rear rack rails for 6610s for cheap if anyone has some droopy boys Brocade ICX6610-48P-PE Switch Rack Mount RMK Kit | eBay
the proper manual (this thread) has mentioned that a few times it should only happen with rev A power supplies. Rev b and C should happily run at low speed with just 1 PSU activeMy 6610 now runs quiet. I put the other psu cable in. It's amazing.
So looks like it goes into turbo hairdryer mode to annoy the hell out of you until you give it what it desires, power redundancy. That wasn't in the manual, well the manual I read, it came with it for free, just one small page, titled, 'sold as seen, not for idiots'.

Oh I never doubted you, I just thought better safe than sorry y'know. The only reason I care right now is that the 10Gb switch chip gets stupidly hot when it's in use and there's no airflow, the chips near the 1G ports seem totally fine passively cooled.Do you guys believe me now that these things need basically zero cooling at homelab usage levels?
as for the PWM noise, without cobbling a bunch of shit together the easiest thing would probably be just tap off the raw 12V from the PSU and drive a fan with it, and size the fan so the full speed CFM is your ideal CFM/noise (eg a very small/slow fan)
The PWM whine from the 6450 at low speed is the loudest thing in my office when the air filter isn't running. If it's more noticeable than my desktop it goes under the knife until it isn'tTo be fair to... myself... my 6450 is mounted top of a 4 post that holds 'all the tv stuff', in the living room next to the tv, and the rule of that rack is if it's louder than the PS3, it gets the axe or surgery.
Absolutely, at fan speed 2 (full speed) that's all it's doing anyway, getting the full 12v railIf I tap the 12v supply to drive a quiet fan at full speed is it safe to hook the tach line up to the header for failure alerting?
The prices on the dual 10Gb CX3s have started dropping in the last couple of months too. I need a couple more cards and it's tempting at this point to just switch to buying MCX312's and skip the need for the QSFP to SFP adapters. $25/2x40Gb VPI board is a damned nice price, but once you've added on $12*2 per card for the QSFP adapters you're right up into the same price range as the 2x10Gb cards anyway. I don't know if there's much difference in power draw but I'd imagine the 2x10Gb boards are at least a couple W lower than the 40/56Gb model.I just went through all 84 pages of this thread and like Vicious I got the S2500 and would like to check out these Brocades. I have my S2500 working in my lab-lab (not home-lab) with my home config with another FW and am anxious to see what kinds of response I'll get with my CX3s even though I have no need for the extra bandwidth. These switches are at a nice price point, with all the port types I'll need for the near future, compared to the Arista 7050Q/Qx available on eBay. Having worked with the Arista 7060CX2-32S for a project, I've gotten to like them quite a bit.
Thanks fohdeesha for your enthusiasm and generosity in sharing your knowledge for not only these Brocades but the Aristas and other topics in other threads.
If you just want to add redundancy to your dumb L2 switches connection to the stack spanning-tree should do what you want. Turn on 802.1w for the vlan your dumb-switch traffic is interfacing with on the stack and plug your redundant links into different stack switches on that vlan and that should be it. If you lose the stack switch with the currently active link RSTP will re-learn the topology and unblock another link to take over.Say I had a dumb switch (my ISP provided ONT / router / switch device) and a stack of 2 ICX switches. Is there any way to create a two link failover type lagg setup between the dumb switch that doesn't support LACP and the switch stack?
can you link the serial cable you ordered for the 6650? there's some listed on amazon that don't have the right connector (or are just a usb cable)My switch arrived but it did not come with a console/serial cable. Much hunting later and I found some on amazon and they will arrive on Monday. Then i'll flash the 6650 to the latest and go from there.
Overall: The sound is NOT that bad, but I don't have anything plugged into it just yet. No louder than my supermicro servers that I have running in my office and will be quiter once I close the doors to silence all the gear.
Do you have what pinout you did to create this?
Got my 7250-24P today and initially I powered it up without the console plugged in. This unit takes way longer to boot than the 6610 and I thought it was DOA since the fans weren't coming down.
I built a mini-usb to RJ45 so I could use my standard Cisco cable and then I saw that it was in fact booting, it just sits at "Starting Kernel" for a long time before moving along..
Here is the pinout for the contraption I made. Seems to be working well.
