N2K-C2348UPQ FEX does not come up due to "SDP timeout/SFP Mismatch"

Hi Community,

 

I've recently installed fex N2K-C2348UPQ, but it didn't come UP. The uplink one the 5K switches stuck on "SDP timeout/SFP Mismatch". I've already upgraded the NX-OS to 7.2.1 and reload the fex several times but still the same issue. Below are more details:

 

1/ 5K version:

CXP Microcontroller Firmware:
Module not detected
kickstart: version 7.2(1)N1(1)

kickstart compile time: 10/14/2015 19:00:00 [10/15/2015 06:02:08]

3/ Infra:

 

On the 5K side: Using 10Gbase-LR SFP

On the Fex side: There is a converter QSFP to SFP+ pluggued

FYI: I've tried by changing port on both sides and SFP on the 5K.

 

Currently the FEx is in a "Fabric Up" state.

 

 

 

I'm not sure what other actions can be done, please help.

 

Thank you in advance.

Hi @zizou6500 

Have a look on this Field Notice:

https://www.cisco.com/c/en/us/support/docs/field-notices/639/fn63977.html

 

Cheers,

Hi @Sergiu.Daniluk ,

 

Thank you, I already checked that notice. It seems like the only remaining solution is to manually flash the Fex.
