There is a Sun Spac T5440 that supports a legacy POS system, and was first brought on line in 2010. In tha time line it ran almost without flaw. There had been little if any maintenance performed, and nothing had been added to the original hardware.
The system failed the day after Thanksgiving. Thus far little progress has been made to communicate with the device. Each attempt has met with failure. there isn't a monitor on the unit. Does this unit require a proprietary monitor configuration?
On the back the Amber Exclamation light is lit. The light for the power is lit solid green. We are hoping that we are dealing with a power issue. The poer supplies, of which there are four of them, display a green light that rolls from 1-4. these lights display in rolling fashion one after another in rapid sequence. See video.
