[Steve / Kiwamu]
When Steve was working on the strain reliefs on 1X5 he found that some LEDs on the back side of the binary IO boxes were off.
There are 4 binary IO boxes and their power are directly supplied from Sorensens. According to the display of the Sorensens, the power are correctly generated.
Steve and I checked a picture of the boxes taken before he started working and we found it's been like this.
It might be just a problem of the LEDs or the fuses are blown, but anyway it needs an inspection.
Here is a picture of the back side of the boxes. You can see some LEDs are on and some are off.
