X540 T2 card connection issue with Ubiquiti switch

[TChen70]

Hi,

I just bought a X540 T2 card and trying to configure network connection with ubiquiti switch but the network speed only running at 1G not 10G.

I wonder to know is there any settings need to be changed at X540 T2?it's my first time using intel network card so I may have missed something here....

Thanks for help

Hi TAChen,

Thank you for posting in Wired Communities. Please make sure the port setting on the switch has the same setting as the NIC's port. e.g. for the Speed and duplex setting under the Link Speed tab, if you configured it in Auto Negotiation mode then the switch should be set as Auto Negotiation mode as well. Can you give the exact model fo the ubiquiti switch as well? Regards,Sharon

Sharon,

Thanks for quick reply...

Yes it's already in Auto Negotiation mode.

Issue description: The connection start at 10G then after few (seconds/mins) it downgrades to 1G and never back to 10G

Model: Ubiquiti Edge Switch

I also have a Broadcom 10Gbase-T card and it does not have this issue so I assume it's relate to firmware issue?

Thanks

Hi TAChen,

Thank you for the information.What is the exact model of the Edge switch? Is it a 10 Gb switch ? https://dl.ubnt.com/datasheets/edgemax/EdgeSwitch_DS.pdfWhat is the operating system used? Please use the latest driver. Have you tried also forcing the speed? Please feel free to update me.Thanks,Sharon

Sharon,

Please see my reply below

What is the exact model of the Edge switch? Is it a 10 Gb switch ?

https://www.ubnt.com/edgemax/edgeswitch-16-xg/ https://www.ubnt.com/edgemax/edgeswitch-16-xg/

What is the operating system used? Please use the latest driver.

Windows 7

driver version: 3.9.58.9102

Have you tried also forcing the speed?

Yes, it works.

But it takes a long time(1 min or or even longer) to force the speed at 10G, is anything wrong here?

Thanks

Hi TAChen,

Thank you for the update and glad the speed works now. Have you tried upgrading your switch firmware? https://www.ubnt.com/download/edgemax/edgeswitch-16-xg (note: this is third party website, we have no control for the content therein). You may contact the Ubitiqui switch support to check. When you said it takes long time to force speed at 10 Gb, are you referring after you forced the speed in the advance setting, you have to wait for one minutes or more to take affect?Thanks,Sharon

Sharon,

Both Ubiquiti Switch and Intel X540-T2 are latest FW.

When you said it takes long time to force speed at 10 Gb, are you referring after you forced the speed in the advance setting, you have to wait for one minutes or more to take affect?

The 10G link is not stable even force it at 10G, sometimes link is up after 1 min or more, sometimes link complete disconnect....

Thanks

Hi TAChen,

Thank you for the clarification and information. Please help confirming the following:1) Do you have another switch model in which you can try to test if the same issue will occur if you connect to other switch? Trying to isolate if the issue occurred only on this Ubiquiti switch. 2) Just to double check if you are using Cat6A or Cat6 cable. Please ensure cable length of 100m if using Cat6A or 55m if using Cat6. 3) Is this the PROSet version you downloaded? version 22.6 https://downloadcenter.intel.com/download/18713/Ethernet-Intel-Network-Adapter-Driver-for-Windows-7-?product=58954 Feel free to update me.Thanks,Sharon

Sharon,

1) Do you have another switch model in which you can try to test if the same issue will occur if you connect to other switch? Trying to isolate if the issue occurred only on this Ubiquiti switch.

Yes, it's same symptoms on my 3 switches(same model)

2) Just to double check if you are using Cat6A or Cat6 cable. Please ensure cable length of 100m if using Cat6A or 55m if using Cat6.

Sure, it's shorter than required

3) Is this the PROSet version you downloaded? version 22.6

Yes, I'm using this version.

Thanks

HI TAChen,

Thank you for the reply. Do you have another brand and model switch to test? Please share the serial number of the NIC, this can be found on the white sticker on the physical network adapter (12 alphanumeric + 5 alphanumeric + 6-3 digits) Thanks,Sharon

[TChen70]

Sharon,

Unfortunately I only have these three.

By the way, I did google search and it seems like the switch phy controller is broadcom, that's why I still think it's a compatibility issue...

Hi TAChen,

Thank you for the information. Based on the serial number the part number G35632-xxx is not an Intel retail network adapter but an OEM version. Intel X540-T2 bears the part number G45270-, you may refer to link at https://www.intel.com/content/www/us/en/support/network-and-i-o/ethernet-products/000005612.html for reference. You may want to check with Ubiquiti support if they have compatibility list for the network adapter supported on their switch since you mentioned the PHY controller is Broadcom. Since this is an OEM NIC, please contact the OEM NIC vendor to further check with them as OEM NIC is best support by the OEM vendor. https://www.intel.com/content/www/us/en/support/network-and-i-o/ethernet-products/000006628.html?wapkw=oem+network Hope the information clarifies. Thank you. Thanks,Sharon

Hi TAChen,

Please feel free to update me if you have contacted your switch vendor, any further inquiries? Thanks,Sharon

Hi Sharon,

Sorry for late reply, I purchased an Intel retail version of X540T2 last week and the problem has been solved, I think different versions(intel retail higher price vs OEM lower price) bring different qualities in this case...

Thanks

Hi TAChen,

No worries and glad you were able to find out the cause by using an Intel X540-T2 retail version. Thank you for sharing the information.Regards,Sharon
