C Configuring SNMP Access for Monitored Service LAN
Devices
Starting with OSM T0682 H02 AAY and later, SNMP access information is required to start
monitoring a UPS or maintenance switch.
• For a UPS, you must enter the appropriate community strings for both the SNMP Read Access
Community and SNMP Write Access Community.
• For a maintenance switch, you must enter the appropriate community string for the SNMP
Read Access Community.
The community string and its associated access privileges for both SNMP Read Access Community
and SNMP Write Access Community are established by the administrator for each device.
OSM assumes the default community string for each device (listed in the sections that follow). If a
device was started with other values prior to upgrading to T0682 H02 AAY (or later), OSM reports
the device as Not Responding and the repair action instructs you to stop monitoring the device,
then perform the Start Monitoring UPS or Start Monitoring Maintenance Switch action using the
SNMP community string(s) as set by the administrator.
The following sections describes how an administrator can change default values for:
• “SNMP Read/Write Access for UPS”
• “SNMP Read Access for Maintenance Switch”
SNMP Read/Write Access for UPS
The default values for SNMP Read and Write Access are:
AccessCommunity String
Information Required by the Start
Monitoring UPS Action
Read OnlypublicSNMP Read Access Community
Read/WriteprivateSNMP Write Access Community
An administrator for the UPS can modify the default community strings and their associated access
privileges by following these steps:
NOTE: If OSM is currently monitoring the UPS, use the Stop Monitoring action (located under
the UPS object) before making changes to the SNMP configuration.
1. Initiate a telnet session with the IP address of the UPS.
