Delta Networks ET-DT7024 24 Port 10GB SFP+

[pepperoni]

I bought a Delta Networks ET-DT7024 24 Port 10GB SFP+ 4 x10GBase-T Layer 3 Switch with Dell PowerConnect 8024F firmware 5.11.1.1 which is working as expected. I use it with 10G DACs, but have a need to use fiber because of range. I have 3 different types of FS.com recommended 10G SFP+ transceivers and cables.
331-5311
E10GSFPSR
407-10356
several OM3 MM LC-LC fiber cables (10M)

When I try to set it up on the Delta Networks ET-DT7024 , it doesn't recognize any of the SFP+ transceivers. No lights and tried several ports. I've checked several pdfs and online advice, but still no luck.

I also have a Quanta LB6M (the Delta replaced it) that I tried with the transceivers. It works by just plugging the transceivers in to any port, so I know the transceiver and cable are working.

I know I'm doing something wrong, but haven't figured it out yet !

A Delta switch flashed to Dell firmware will want Dell transceivers. However, not all Dell transceivers work in the 8024F. I purchased some genuine Dell dual-rate ones and the 8024 didn't recognize them. Apparently they only work in some other type of Dell switch. You should get something like this:

Having said that, the Dell RK0CX which is definitely supported cross-references to the 331-5311 number you gave above, so it should work.

Are you trying these in the SFP+ dedicated ports (1-20) or the shared ports (21-24)?

It is also possible that it is a CPLD incompatibility, though I would think that whoever cross-flashed the switch took care of that. From a privileged session on the console serial port (it won't work over the network) enter "dev cpldTest":

Note that it is normal to get the "Fan control IC has failed". Check your CPLD revision and make sure it is 6. If it is not, contact whoever you bought the switch from and confirm it is OK to do "dev cpldUpdate". It is safe on a real Dell switch, but I'm not sure about cross-flashed Delta units.

"dev cpldTest" also tells you (at a much lower level in the switch) if it thinks it has an SFP in each of the ports.

@Terry Kennedy ... Thanks for info, here are my results from the fiber-port optical-transceiver command. I received the same results from all three brands of transceiver.


Concerning the dev cpldTest command, I used a cable as you suggested. The results look similar to yours, I was using port 1 for the fiber-transceiver. Looks like my CPLD is revision 6. Just as a note , I used several other ports to check, same results.

The computer on the other side of this fiber cable has a Intel X520-DA2 and works with any of the transceivers that I stick in when I change the switch to a LB6M. Everything works as it should. I believe you could stick a fork in theLBM6 and it would work, very forgiving.

Thanks for you help

Just as a follow up on working SFP+ transceivers for the Delta Networks ET-DT7024 24 Port 10GB SFP+ 4 x10GBase-T Layer 3 Switch that has been changed into a Dell PowerConnect 8024F running firmware 5.11.1.1. I finally found a SFP+ transceiver that works, FTLX8571D3BCV-IT.
