ICX 7750-48F Copper RJ45 10/100 Compatibility

[byrd23]

Hello,

For an ICX 7750-48F switch, and I would like to connect a copper / RJ-45 device that can only operate at 100 Mbps.  With a 1G M-TX SFP in place, issuing the "speed-duplex 100-full" command results in a response of "This speed setting is not applicable to port...".  Is there any way to connect a 100 Mbps device to this switch?

Thanks.

Hi byrd23,

Thank you for posting your query !!!

I understand you would like to connect a copper/RJ45 device that can only operate at 100Mbps to ICX 7750-48F switch
with a 1G M-TX SFP in place .

It seems 1G M-TX SFP is not supported in ICX7750-48F model.

You can refer the below screen shot for your reference.

You can also refer to the below link for the optic data sheet for your reference.

I'm using the E1MG-TX, which is supported, but the question is different:

Is there any way to connect a 100 Mbps device to this switch?  Does any SFP/SFP+ support 100 Mbps over copper / RJ-45 for this switch?

According to the datasheet, no. The 48f variant does not.
