They now have a free license for lab/home use though, so pricing shouldn't affect anyone that isn't using it in production

Got it, thanks for the quick answer!

Has anyone ever tried stacking a 6610 with a 7450 using the 40G port? Thinking I might try this but given the firmware version differences, not sure this will actually work. For now both my 6610 and my 7450 are functioning independently of each other and I am using the second 40G port on both...

Looks like there's a problem with your Tx side, there laser current but the optical monitors aren't seeing any power.

If you want some pointers on the fan mod, take a look at my earlier post in this thread, the whole mod is painless to do. My 6610 and my 7450 (see other thread) are both happily running for months now. My PC is louder than my switches now.

To be fair, I haven’t actually measured either of them but with no PoE load the 7450-24 is listed at 75W while the 6610-24 is listed at 120W. Fans are probably non negligible in both cases if you don’t swap them out since they’re > 10w each at full speed and you need a minimum 3/switch.

7450 has lower bandwidth than 6610 but the newer software, lower power, and higher power PoE ports are pretty nice in certain applications. I agree with you that you need to find one that has the modules already otherwise it isn't worth it.

Yes, power for the PSU fan and a wire with the PWM signal back in so that the switch doesn’t complain about the fan speed.

Totally worth it when you have a switch in your office!

OM5 should be better for >100G+ transmission in terms of supported distances. If the price is close may as well buy OM5, it is backward-compatible.

FTLX are Finisar (now II-VI) transceivers, this one happens to be rebranded as QLogic. A quick Google shows that this is a 10GBase-SR transceiver so you'll need LC-LC duplex multimode fiber. Don't buy OM1, like you linked directly, it is obsolete; instead buy OM4 (aqua) or OM5.(lime green).

Final result with a single 140mm 1200RPM Noctua fan and the power supply fan replaced by a 40mm Noctua (both at full speed). Note this I have a couple of 40G passive cables and an RJ45s connected now but no POE being used. Noise level under same condition from same location is approximately 44...

6610 and 7450 24P both are the same fans/power supplies and quite loud. Power supply revision makes no difference to my ears. Can’t speak to the other models but anything that has Delta 40mm 23k RPM fans will be loud.

See the ICX 6610 fan mod thread, basically you scribe and cut an acrylic sheet to size and mount a fan above the asic and/or CPU. I made the fan push air down onto the asic on my 6610 but I don’t think it hugely matters whether you’re pushing or pulling air if you’re not in a datacenter. The...

I wouldn’t be too concerned about it, these rack nuts are designed to hold way more than the weight of that switch.

Since the switch is in your office, if you’ve got the vertical space for it, I would highly recommend adding a large fan above the asic. These switches aren’t hot because they put out a ton of heat, they’re hot because they’re 1RU and they’re supposed to go in a datacenter where noise doesn’t...

I had 2x rev A in my 6610 and 1x Rev C in my 7450. There is very little difference between the Rev A and C to my ears. In both cases the 23k delta fan is whiny and loud even when running at low speed. The only real solution is to make the switch 2 RU as described in the fan mod thread with 2x...

Hey there, I ran into the same problem on my 7450, to run update_uboot immediately before running update_primary otherwise I kept getting the old bootloader after reset. I've quoted my own post below

I am starting a new thread on the ICX 7540 because it is somewhat similar to the ICX 6610 but after opening it up, it is definitely not the same. I have the 24P version with modules for 2x 40G QSFP+ ports and 4x10G ports. The switch ASIC and the CPU are covered by a single larger heatsink...

All done with the 6610 (see above), very happy with the result, it is now humming along in my mechanical room. Now I am trying to find any info on the 7450 but it doesn't look like there is a thread. Has anyone done any fan mods on this one?
