XGS1930 2.5 Gbit/s with SFP+ RJ45 Modul possible?

XGS1930

Is it possible to connect a 2.5 Gbit/s client to one of the SFP+ ports (with a RJ45 10 Gbit/s Modul) and get the full 2.5 Gbit/s, or are only 1 Gbit/s and 10 Gbit/s possible?

Hi @Tzunami ,

We have tested your case on our site, and the results confirm that it is possible to connect a 2.5 Gbit/s client to one of the SFP+ ports using an RJ45 10 Gbit/s module, our SFP10G-T, and achieve the full 2.5 Gbit/s speed.

However, based on typical usage scenarios and specifications, we recommend using the SFP+ module for uplink to use its 10G capability.

FYI: Please note that the XGS1930 web GUI will display 10Gbps - the data link speed between XGS1930 and SFP10G-T.

Hi @Tzunami ,

You can find the minimum power consumption for the XGS1930 series in the datasheet. For instance, the minimum power consumption for the XGS1930-28 is 12.4 watts. You can refer to the datasheet here:

I have a second question.

What is the min. power consumption when simply running the XGS1930 (no connections, no SFP+ Modules)? I only found the max. power consumption of 24.6 Watt.

Thx, I have read an older datasheet without this data ;)
