The thread linked above was what kicked off the search for the 7250s; estimated delivery is now monday. Will update with status post delivery. It may be a few days longer if I can't rustle up an appropriate console cable.

I think it has a mini-USB Type B management port. Basically shows up as a USB to serial adapter and you can just use that to bootstrap

(I don't remember 100% if that had to be activated or just worked)

Despite drowning in cisco and usb-mini cables in the past I purged all the remainders recently.

I have the 7250-48P. It is NOT standard USB. It's serial over mini-USB. I have no idea what would happen if you plugged in a regular USB - I imagine not good things. You can either buy a cable (expensive) or make your own. I made my own to convert RJ45 serial to mini-USB using a RJ45 breakout and a donor mini-USB cable.

This is the breakout I used. Here's some guides on the subject:

And here's my version of it...

Hacked a cable together this evening, the unit boots and displays output to the console but I'm unable to send commands; might be shoddy wiring or perhaps I need to check my PuTTY settings.

For the record, you want to follow the guide on fohdeesha's website dedicated to these switches. Also, it has the steps to unlock 10G and L3 features on the ICX7000 series (ICX6000 series requires a bit more involvement).

As another has said, it is NOT a USB cable you plug into your system. It's a serial cable, using a mini-USB-B connector. Horrible design.

I have a few ICX7250s.

Did you try the USB?

Again, don't do this.

It will fry the serial port of the switch (5V+ applied to a low-voltage serial device.

I added text on how to make your own cable, though it hasn't been merged yet:

github.com

Add 7250/7450 Serial Pinout Details by eduncan911 · Pull Request #5 · Fohdeesha/lab-docu

Putting the serial cable details in one location, easy to reference going forward. Also added some sub-sub-sub ### headers to the Prerequisites area.

I made sure not to use the usb port as a usb port; but I'm wondering if someone else did since nothing transmitted is making it to the switch. I do get output from the device but nothing seems to send to it.

STH has identified 10G RJ45 pluggable SFP+ modules that run at 2.5G in some switches. Is this switch one of them?

In my application, I will use 10G DAC cables to a few servers but want to be able to use a USB-C 2.5G dongle to do the occasional full backup from my laptop.

Thanks.

Added: Found some articles that say to use pluggables with "real" Aquantia NBASE-T PHYs.

It's now working, the first attempt punched down too hard and broke the conductors on the switch bound data line. Looks like we're in good shape!

I don't have any multigig equipment to test this unfortunately; only strictly 10g or 1g.

This router is not compatible with multigig. They don’t have the drivers required to generate the appropriate clocks for 2.5 or 5. Only 1 or 10 will work.
There is more info in the large brocade thread.
