ULP EMS Operator Guide Maintaining and Operating the ULP Network
On-Ramp Wireless Confidential and Proprietary 41 010-0045-00
 Four missed intervals trigger a major alarm.
 Five missed intervals trigger a critical alarm.
NOTE:
To guarantee that EMS operators receive RMU network alarms before CIMA
operator alarms, modify the alarms to be 1, 2, and 3 instead of 3, 4, and 5. Using
these settings will enforce that EMS operators must clear network issues before
they propagate to CIMA operators. This configuration guarantees that the NMS
operators will be the first responders to system events and have time to debug/clear
up any ULP issues prior to the alarm elevating to the application operator level.
The RMU obstruction light update interval is 24 minutes. With settings of 1, 2, and 3 as
discussed above, these alarms would correspond to a RMU that is missing 24, 48, or 72 minutes
of updates respectively.
The update interval for FCIs is one per day. With settings of 1, 2, and 3, these alarms would
correspond to an FCI that is missing 1, 2, or 3 days of daily updates.
If an end device reports missed update interval alarms, it may be a network or device specific
issue.
While debugging this issue, contact the CIMA operator and inform them that there are end
devices alarming on the network side. If an end device is missing EMS update intervals, it may be
flagged in the CIMA system if the application CIMA missed interval alarm is configured as having
the EMS and CIMA alarm intervals overlap.
If the EMS alarm is based on a single end device, and the CIMA operator confirms a CIMA alarm,
the CIMA operator should confirm missed update intervals and provide other information that
can explain the outage. For example, the FCI reporting this error may need a battery
replacement, or the RMU reporting this event may have an issue with its battery charging
system. If the problem cannot easily be described as a known issue with an FCI or RMU, the
problem may be network related. The operator should schedule a service call. The appropriate
On-Ramp Wireless personnel may come on site to get additional information from the EMS
system. The On-Ramp Wireless personnel may also direct an EMS operator to enable additional
debugging aspects of the device through the EMS console.
To clear the problem, reboot the GW and/or AP. This may or may not solve the immediate issue.
3.6.1.9 Sysmon Node Communications
The Sysmon is a dedicated end device that monitors an AP in the ULP network. Typically, there is
one Sysmon per AP.
If a Sysmon alarm occurs, it is most likely due to a ULP network issue. The operator should
schedule a service call. The appropriate On-Ramp Wireless personnel may come on site to get
additional information from the EMS system. The On-Ramp Wireless personnel may also direct
an EMS operator to enable additional debugging aspects of the device through the EMS console.
To clear the problem, reboot the GW and/or AP. This may not solve the issue.
