Apollo BTC for newbies

hey everyone today I set up my Apollo full node along with a regular Apollo. At first, everything was working great and I could access the dashboard... then I updated the dashboard to version 0.3.4. After that, I navigated around the dashboard and noticed the node wasn't running. I tried to start it and waited around 5-15 minutes, but nothing happened. So, I decided to check the m.2 card and shut down the Apollo from the dashboard. The m.2 was fine, so I powered everything back on... since then, it’s not showing up on the network. The red LED is lit, but the fan isn't running. I plugged in an HDMI monitor and a mouse, but the monitor isn't getting a signal. Is there a power button somewhere? What are those tiny buttons on the board for? Thanks for any help!

Since you disconnected the m.2 recently then there is a possibility that you inserted the m.2 drive incorrectly. You can try these steps: - unplug the m.2 drive again and insert it back to the unit. - If it didn't work unplug it again and check the terminals and maybe there are some dirt and rust clean it using a pencil eraser or isopropyl alcohol then replug it again and test.
