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 Cell16 ?
A.
SNMP v1.
Q. How do I configure the Cell16 to send traps to an SNMP manager? Is there a separate MIB for the
Cell16 ? 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 Cell16 begins sending traps as soon as the SNMP managers are defined. The Cell16 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 Cell16 support MIB-2 and/or any other standard MIBs?
A.
The Cell16 supports the bulk of MIB-2.
Q. Does the Cell16 SNMP agent support both Cell16 and T/MonXM variables?
A.
The Cell16 SNMP agent manages an embedded MIB that supports only the Cell16 '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 Cell16 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 Cell16 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 Cell16 and the SNMP manager are both on the network. Use the unit's ping command to ping
the SNMP manager.
