Power-on indicator
The power-on indicator is displayed when the 2145 uninterruptible power
supply-1U (2145 UPS-1U) is functioning.
When the power-on indicator is a steady green, the 2145 UPS-1U is active.
On/off button
The on/off button turns the power on or turns the power off to the 2145
uninterruptible power supply-1U (2145 UPS-1U).
Turning on the 2145 UPS-1U
After connecting the 2145 UPS-1U to the outlet, it will be in standby mode until
you turn it on. Press and hold the on/off button until the power-on indicator is
illuminated (approximately 5 seconds). A self-test is initiated that takes
approximately 10 seconds, during which time the indicators are turned on and off
several times. The 2145 UPS-1U then enters normal mode.
Turning off the 2145 UPS-1U
Press and hold the on/off button until the power-on light is extinguished
(approximately 5 seconds). This places the 2145 UPS-1U in standby mode. You must
then unplug the 2145 UPS-1U to power-off the unit.
Test and alarm reset button
Use the test and alarm reset button to start the self-test.
To start the self-test, press and hold the test and alarm reset button for three
seconds. This button also resets the alarm.
Note: This button is applicable to both the 2145 uninterruptible power supply
(2145 UPS) and the 2145 uninterruptible power supply-1U (2145 UPS-1U).
Overload indicator
The overload indicator lights up when the capacity of the 2145 uninterruptible
power supply-1U (2145 UPS-1U) is exceeded.
If the overload indicator is on, go to the 2145 UPS-1U MAP to resolve the problem.
On-battery indicator
The on-battery indicator glows yellow when the 2145 uninterruptible power
supply-1U (2145 UPS-1U) is powered by the battery. This indicates that the main
power source has failed.
If the on-battery indicator is on, go to the 2145 UPS-1U MAP to resolve the
problem.
Service indicator
If the service indicator on the 2145 uninterruptible power supply-1U (2145
UPS-1U) is flashing red, maintenance is required.
If the service indicator is on, go to the 2145 UPS-1U MAP to resolve the problem.
