Where can I ask the following?

The Cisco Field Notice: FN - 63697 was first released on 11-Nov-13, advising customers that RJ45 boots "Might Push the Mode Button and Cause an Unexpected Reset on [some] Switches". This caused a recall of those devices, costing Cisco many monies.

Cisco Switch Mode button being pressed by RJ45 boot

Consequentially, the Internet likes to ridicule the designer of this particular device for missing this, however, is it really their fault? Is the boot actually part of the RJ45 design specification, or is it a non-standard addition?

  • If the RJ45 boot is not included in the RJ45 spec, then it would be a non-standard addition. As such, the Cisco design team should be forgiven as they would have been working to the official specification.
  • If, however, the RJ45 boot is included in the official RJ45 spec, then indeed, the Cisco design team should have known better.

I have tried to find a definitive answer but cannot find one. I would be most grateful for your help!

It would appear the closest fit would be Network Engineering under the physical infrastructure (e.g. standard color coding of cables, types of fiber, etc.) criteria.

There are a few questions on RJ45 now.

I’d recommend rewording the question into whether or not the boot is in the specifications and tone down the reference to Cisco failing to account for the boot.

    Thanks. I guess that, while it was the inspiration for the question, the Cisco part is not necessarily pivotal to the question itself. Nov 30, 2022 at 15:17

    I do think that a brief mention of the boot fiasco (or is it ciscasco?) would provide context to the question and explain why the question is worth considering. Dec 10, 2022 at 14:48

The help for our Network Engineering site clearly says:

"Note: All questions about RESIDENTIAL/HOME networking and CONSUMER-grade equipment, are explicitly OFF-topic.".

I think they would prefer that your question require a professional setting, rather than be of a nature where the device could be used at home; even if it's a small business.

While your question might technically be on-topic it could receive a cold reception.

With 26 questions your question is likely to be more warmly welcomed on our Server Fault site.
