Hi,
I have a question about the SFP/SFP+ modules on the 3750X switch stacks.
Is it possible to use all 4 ports as 10Gb at the same time or will it be reduced to 1 GB for each port?
Thanks,
Waqas

You can use only two 10Gb at a time in the module. If you prefer 1Gb, then you can use all four. You can use one 10Gb and two 1Gb as well.

The interface for all four 1Gb and the two 10Gb are in the config even if they are not used. Refer to Table 4 in this link.

You can't use RJ-45 10Gb. Purchase the Twinax, it's substantially cheaper.

Thanks,
The reason I ask is because I am using the 2 of the 1Gb SFP but the TenGig ports show as down down. I was wondering if it was possible to use both at the same time.
Also, is it possible to use the 10Gb ports with an RJ45 connector?

**You can use 10G-T if you have that specific module
