB objects. Readers must understand the dierence between these two types of tables.
SNMP Tables
Most of the MIB objects dened 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 Identier (UUID). The UUID object has
