Are there any LEDs illuminating near the switches? if no, this means that the ups is off. switch the ups on by pressing the ON button momentalily until the start of the second beep then release it. the ups will do a self test then it will stabilise after a few second. if it does not come ON, connect the ups to power then attempt to switch it on. if it comes ON then you have to check the integllity of the batteries. if it still does not give power then you have to call the APC service enginneer in your region .
