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). Case [Page 2]

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." ::= { upsAlarm 2 } upsAlarmEntry OBJECT-TYPE SYNTAX UpsAlarmEntry MAX-ACCESS not-accessible STATUS current DESCRIPTION "An entry containing information applicable to a Case [Page 14]
