M4300-12X12F 24-Port Managed Switch 10G link fails to come up with Intel SFP PN: FTLX8571D3BCVIT1

I was hoping for a non-$300+ option.

Hi sark,

I checked Intel® Ethernet Converged Network Adapter X520-DA2 specifications, and I don't think it should work with SFP+ optical modules (transceivers).

Instead, Passive Direct Attach cables seem to be required for each port.

On the switch side, we should now support any MSA standard-based DAC cable, including our AXC761/AXC763.  But we know that servers are picky most of the time. I would advise you check with your DELL R510 server vendor, and requests the information for approved/certified DAC cables for your new server. This should be the best way to go.

Regards,

Hi,

I know this is an old pors, but just wanted to add some info to help anyone else.

I have the following hardware installed running VMware 6.x, and not experiancing any of the previously mentioned connection issues. Switches are on 12.0.2.12

2 x 4300-12X12F Stack
4 x Dell R810, with 1 x Intel82599EB 10 Gig TN, 1 x Qlogic NetXtreme II BCM57711 10 Gig cards fitted

1 x ReadyNAS 4312
2 x ReadyDATA 5200

All of these are connected together with following SFP / DAC

Fiberstore SFP-10G-DAC (less than $20)
FiberStore SFP-10GSR-85 (less than $20)
Intel Corp FTLX8571D3BCV-IT 10GBase-SR

The FS kit was low enough cost to be worth a try, and I have to say all worked first time, and have seen no issues in production. The mentioned Intel kit was from some legacy kit, so no price known, but all works fine.
