Reading the Status Indicators

The six symbols on the left side of the monitor panel are

status indicators. They are

backlit by colored light emitting diode (LED) lamps, and they work in conjunction

with the alarm horn to let you know the operating status of the UPS.

NORMAL

This green symbol is lit when the UPS is operating in

Normal mode. The power processing unit (PPU) is

supplying power to the critical load.

Battery

This yellow symbol is lit when the UPS is operating in

Battery mode. Because Battery mode is a normal

condition of the UPS, the Normal indicator also remains lit.

Bypass

This yellow symbol is lit when the UPS is operating in

Bypass mode. The critical load is supported by the

bypass source. The Normal indicator is not lit when the

system is in Bypass mode.

Notice

This yellow symbol is lit when the system needs attention.

The LCD screen shows all active notices. Some notices

may be accompanied by an audible horn. To silence the

horn, press the

and the

pushbuttons

simultaneously. The Notice indicator may be lit along with

other indicators.

Alarm

This red symbol is lit when a situation requires immediate

attention. The LCD screen shows the highest priority active

alarms. All alarms are accompanied by an audible horn.

To silence the horn, press the

and the

pushbuttons simultaneously. The Alarm indicator may be

lit along with other indicators.

Standby

This yellow symbol is lit when electricity is present in the

PPU of the UPS and the Normal indicator is not lit. During

normal startup, this indicator illuminates until the the UPS

transfers to Normal mode, at which point the Normal

indicator is lit. During normal shutdown, the Standby

indicator is lit until all energy in the UPS is dissipated and

shutdown is complete.

For more information about audible horns, refer to the “System Event Horns” section

of Chapter 12.
To test the LED lamps behind the status indicators, press the

and

pushbuttons simultaneously for 3 seconds. All the indicators should light while you

hold down these pushbuttons. If any indicator does not light, its LED may need to

be replaced. Contact Customer Service if you have a problem with the indicator

lamps.
