Power Supply for C9300-24S

Hi, understand that the default power supply for C9300-24S is PWR-C1-715WAC.

Is the switch still able to run if there are 2 x PWR-C1-350WAC as primary and secondary power supply? Or the primary ans secondary power supply must be PWR-C1-715WAC?

 

Thank you!

24S means 24 SFP ports.
The model 750WAC is used to "drive" the power used by the SFP.

What is the consequence if we use PWR-C1-350WAC in C9300-24S? Is the switch still able to be powered on and provide fiber LAN connectivity?

715 is good PSU for 24-S, i do believe this is more of SFP connectivity, so you do not need any PoE device connecting to this i guess.

When you use the Cisco commerce workspace tool (this tool is available for your reseller), you can select 350W Power Supply to insert in both primary and secondary slot (and the configuration is flagged as VALID).

  • This is perhaps the best solution in your case?

I'm not sure why Cisco provide a 715WAC PS by default, the datasheet seems to display 120W max system consumption.

More a SFP consumption is around 1w per SFP regarding this document and your switch is not able to deliver POE.
