HP R12000 XR - Manual (Page 23)

Operation
Because a portion of the self-test requires battery power, the self-test will not be initiated if
the batteries are less than 90 percent charged. If the UPS detects a problem, the
Alarm LED (4) will be solid red (see Figure 2-3), and the UPS sounds an audible alarm.
NOTE: Refer to Chapter 5, “Troubleshooting,” for information on what to do if the self-test detects a
problem.
Audible Alarms
The UPS sounds an audible alarm to warn of a problem.
To identify the problem, select the Status option from the LCD Main Menu. The LCD will
display
X Alarms on the top line, where X is equal to the number of alarms. The bottom row
will describe the nature of the alarm condition. Scroll through multiple alarms using the up
and down arrow keys on the Center button. Refer to the section, “Displaying the Status or
Active Alarms,” in Chapter 3 for more information on displaying the alarms using the LCD
menu.
The Main Menu displays active alarms for the entire system. Under the electronics modules
M1-M4 menus, only the individual electronics modules that have alarms are indicated. As a
result, you can pinpoint individual modules that are having problems.
Refer to the section, “LCD Alarm Troubleshooting,” in Chapter 5 for causes and suggested
actions for all alarm conditions.
Silencing an Audible Alarm
To silence the alarm, press the Test/Alarm Reset button (1) and hold for one second.
