RB4011 Light Stuck On

Thu Jan 02, 2020 10:05 pm

I have a RB4011iGS+ running RouterOS 6.43.7 which appears to be malfunctioning. Here's what happened:
  1. The router stopped being responsive and would not permit access using WinBox, HTTP, or Telnet.
  2. The router began introducing latency on the network and stopped forwarding some traffic.
  3. The activity light for port 10 lit up solid, although there is nothing plugged into the port.
  4. Power cycling the router resolved the latency issue.
  5. After rebooting, the activity light for port 10 continues to light up solid (no blinking).
I did have some mangle rules logging for a while, and I suspect the log in memory may have grown too large and caused the latency. You would think that the software would manage the memory so that log overrun would not be possible. At he same time, the port 10 light is still concerning. Does this represent a hardware failure, or some correctable software problem?

I noticed if I power the RB4011 from a 48volt power supply on the back, the led of port 10 stay on.

If it powered via the included power supply, it doesn't do it.

Also, if it powered from a CRS112 via PoE-in with a 48volt power supply only, the port 10 doesn't light as well.

Why not? It's a standard telecom voltage and most (if not all?) MTs support it. RB4011 goes up to 57V and I have a few on 48V supply as they're connected to the same distribution block as other devices. It lets us use thinner wires and is more immune to voltage drop.
