X. Troubleshooting
1.
General
Problem: On some Computer Main boards the COM ports are mixed up, therefore it is possible that COM 1 under NOVELL is
actually COM 2 under NT etc. So if any communication problems exist, configure the software intentionally on the
”wrong” com port and try again. This problem is known from some ASUS, Acer, GigaByte and SIEMENS Main
boards out of production 1997.
2.
All operating systems
Problem: Error message: ”Ups communication lost.”
Answer: There is no COM-Port available, check the COM-Port, the settings in CMOS and System-Setup.
Problem: During the system boot, the UPS Management software starts and the UPS turns off.
Answer: To guarantee the correct function of UPSMON Software use the default settings for the UPS model or the serial port-
type, this problem can also be caused by a wrong cable-connection.
Problem: In the logfile of UPSMOM the message "Communication lost, communications restored" occurs.
Answer: Some of the data from the UPS is not correct or the bytes of software received where damaged. This may be the
result of external effects on the cables or the UPS. Check the cable, cable length and the communication parameters.
Check if any background software that is using the com ports is active. (e.g. Virus checker within NetWare, or
others). If this message occurs periodically, it is not a critical event. Only if this message occurs continuously for a
longer period should you contact the UPS software/hardware support.

Troubleshooting Novell NetWare
Problem: ASUS P5HX/B (series 1997) does not accept any NOFIFO Parameters at NOVELL AIOCOMX Commands.
Answer: Node Parameter Problem with Novell NetWare: If AIOCOMX is installed and responds with the message "loaded
aiocomx 2F8 on port 36789690 " the node parameter, e.g. NODE=1, has to be specified otherwise the serial port will
not work.
Problem: The UPSMON Software could not establish the communication to the UPS.
Answer: You may have configured a port which is not found by aiocomx.nlm. Check the ports offered by aiocomx.nlm. Pay
attention to the screen display when starting aiocomx.nlm. If aiocomx.nlm has been started, unload aiocomx.nlm and
start it again to check the parameters. Check if other modules are using aiocomx.nlm (like fax software, time
synchronising modules, etc…).
Problem: I receive the error message: ”Loader cannot find public symbol”.
Answer: Has SNMP been loaded before the start of the UPS service? Check the SNMP-Version. From version 2.08 on
communications is possible. Please use a CLIB.NLM that is able to work with SNMP.NLM.
Problem: I receive the error message: ”Communication lost”.
Answer: Upsagent can not identify the protocol.
