Having an issue with this switch.

When I plug my device in it instantly shows

Code:
sw0# 2022/09/17-09:48:20, [NSM-1042], 27922, SW/0 | Active | DCE, WARNING, sw0,  Unqualified SFP transceiver for interface TenGigabitEthernet 1/0/4 is detected.
These cables are 3m (10ft) Brocade 10G-SFPP-TWX-P-0301 Compatible 10G SFP+ Passive Direct Attach Copper Twinax Cable - based off the following I thought they would work? https://cloud.kapostcontent.net/pub...b-3f9e6dd10c51/vdx-transceiver-support-matrix

When I plug the other end into a Brocade ICX6610 I get the following

Code:
sw0# 2022/09/17-09:48:31, [NSM-1003], 27923, SW/0 | Active | DCE, INFO, sw0,  Interface TenGigabitEthernet 1/0/4 is link down.

Can anyone suggest some cheap compatible SPF+ cables need 2-3meter

Bought "10GBASE-CU Passive Direct Attach Copper Twinax SFP+ Cable Compatible for Cisco SFP-H10GB-CU2M" from Amazon but kept showing

"Incompatible SFP transceiver for interface TenGigabitEthernet"
The ones I use are Proline. Not sure if they are even sold anymore.

I can verify that the FS.com 10gb DAC cables for Cisco work on mine. I can also verify that the FS.com 10GB SM optics work as well. I would return the amazon ones and get them from FS. Using 12 DACs and 8 optics and zero problems.

Any options out there on replacing the fans to something quieter ??

I have mine up and running okay - but would love to swap out the fans for a quieter experience.

what are the specs on these things ?

I just bought a pair of VDX 6720s with the port on-demand license so they have all 24 ports active. One came fully populated with 10Gb SR optics too so that saved a ton. The firmware is way off between the two however (fohdeesha just PM'd you) so working on getting that resolved.

I also went through a real ordeal with the 10Gb Intel x520 NICs. They seem to only support two different SFP+ modules but I used NathanA's guide to rewrite the EEPROM to accept unsupported optics and it all works great now. Thought I would share in case somebody else comes across this issue.
Can you do a mesure of power draw and noise on this ? I'm looking at the 6710 as an alternative to the 6450-24 since the latter became stupid expensive lately .

VDX 6470 is probably the most open switch I have used regarding optics.
I can't agree with that :) Based on our experience this is the most fastidious switch... Talking for myself I haven't so many problems with transceivers compatibility, but some fellows of mine had. They told me to be careful before I started buying VDX switches because of that... Even my Cisco Nexus 6001 has command to be forced to be ok with unsupported transceivers, but VDX seems doesn't have such... What I mostly like about VDX 6740 is that they have ISL, and you can spread some switches here and there, link them with more than one link and don't worry about loops, spanning tree etc. they just deal with everything themselves :)
