Re: Let me guess...
I hate it when idiots (telco people in my experience) leave a 2/3 unit gaps
I had to do that a while back.
We had 1U rack-mounted kit, but the airflow was side-to-side, not front-to-back. Putting in units at every unit space meant that they overheated.
The recommended way to mount them was to leave a 1U gap between each unit - but if you did that, some monkey would come along and slot his unit in the gap, and you'd only find out when the overnight tests failed because the kit had shut down...
