10GB SFP+ port compatibility

[GabsC2]

Good day,

   I'm seeing the SBS350 24P + 4 x 10GB SFP+ port and I don't see anywhere if I can connect a 1GB SFP to the 10 GB SFP and it will work. I read some online information and it says it should but I don't know if I can find some documentation that can confirm that it will work or if someone has tested it before. If someone could clarify my that the 1GB SFP will work on the 10GB SFP+ port of the SBS350 24P + 4 x 10GB SFP I'll appreciate it.

   Thanks!

Hello @GabsC2,

CBS350-24P-4X support only 10G interfaces with SFP+

CBS350-24P-4X

The datasheet for this model states that it supports 4x10G. You should confirm this with the vendor or your Cisco sales rep, 'cause sometimes the datasheet may not provide the correct informations.

Thank you for your answer M02@rt37 ,

    I saw the datasheet and it says only 10GB SFP+, normally when it admits 1 and/or 10 it says 1/10, that's why I have the question of compatibility.

@GabsC2 normally SFP+ using 10G transceivers. if you want 1G speed, you can connect 1G transceiver.

As you said @GabsC2, only 10G SFP+.

I just talked to the Cisco Sales Manager and they confirmed that I con connect a 1GB SFP into the 10GB SFP, they're compatible. Thank you all for your answers and support.

You're welcome.

Thanks for that feedback @GabsC2.
