Linksys LGS116P Bilnking Blue Light

[Special]

I have a LGS116P switch that has a blinking blue light and nothing else. Does anyone have a firmware or advice to try and get this up and running?
The switch looks to have a 4 pin header installed and two other unpopulated 4 pin spots for more headers.
First unpopulated header has [CLK GND DAT VCC] and other has [VCC GND TX RX].
The populated header has nothing listed.

In case someone is interested it wasn't a problem with the switch instead the power supply was bad.
