UART pinout for MS22P? #14

Closed networkdawg closed 4 years ago

networkdawg commented 4 years ago

I opened up my MS22P switch yesterday, and am trying to figure out the jumper layout for it. I suspect J3 is the UART pins, but looking for confirmation as I didn't get any serial response from it.

halmartin commented 4 years ago

You're the first person (that I'm aware of) to try this on an MS22P. I don't know the UART pins. Are you able to email me (or imgur) high resolution photos of the PCB?

networkdawg commented 4 years ago

@halmartin I have uploaded a bunch to Google Photos. https://photos.app.goo.gl/ngTeMSfBnakoKgW16

I suspect it is J3, however I discovered the pin that I believe is GND, has no solder holding it to the board, so the pin just pushes through. I am going to tack on a small dab of solder and see if I can get any serial response then.

halmartin commented 4 years ago

I would guess UART is J4, on the left side of the board.

You should confirm with a voltmeter that none of the pins of J4 have greater than 3.3V present (with the switch powered on) and then connect a UART adapter with the usual pinout:

  1. VCC (don't connect)
  2. Uart Tx
  3. Uart Rx
  4. GND

Do not use the resistance/connectivity test on your meter, as you will damage the SoC!

Please also be careful when measuring, as J4 appears to be near the PoE injection board, which carries 57VDC. For added safety, you should disconnect the PoE power cable (blue/black) while probing J4.

For testing J3, you can just unplug one of the fans and use the ground pin of the fan for your UART connection.

JY1 and JY2 probably map to the pins of the SOIC16, as the MS22 has a PCB layout similar to the MS42. In that case, pin 1 of JY1 may be GND.

networkdawg commented 4 years ago

@halmartin you were correct. UART is J4. GND is the pin closest to the front of the switch. I have the bootlog for it.

Thanks for confirming the UART header and providing your boot log.

Is it possible to get a photo of the whole board mounted inside the chassis? Then I can annotate the board photo and add it to the installation doc.

For example, this is the internals of the MS220-24P: MS220-24-SOIC

networkdawg commented 4 years ago

@halmartin I have added a few more photos in my album shared above. I believe the SOIC16 is right beside the right hand heat sink.

halmartin commented 4 years ago

Thanks! I've added the MS22P to the installation instructions.
