Zyxel 1920-48HP

Sys light blinking. I have recently inherited a ZyXEL 1920-48HP POE. This is the problem:

(Sorry about the high rez, phone was set to high rez recording)
I'm aware there are no external console ports for this unit, but this looks like other switches I have encountered, some of which had access to console ports internally as long as you had an adapter. Does anyone know if I can get further info from this switch, do a further reset with jumpers inside, or have a factory service manual. This is for a non-profit legal assistance org to the poor, they don't have a huge amount of budget they need their hardwear working. Any help would be super welcome.
