Change Summit X670 / X670V air flow direction

Rowan_Sakul — Wed, 20 Jun 2018 08:28:00 GMT

Hi, I wanted to know whether we can change the air flow direction of the original Summit X670 / X670V (G1) series of switches by replacing both the fan modules and power supplies, much like you can with the 670-G2s.

I'm a little cautious as the Data Sheet lists specific base SKUs with air flow direction:
17101 Summit X670V-48x-FB
17102 Summit X670V-48x-BF
17103 Summit X670-48x-FB
17104 Summit X670-48x-BF

Regards,
Rowan

Yes, that should be okay, but the airflow direction of all the modules must match, for example, the switch, PSU and Fan must have the same airflow direction.

Thanks Sushruth, that all makes sense.
However, before we commit the dollars, I was hoping Extreme could turn the "that should be okay" to "this is supported"!

"This is supported" and documented in the HW installation guide as well:

https://documentation.extremenetworks.com/summit_16/summit_family_hw_install/switch_ovrvu/c_summit-x...

All five installed fanmodules must be of the same model, so that they all direct the airflow in the same direction. Twopower supply bays accommodate either AC or DC power supplies. Power supplies have integratedcooling fans that operate independently of the switch fans. Like the fan modules, the power suppliesare available in models with either front-to-back or back-to-front cooling airflow

NOTE
Air must flow in the same direction for all installed fan modules and power supplies in a switch.

Great thanks Kawawa.
I'm guessing that "All five installed fan modules must be..." is a typo? I'm pretty sure there is only three.

Good catch, Rowan! Yes, "All five" should be "all three." I'll fix that in the next update to the doc.

Regarding the part numbers, those are bundles that ship with the proper fans for the indicated airflow. Swapping those out (along with the PSU) for a different direction isn't a problem.If you end up needing to RMA the switch, you may want to mention that you've made this change so that any replacement parts can be sent with the correct direction.

Thanks guys, I think this one is well truly sorted!
