About This Guide
Purpose of the Guide
Use this guide to assist you in managing APC® products that can be monitored and
configured with the Simple Network Management Protocol (SNMP).
Related Documents and Files
This guide describes how to use the PowerNet® MIB only.
• See the User’s Guide and any other documentation shipped with your APC product
for information about other interfaces you can use to manage that product.
• See the documentation provided with your Network Management System (NMS) for
information about your NMS.
• For information on product-specific OIDs, use a standard MIB browser to view their
descriptions in the MIB.
• For information on traps, open the .mib file itself and go to the consecutively
numbered traps at the end of the file.
For assistance with this or any other APC product, contact APC Worldwide Customer
Support.

PowerNet MIB Structure
Traps
Management Cards, APC devices, and APC agents can send traps to a Network
Management System (NMS) when specific events occur. The trap receiver definitions
that a particular Management Card, device, or agent uses determine which NMSs can
receive traps. The MIB provides the meaning of each trap.
See PowerNet MIB Traps.
OIDs
APC products than can use OIDs
PowerNet MIB OIDs allow an NMS to use its SNMP browser to manage the following:
• Any APC product that relies on an external, pre-installed, or embedded (built-in)
Management Card for its network interface and that has its SNMP access controls
set to allow an NMS to have SNMP access.
• A PowerNet Agent and the devices it controls. A PowerNet Agent has limited control
over a UPS and does not use SNMP access controls.
SNMP access controls
You can use the Web interface or control console of a Management Card or a device
with an embedded Management Card to define these SNMP access controls for up to
four SNMP communities (SNMPv1), four user profiles (SNMPv3), or both:
• Disable SNMP access to prevent access by any NMS (SNMPv1 and SNMPv3).
REFERENCE GUIDE

• Associate an NMS IP address to an SNMP community name (SNMPv1) or to a user
profile (SNMPv3) to limit access to only the defined NMS.

• Configure the access for an NMS to an SNMP community as write access, read
access, or no access (SNMPv1).
For more information on SNMP access controls, see the User’s Guide for
your Management Card or network-enabled device.
Structure of the OID hierarchy in the SNMP browser
The PowerNet MIB fits into a hierarchical structure within your SNMP browser’s
categories. For example, for an HP OpenView for Windows SNMP browser, the OID
categories from the top of the structure down to the top category of PowerNet MIB
OIDs are as follows:
• [iso] (for International Standards Organization)
• [org] (for organization)
• [dod] (for Department of Defense)
• [internet]
• [private]
• [enterprises]
• [apc] (for American Power Conversion)
Structure of the OID hierarchy in the PowerNet MIB
In the hierarchical structure of the PowerNet MIB, the [apc] category of OIDs is at the
top, and individual OIDs are in specific OID categories or within specific OID tables.
See Tabled OIDs.
There are two categories under [apc]:
• [products] for OIDs to manage specific products.
• [apcmgmt] for OIDs that affect the operation of hardware-based SNMP agents (for

example, Management Cards and MasterSwitch™ units).
See Manage Agents and Management Cards.

There are three categories under [products]:
• [hardware] contains sub-categories for each type of hardware product that you can
manage using PowerNet MIB OIDs.
• [software] contains one sub-category, [powerNetSubAgent], of read-only OIDs to
monitor a software PowerNet agent only.
See Manage Agents and Management Cards.
• [system] contains read-only OIDs that identify models of APC UPSs and other APC
devices by unique numbers that other OIDs can reference. For example, the system
OIDs in other OID categories of the PowerNet MIB use a PowerNet MIB [system]
OID number for the MIB-II’s [sysObjectID] value.
Tabled OIDs
For any PowerNet MIB OID category listed in the SNMP browser, you can access a list
of the current values for all OIDs in that category and in all sub-categories below it in
the hierarchy, except OIDs grouped in a table. To access the current values of OIDs in
an OID table, select the OID table (always enclosed in braces {}) in the SNMP browser .
For example, to access the OIDs that define all four trap receivers that you can
configure through SNMP for a device, select {mconfigTrapReceiverTable} in the
SNMP browser.
