HP r12000 xr User Manual

This chapter serves as a troubleshooting guide when problems occur with the UPS. Solutions 
for main and electronics module alarms are provided, as well as general solutions for UPS 
problems that occur both during and after startup.  

Table 5-1 lists the possible alarms of the main module or electronics modules. When these 
alarms occur, the LCD displays the number and type of alarms. An audible alarm may also 
sound. For each alarm listed in the table, an explanation of the cause is provided, as well as a 
recommended action to take to resolve the problem. 

As shown in Table 5-1, x Alarms on the first line of the LCD display means that one or more 
alarms are present, with the variable x indicating the number of alarms. The type of alarm is 
displayed on the second line of the LCD. In Example 5-1, three alarms are present. The 
Fan Failure alarm has occurred, as well as two other alarms. Use the arrow keys on the 
Center button to scroll through the rest of the alarms list.
