Table 1 identifies which status and error LEDs that display on the 2145 UPS-1U front-panel assembly relate to the specified error conditions. It also lists the uninterruptible power supply alert-buzzer behavior.

Table 1. 2145 UPS-1U error indicators
1 Load2	2 Load1	3 Alarm	4 Battery	5 Overload	6 Power-on	Buzzer	Error condition
Green (see Note 1)					Green	(see Note 3)	No errors; the 2145 UPS-1U was configured by the SAN Volume Controller
Green	Amber (see Note 2)				Green		No errors; the 2145 UPS-1U is not yet configured by the SAN Volume Controller
Green	Either on or off		Amber		Green	Beeps for two seconds and then stops	The ac power is over or under limit. The uninterruptible power supply has switched to battery mode.
		Flashing red	Flashing amber	Flashing red	Flashing green	Three beeps every ten seconds	Battery undervoltage
Green	Either on or off	Flashing red			Flashing green	Solid on	Battery overvoltage
		Flashing red	Flashing amber		Flashing green	Solid on	Output wave is abnormal when the charger is open, on battery mode
		Flashing red	Flashing amber			Solid on	The ac-power output wave is under low limit or above high limit on battery mode
Green	Either on or off		Amber			Beeps for four seconds and then stops	On battery (no ac power)
Green	Either on or off		Flashing amber			Beeps for two seconds and then stops	Low battery (no ac power)
Green	Either on or off			Red	Green	Beeps for one second and then stops	Overload while on line
			Amber	Red		Beeps for one second and then stops	Overload while on battery
Either on or off	Either on or off	Flashing red			Green	Solid on	Fan failure
Either on or off	Either on or off	Flashing red	Amber			Solid on	Battery test fail
		Flashing red		Red		Solid on	Overload timeout
		Flashing red	Amber		Green	Solid on	Over temperature
		Flashing red	Amber	Red	Green		Output short circuit
Notes: The green Load2 LED ( 1 ) indicates that power is being supplied to the right pair of ac-power outlets as seen from the rear of the 2145 UPS-1U. The amber Load1 LED ( 2 ) indicates that power is being supplied to the left pair of ac-power outlets as seen from the rear of the 2145 UPS-1U. These outlets are not used by the SAN Volume Controller. This LED might be illuminated during power-on sequences, but it is typically extinguished by the SAN Volume Controller node that is attached to the 2145 UPS-1U. A blank cell indicates that the light or buzzer is off.
