The Raspberry Pi 3B+ has 4 indicator lights that can help you identify when there are hardware problems.
- Next to the micro USB port used for the power cable there are two lights: one red & one green
- Red LED, labeled "PWR" on the circuit board
- a steady red light means the power supply is good.
- flashing, blinking, or off completely means that the power supply is not providing sufficient power.
- Green LED, labeled "ACT" on the circuit board
- irregular flashes are normal and happen whenever the player accesses its memory
- a steady green light when booting up means a missing or bad microSD card
- Red LED, labeled "PWR" on the circuit board
- On the ethernet port there are two indicator lights:
- Both lights will be off if the player is using WiFi
- Yellow LED ethernet socket left
- on = 100-Mbps connection
- off = 10-Mbps connection
- Green LED, ethernet socket right
- on = link established
- flashes during port activity
- off = no link is established via ethernet
