Hi Patrick, :-) You have to take care about the airflow, especially in very close future we would have as usual at least 27 °C in cold aisle, … (ASHRAE for DC) An empty 1u below the rack(s) switch will permit to insert air deflector, fan,… etc If you will try to free one U at later stage, you beautiful cabling will be discarded and the uptime of the service will decrease drastically
My two cents on this post Patrick Le 5 août 2016 à 19:31, Patrick Studer <[email protected]> a écrit : Hi Thanks for all the input. Unfortunately, my questions seems not to be clear enough. I know, how to solve the issue. I just wanted to know, if anybody is strictly following the best practice for the airflow or if some ignore the best practice in place for a proper cabling (and perhaps just leaves an additional U free for airflow)? Or in other words, which option count more (better airflow vs. nice/easy cabling).

The easiest solution, if there is no fancy (i.e. software controlled) way to reverse fan flow: Just open the switch, unscrew the fans, turn them around and remount them. Our network engineer did that countless times, and it always works. No need to spend heaps of $$$ on hardware with the "correct" flow direction. _______________________________________________ swinog mailing list [email protected] http://lists.swinog.ch/cgi-bin/mailman/listinfo/swinog _______________________________________________ swinog mailing list [email protected] http://lists.swinog.ch/cgi-bin/mailman/listinfo/swinog
