If the alarm input is normally open, switching to Reversed operation converts it to a normally closed alarm
point.
If the alarm input is normally closed, switching to Reversed operation converts it to a normally open alarm
point.
Q. I'm unsure if the voltage of my power supply is within the specified range. How to I test the voltage?
A.
Connect the black common lead of a voltmeter to the ground terminal of the battery. Connect the red lead of the
voltmeter to the batter's VCD terminal. The voltmeter should read b12 and +30VDC.
SNMP FAQs 17.2
Q. Which version of SNMP is supported by the SNMP agent on the NetGuardian?
A.
SNMP v1, SNMPv2 and SNMPv3.
Q. How do I configure the NetGuardian to send traps to an SNMP manager? Is there a separate MIB for
the NetGuardian? How many SNMP managers can the agent send traps to? And how do I set the IP
address of the SNMP manager and the community string to be used when sending traps?
A. The NetGuardian begins sending traps as soon as the SNMP managers are defined. The NetGuardian MIB can
be found on the DPS Telecom website. The MIB should be compiled on your SNMP manager. (
Note: MIB
versions may change in the future.) The unit supports 2 SNMP managers, which are configured by entering its
IP address in the Trap Address field of Ethernet Port Setup. To configure the community strings, choose SNMP
from the Edit menu, and enter appropriate values in the Get, Set, and Trap fields.
Q. Does the NetGuardian support MIB-2 and/or any other standard MIBs?
A.
The NetGuardian supports the bulk of MIB-2.
Q. Does the NetGuardian SNMP agent support both NetGuardian and T/MonXM variables?
A.
The NetGuardian SNMP agent manages an embedded MIB that supports only the NetGuardian's RTU variables.
The T/MonXM variables are included in the distributed MIB only to provide SNMP managers with a single MIB for
all DPS Telecom products.
Q. How many traps are triggered when a single point is set or cleared? The MIB defines traps like "major
alarm set/cleared," "RTU point set," and a lot of granular traps, which could imply that more than one
trap is sent when a change of state occurs on one point.
A. Generally, a single change of state generates a single trap.
Q. What does "point map" mean?
A.
A point map is a single MIB leaf that presents the current status of a 64-alarm-point display in an ASCII-
readable form, where a "." represents a clear and an "x" represents an alarm.
Q. The NetGuardian manual talks about control relay outputs. How do I control these from my SNMP
manager?
A. The control relays are operated by issuing the appropriate set commands, which are contained in the DPS
Telecom MIB.
Q. How can I associate descriptive information with a point for the RTU granular traps?
A.
The NetGuardian alarm point descriptions are individually defined using the Web Browser.
Q. My SNMP traps aren't getting through. What should I try?
A.
Try these three steps:
1. Make sure that the Trap Address (IP address of the SNMP manager) is defined. (If you changed the Trap
Address, make sure you saved the change to NVRAM and rebooted.)
2. Make sure all alarm points are configured to send SNMP traps.
3. Make sure the NetGuardian and the SNMP manager are both on the network. Use the unit's ping command
to ping the SNMP manager.
