Troubleshooting

This chapter provides some information to assist you in troubleshooting the UPS. Using it
will help you determine the urgency of the condition and possible actions to take. These
are the topics in this chapter.

• Troubleshooting aids

• RS-232 UPS port does not respond

• Overtemperature considerations

• Alarm indicators

• Normal and abnormal UPS conditions

Figure 6-1 shows the different combinations of indicator lights and warning alarms that
can occur on a UPS as well as the conditions (cases) under which these lights and alarms
activate. The discussion of each case provides a meaning, a cause, and suggested actions.

WARNING

If there is any action or procedure you do not understand, or are not
qualified to perform, do not attempt to perform it.
