How to confiugure 40g ICX 7750 with

[Dandy]

Hello,

Can anyone guide me with 40g as I am configuring with Huawei with dac cable but when I loop it has light and when I insert in Huawei switch it shows incompatible.

This is the below information

Hi Dandy,

Thank you for sharing that detail, the reason I mentioned that both the ends should be compatible : is as the DAC when connected on 7750 :

ICX7750-48F Router>show media validation

Port Supported Vendor Type
----------------------------------------------------------------------
1/1/47 No FINISAR CORP. Type : 10GE SR 300m ((SFP+))
1/1/48 No OEM Type : 10GE LR 10km ((SFP+))
1/2/1 No CISCO-OEM Type : 40GBASE-Passive Copper 1m (No t supported) 

We have the part detected, but the same detection raises the not supported warning. 

Hence if we use the GBIC for example : say E40G-QSFP-SR4 [ referred from the document ] 
you would need another 40G QSFP SR4 rated transceiver on the Huawei end : and same should be able to form an connection. 

as here the bits 40G QSFP SR4 are the specification to be matched on both ends,
and once these are matched : rest of the bits should fall in place, with the GBICs from respective Manufacturers,

 Let me know if the suggestion helps,

Hello,
Just to know when I loop the same dac cable on both switch it does get on. GBICs I won't be able to find in the Asian market.

Hi Dandy, 

Thank you for reaching out, 
The issue here is due to the compatibility : 

ICX7750-48F Router>show media validation

Port Supported Vendor Type
----------------------------------------------------------------------
1/1/47 No FINISAR CORP. Type : 10GE SR 300m ((SFP+))
1/1/48 No OEM Type : 10GE LR 10km ((SFP+))
1/2/1 No CISCO-OEM Type : 40GBASE-Passive Copper 1m (No t supported) 


And as the same is a third party cable : we would not be able to guarantee the functioning of the same. 
Hence, suggested the solution of GBICs as that could help you over come this compatibility problem. 

With respect to availibility of the components, do reach out to our sales team, they should be able to help out on that end. 

Do let us know your thoughts on the matter 

Thanks !!
