It's a software license upgrade, if you don't have it and you configure the ports as a 10G-fullduplex they will go in a ERR-Disabled state.
On the ICX7xxx series the licences are honor based, so basically you just ask the switch to activate the 10G port says "yes, I'll buy the licence, I promise"; more details in the first page of this thread.
Ah I see, that makes sense. Thanks for the very clear answer!

So far as the proprietary mini-USB to RJ45 cable many of have been knocking around - has anyone tried this Cisco one or have opinions on it? Much cheaper than the options I've seen (short of making our own).

https://www.amazon.com/Compatible-Console-mini-B-Connectors-CAB-CONSOLE-USB/dp/B06XFKJVJ2/
As far as I can tell, the Cisco mini-USB connection has the USB-to-serial conversion happening in the Cisco equipment itself. The linked cable is just straight-through wires -- in reality, any 5-wire mini-USB cable would work. The ICX models with a mini-USB connection, on the other hand, are outputting serial data directly, so you would need an additional USB-to-serial converter in order to plug the ICX into a USB port on your computer. The $30 options on eBay still seem like the best bet if you aren't going to make one yourself (though it would still require a USB-to-serial connection if you don't have a serial port).

Is anyone using the 7150 with 10G optics and noticing packet drops / high latency?

Code:
Ping statistics for 192.168.0.2:
    Packets: Sent = 93, Received = 58, Lost = 35 (37% loss),
Approximate round trip times in milli-seconds:
    Minimum = 0ms, Maximum = 1ms, Average = 0ms
It seems to be happening in a cyclic manner

definitely not, sounds like a bad optic or cabling (or host). I would get rid of the mikrotik from the path and retest to see if the issue goes away

So far as the proprietary mini-USB to RJ45 cable many of have been knocking around - has anyone tried this Cisco one or have opinions on it? Much cheaper than the options I've seen (short of making our own).

https://www.amazon.com/Compatible-Console-mini-B-Connectors-CAB-CONSOLE-USB/dp/B06XFKJVJ2/

as I've stated many times previously, if there was a cheaper cable I would have posted it. the linked cable is just a regular USB to mini cable, which works great if you're plugging it into a USB port, however the serial port on the ICX is....a serial port

Not sure if this is the correct thread to post this... I've installed MCX354A-QCBT (followed excellent conversion guide) on two ESXi servers with similar hardware. One has Supermicro X10SLM-F board, the other Asus P9D-M board. CPUs are also similar: One is E3-1246 v3 the other is E3-1240 v3. VMs have 2 vCPUs and 4 to 8 gigs of RAM depending on the OS type. Running iperf3 tests yields weird results. When I test windows VMs I cannot get over 10G speed even when they are on the same host. When using ubuntu, I get decent speed on the same host, but pretty low when VMs are on different hosts. Any ideas where to look for a bottleneck?


those are incredible speeds for a VM running on CPUs with barely a 10k passmark, I would be beyond happy with that. As for windows, it's notoriously slow virtualized trying to crack 10gbE and beyond speeds, there's a lot of tuning guides out there which can help some. Hell, windows takes a lot of work to really use 40gbE even running on bare metal, especially with CPUs with such a low single threaded passmark. Testing from windows VM to windows VM on the same virt host, the traffic does not even leave RAM, let alone hit a network card or switch, so you can rule out your network. It's just windows being shitty windows

Cool, thank you. Wasn't sure if this one differed somehow.

A major thanks to all your work on this thread. I've been reading it for the past week and it convinced me to make my purchase.

So I received my ICX7450 in the mail. Holy crap this thing is loud and I'm not super sensitive to fan noise.

There's two fan modules that come with it. Pulling out one of them brings it to a bearable level. Will this be alright for a non-POE 48-port?

have you updated to the latest fw and everything and let it fully boot? it should get better, but yeah there's a reason they're not in my original post

For anyone who's trying to sort out how to connect to the mini USB port on the 7xxx series:

I wired up one of these a couple of days ago, it took me about 3 minutes. Pins 3 and 6 on a Cisco-compatible rollover cable are Rx and Tx, you just need to connect those to the white and green wires in a mini USB cable. Rx from the switch goes to Tx on the Cisco console cable and vice-versa.

The pinout on your keystone jack might be different, just wire white to pin 6, green to pin 3 and black to pin 4 or pin 5.

Not yet but I’ll post after doing so. About to hack up a Cisco console cable to see if I can get serial access as above.

Letting it fully boot definitely helped though it was vacuum cleaner loud when it first started.

I'm not super surprised by this TBH, the fan/psu modular system on the 7450 uses the same parts as the 6610 which is on par with a vacuum cleaner during bootup.

Well I couldn't get the Cisco cable splice correct. USB Mini B to Cisco console to RS232 to USB in this configuration: Brocade Mini-USB to RS232 cheat cable! : Brocade my wire strippers didn't work at a wire gauge that small so it could be that I damaged the copper at the splice point stripping them. I had spare cables so I figured it was worth a shot (I don't have RJ45 keystones unfortunately). I could very well have the setup incorrect besides the splice also.



While I wait for my official cables (tomorrow!) I managed to telnet into the switch and update to the latest firmware. Since I can't get to the bootloader and disabling DHCP kicks me off before I can set an IP I'm pretty much playing the waiting game.

With the latest firmware the 7450 isn't any quieter, but with only one fan module and one PSU disabled it's not horrible.

Invest in some 3m gel filled quick splice connectors, they'll make splices like that really easy. Stripping wires that size is a pain, especially when they're stranded and not solid core.

Man I'm having seriously bad luck with a DIY jack. I tried this with a keystone and still nothing. I hope the serial port isn't fried. My serial cable is late because of the northeast weather and I'd really like to get this tested, but so far blank console (Xterm/Putty Windows, MiniCom/Putty Linux). Flow off, 9600 baud, 8 data bits, 1 stop bit.





With the keystone I plugged in a Cisco SERIAL auf RJ45 Cisco Systems Console AWM 20251 E129757-3 LL97744 | eBay stock cable (I reterminated the RJ45 connection), and went directly into a USB to RS232 connected to all different USB ports (2.0/3.0/3.1).

At least I'm learning something new.

Edit:
Yup. The actual 3M connectors are usually better quality but generics work just fine in a pinch.
Ah cool well I picked up some generics as well as the aforementioned keystone (Lowes actually carried some which surprised me). Definitely gotta snag some 3M ones though.



Edit 2:

Well it works with the official cable. I was either doing the pins incorrectly or the Cisco serial was incorrect/bad somehow? Leaving this for posterity in case it helps someone.
