1. Introduction
This memo defines a portion of the Management Information Base (MIB)
for use with network management protocols in the Internet community.
In particular, it defines objects for managing uninterruptible power
supply (UPS) systems.
Case PAGE 1 
RFC 1628 UPS MIB May 1994
2. The SNMPv2 Network Management Framework
The SNMPv2 Network Management Framework consists of four major
components. They are:
o RFC 1442 which defines the SMI, the mechanisms used for
describing and naming objects for the purpose of management.
o STD 17, RFC 1213 defines MIB-II, the core set of managed
objects for the Internet suite of protocols.
o RFC 1445 which defines the administrative and other
architectural aspects of the framework.
o RFC 1448 which defines the protocol used for network access
to managed objects.
The Framework permits new objects to be defined for the purpose of
experimentation and evaluation.
2.1. Object Definitions
Managed objects are accessed via a virtual information store, termed
the Management Information Base or MIB. Objects in the MIB are
defined using the subset of Abstract Syntax Notation One (ASN.1)
defined in the SMI. In particular, each object type is named by an
OBJECT IDENTIFIER, an administratively assigned name. The object
type together with an object instance serves to uniquely identify a
specific instantiation of the object. For human convenience, we
often use a textual string, termed the descriptor, to refer to the
object type.
3. Overview
This document defines the managed objects for Uninterruptible Power
Supplies which are to be manageable via the Simple Network Management
Protocol (SNMP).

SYNTAX SEQUENCE OF UpsAlarmEntry
MAX-ACCESS not-accessible
STATUS current
DESCRIPTION
"A list of alarm table entries. The table contains
zero, one, or many rows at any moment, depending upon
the number of alarm conditions in effect. The table
is initially empty at agent startup. The agent
creates a row in the table each time a condition is
detected and deletes that row when that condition no
longer pertains. The agent creates the first row with
upsAlarmId equal to 1, and increments the value of
upsAlarmId each time a new row is created, wrapping to
the first free value greater than or equal to 1 when
the maximum value of upsAlarmId would otherwise be
exceeded. Consequently, after multiple operations,
the table may become sparse, e.g., containing entries
for rows 95, 100, 101, and 203 and the entries should
not be assumed to be in chronological order because
upsAlarmId might have wrapped.
Alarms are named by an AutonomousType (OBJECT
IDENTIFIER), upsAlarmDescr, to allow a single table to
reflect well known alarms plus alarms defined by a
particular implementation, i.e., as documented in the
private enterprise MIB definition for the device. No
two rows will have the same value of upsAlarmDescr,
since alarms define conditions. In order to meet this
requirement, care should be taken in the definition of
alarm conditions to insure that a system cannot enter
the same condition multiple times simultaneously.
The number of rows in the table at any given time is
reflected by the value of upsAlarmsPresent."
