registered, each community containing one or more host names and IP addresses. These
hosts can be trusted and can read information from the UPS. If you want to control the UPS via
SNMP, you must register the NAS server in one of the communities listed, then enter the name
of the community in the
“
UPS community
”
field.
4. UPS enterprise OID
This setting can be found in the MIB file of the UPS. If the UPS supports SNMP access, the
manufacturer has added an MIB file to the documentation. Download the file from the
manufacturer
’
s web site if necessary. Look in the file for the
“
Private Enterprise Number
”
.
APC
’
s Private Enterprise Number is 318, so the value of this field should read 1.3.6.1.4.1.318 ,
whereby 1.3.6.1.4.1 is static and must not be changed. You can also use an SNMP program
such as HP OpenView to browse through the MIB file and retrieve the
“
Private Enterprise
Number
”
.
5. Battery Status OID
This setting refers to the
“
battery status OID
”
in the MIB file. The value for the APC UPS is
1.3.6.1.4.1.318.1.1.1.2.1.1 . Enter this value, or the short form 1.1.1.2.1.1 , if you are using an
APC product.
6. Normal status
The
“
battery status OID
”
(see above) obtained from the MIB file represents a number of states,
e.g., 2 for
“
battery normal
”
, 1 and 3 for
“
unknown
”
or
“
low battery
”
respectively.
After items 5 and 6 are filled up, the system will probe the UPS in the interval chosen above
and shut down in 5 seconds if abnormal battery status is detected.
7. Registered UPS event trap OID pairs
A UPS with SNMP faculties usually has a trap function, used to detect anomalies in the UPS
status without waiting for the scheduled probing signal. Click
“
Edit trap
”
to add or delete event
trap OIDs for your UPS.
