Connection 2 PC 6248 10gb SFP+

Did you ever find a solution?

I also have an old 6248 that I'm trying to use the 10GB SFP+ ports on.  In my case, I have installed the 10GE SFTP+ Module in Bay 1 (6200-XGSF w/2xDell FTLX8571D3BCL transceivers).  Bay 2 is occupied by a 10GBase-T module that is working fine.

The client connects fine if I use one of the SFP ports on the front (1/g45-48) so I know the cable (10Gb duplex mm OM3) is good, and the transceiver in the card shows 10000baseT/Full is supported:

Any suggestions?

Hi @chestr,

Could you let us know the module's DPN#? 

Have you already enable the port by entering #no shut?

What is your goal of using the Bay 1 SFP+ module?

What if you swap Bay 1 with Bay 2 module?

The DPN is 0U691D, and the port has been enabled by using #no shut.

console(config-if-1/xg2)#no shut

The goal is to be able to use 10Gb for SAN connectivity.  I have two ESX servers that have 10GbaseT ports which will use 1/xg3 and 1/xg4.  The SFP+ port needs to go to my NAS, which has the FC port.  Here is what 1/xg2 looks like:

As for your last question, I cannot swap the modules as the 10Gbase-T module will not work in Bay 1.  But I have tried the SFP+ module in Bay 2 with the same results.  Also, I have tried two different 6200-XGSF modules, each with it's own Dell branded SFP+ transceivers, in Bay1 and Bay 2, and had the same result with both modules.

Thank you for responding!

Hi, Could you review "How to configure the optimal switch settings for an IP based SAN" from here https://dell.to/3kvACVF might be it helpful.

I'm not sure, I saw "6200series switches support dual 10 Gb slot interfaces. These interfaces can
operate at 10 Gbps when supporting optional SFP+, CX4, XFP, and 10GBase-T modules."  from pg 52 https://dell.to/3wfsifq I don't know what we are overlooking. I checked DPN and it seems okay to me might be transceivers causing that. I'm confused, anyone in the community is welcome to share their experience.

Thanks for replying Erman,

I have previously reviewed this doc and will put into practice some of its recommendations.  But first I need all components to be able to communicate over the 10G ports.  Do you have any suggestions to help troubleshoot the connectivity issues I'm having?

I agree that my issues are symptomatic an unsupported SFP+ but I cannot find a compatibility matrix online.  I would greatly appreciate hearing from anyone who has this working so that I can compare part numbers.

Just to close out my portion of this discussion, I did get this sorted out.  The Dell FTLX8571D3BCL SFPs are NOT compatible.  The SFP+ modules that do work are Dell 407-BBOU.
