@GRL this is what I said. This does not prevent the module from connecting to a device at 2.5 GE. I connected several and after a few steps they all worked. A 10 GE port can carry traffic at 2.5 GE....

@GRL I don't agree with your statement. There are two negotiations that occur. The first is the port and the module, then the module negotiates with the device. I was able to get the 2.5GE devices...

@GRL I'm looking for 8 port 10GE switches to simplify my network. I have a lot of devices, they move around, I don't want to have to move switches as well. I don't want to think about switches. I...

@Vincent-TP yes, I missed the fine print. I've used other vendor products for many years, and never run into this 'limit' on SFP+ RJ45 modules before, so did not go looking. How hard is it to make a...

@GRL I found that the only way to get 1GE devices to work with this switch was to change the port to 1Gbps. You might think that the SFP+ RJ45 10GE module negotiates in the correct order but it does...

@Hank21 thank you for your comments. I've worked around this matter quite a bit. The problem is with the negotiation that occurs when the switch is started or when computers are added. I've...
