Nucleus Rev B
Description of Issue
The Nucleus is in an endless cycle of showing two screens, the “Uh oh, something’s not right” screen and the half-circle with blinking vertical lines screen. It switches from one to the next, holding each for several minutes. It’s been stuck in this cycle for 3 days.
I connected my tv to the Nucleus hdmi port A, and got a screen that simply lists the manufacturer, model, OS, serial (which is 48210B25D56A), and hostname. There are instructions to access the OS Web UI at http//10.0.0.154/, which I did.
That web page states that the system status for everything on the Nucleus is “OK”. I stopped the software, reinstalled the operating system and restarted the software, and nothing changed. I still have nothing but the cycle of two screens.
When I first got the Nucleus, about 3 weeks ago, I had this same problem after I had transferred around 1.5tb of music to the Nucleus internal SSD. I fixed the problem by resetting everything in the OS Web UI, including reformatting the SSD. So I’ve had to redo the music transfer. I have around 8,000 albums, stored as FLAC files which take a little under 3tb of storage. This time I transferred a little over 2tb of files before the Nucleus crashed. I don’t want to reformat the SSD and start transferring files again.
After the first crash and total reset and reformat of the SSD, I’ve been transferring files one album at a time, to make sure I catch corrupt files. I don’t know if corrupt files are causing the crashes, but I’ve had a few so far that didn’t. Loading one file at a time is painstaking, and ultimately didn’t keep the Nucleus from crashing.
RAM & Internal Storage
The internal storage is 4tb, with around 2tb filled. I don’t know the RAM.
Connected Audio Devices
The Nucleus is connected with a short ethernet cable directly to a Comcast modem/router. The router is hardwired to my laptop using a decent 24awg ethernet cable. My laptop is connected by usb cable to a Schiit DAC. I have RoonBridge software running on the laptop.
Home Network Details
I don’t see a make or model number on the modem/router combo. It only has a label on top that reads “Xfinity.” I described the connections to the Nucleus in the previous section. They’re simple, and nothing in my system uses wifi.
