Did you read/use the upgrade and config guide linked in my OP? it contains a ZIP that has all of the official docs. Broadcom only acquired brocades fibrechannel stuff, ruckus acquired the switching line
Yes, I did.
All the process went flawlessly. Just stopped before "Advanced Configuration" (not enough spare time).
As for the registration: didn't realized the ZIP had all the docs. Thanks again.

Just a little search with the right key words and I can reply to myself: Noctuas? Bad idea it seems

Nope, same honor based lics. I'd like to emphasize to everyone that the v09000 release is a brand new codetrain entirely and a GA release, not even lettered yet. Expect many quirks and bugs, I've already ran into a handful poking around. The WEB UI is certainly....shinier than the old one, I personally don't care for any web UI but I have a feeling a lot of people here (casual users) would prefer it over the old web UI
I guess I didn't realize that the v09 was that new. I will more than likely stick with a version a bit older and tested.

I didn't know that Brocade had been split up like that. I thought Broadcom got it all. I have only ever used the Fibre Channel and FCoE equipment, which brings me to the next question.

Did Broadcom get the Brocade 8000 series? Or did Ruckus get it? It is a great 10Gb switch, albeit a little power hungry. It is also relatively quiet. Of course after having a Dell M1000e in a home lab everything but Force10 is quiet.

Broadcom got that series of FC/fcoe switches including the 8000, yes

Brocade was split in a million pieces, the fibrechannel, fcoe and serveriron (adx) stuff all went to Broadcom who then EoLd almost all of it, the fastiron switching line went to ruckus, and the datacenter and routing line went to Extreme (ces/cer/mlx/vdx)

For my 7250-24P, I started with replacing the rear fans with 2x MF40201V3-1000U-G99. I found that the fans were near silent when running at speed 1, but it would intermittently kick up into speed 2 when the ASIC hit a high enough temp. This sits in a rack right next to me, so I added 1x MF60101V3-1000U-A99 that sits directly on top of the ASIC heatsink and is tapped into the constant 12v to the mainboard, and it never kicks into speed 2 now, even sitting in my rack that runs ~80F inside.
@FozzieBear Do you mind sharing how you tapped into the 12v? I have the same setup, and am trying to get the fan I attached to the ASIC working happily with the others, but am not sure how to go about powering it.

I'm having trouble getting POE to work with the ICX-6450-48P

I updated all the firmware using tftp, everything works, I enable POE for the ports I want (1/1/37 to 1/1/48). I confirm that inline power is enabled:
Code:
 1/1/37    On     Off            0      15400  n/a      n/a         1  n/a
 1/1/38 On      Off            0      30000  n/a      n/a         3  n/a
 1/1/39    On     Off            0      30000  n/a      n/a         3  n/a
 1/1/40    On     Off            0      30000  n/a      n/a         3  n/a

 1/1/42    On     Off            0      30000  n/a      n/a         3  n/a
 1/1/43    On     Off            0      30000  n/a      n/a         3  n/a
 1/1/44    On     Off            0      30000  n/a      n/a         3  n/a
 1/1/45    On     Off            0      30000  n/a      n/a         3  n/a

Then when I plug something in, it gets no power, and all the ports are disabled again. (the something is a pi4b)

Really? first of this very long thread has all the answers.
Really?! First off, I have not used Brocade networking equipment before other than the Brocade 8000. I was simply trying to find out what licenses are required for what switches. This might seem like a simple and stupid question for someone with experience, but for someone that is inexperienced with a majority of Brocade equipment it is a legitimate question.

I have looked through this very long thread and have found no such list of switch to license requirements.

Last time I looked this site is still Server The Home, which leads me to believe that I have the ability to come here and possibly learn a little bit about all things technology. That also includes asking questions when something specific is not pinned in a certain area.

If you can show me where this very specific list is at I am more than willing to admit that I was wrong.

some of these models require license unlocks. PM or email me to request one (they are free and no I am not going to run out).
I may not be a network engineer, but im assuming this means that if the model is listed in the OP, you can pm to get a license

seems like some kind of negotiation error, did you update the poe firmware as well? if I recall the highest power class of 30w requires lldp to negotiate fully, can you try running the following then unplug/replug stuff


Code:
enable
conf t
lldp run

See the first post where @fohdeesha nicely linked to each switch's datasheet? They detail the types of licenses each model needs to activate its full capability. The same is true for all other vendors, not just Brocade.

This fixed it :D

seems like the non-poe+ ports work as well :)

I spoke too soon, 1 of the pis works fine, the others seem to get some power (lights turn on on the pi) but the ethernet lights dont turn on, and it seems like the switch doesn't notice that it should be providing power.

here, port 27 is the one with the working pi, port 34 has a pi with some power(power lights turn on) but no ethernet lights:
Code:
 1/1/27    On     On          4000      15400  802.3af  n/a         3  n/a

I have not tried physically reversing the fans...but...I do know that the fan tray that connects (the two "tandem" fans each), to the switch has resistors in the wire/connector (on the fan side). That's how it knows if you put in a fan tray that's "front to back" or "back to front". You'll have to hack that as well.
Sorry about dredging this up from 3 years ago but I'd like to clarify this point. If you were to buy a 6610 and you wanted to reverse the direction the fans all blow, would it be adequate to just take the fans out of the fan tray(s) and PSU(s) and just turn then physically around? Does it really matter if the switch thinks they're blowing in the original direction? (i.e. is hacking the resistor really necessary?) I get that the control plane's still going to report that everything's "back to front" if I switch the fans to "front to back" without a resistor hack.

Reason I'm asking is it seems that you generally see two different variants of the 6610's. The "E" version which seems to usually come with PoE and just rack ears, and the "I" version which doesn't seem to usually come with PoE but will occasionally come with the 4 post rail kit. It kind of makes sense - a 6610-48-I seems like it would go in a four post rack to connect servers as a ToR use case, and a 6610-48P-E seems like it would be something more used in a comm rack with patch panels for WiFi AP's or other PoE devices.

I don't really need PoE as I have a midspans for that, but would really like the 4 post kit. The hitch is that what best fits my needs (4 post rails, no PoE) is usually the "I" version and I'd like to mount it with the ports forward to patch to the midspan and patch panels to building wiring... which needs the airflow to be in the opposite direction than the "I" version has.

So, as a pretty invested Brocade enthusiast personally and as a network admin who has quite a few in production professionally, I have to once again share my disappointment with the design of the 7450s.

I've been with my current employer for 2 years. In 2016, they purchased approximately 400 7450s to cover nearly all of my sites. Older firmware on the 8070 train were awful, but that aside, there are fundamental hardware issues that plagues this line of switches that I cannot ignore.

Unlike alot of Cisco or HP/Aruba offerings, Brocade has traditionally taken off-the-shelf componentry and integrated them into their products, or they have built their products in a modular fashion. As an example, stacking cables are merely QSFP+ cables, the POE versions of the switches share the same motherboard as the NON-POE versions and have a separate daughter board, the VDX line has 10gig copper versions that report each port as an Aquantia RJ45 SFP+ transceiver.

In terms of the 7450s, I've experienced two common failures that are relatively difficult to detect because they do not generate SNMP traps. The POE daughter board fails, and the stacking cables fail. This year, I've had a dozen of each of these two types of failures across my 40 sites, last year rates were similar. This is about 5% of my total fleet each year.

In terms of POE failures, I will have switches that throw no errors, but will fail to deliver power to half or more of the ports on the switch. Only if I reboot the stack will I be able to coax out some errors, and even then, sometimes I have to actually do a firmware update for the errors to show. Below is an example of what that looks like, again, only after taking the entire switch stack out of production and rebooting it:

A non-healthy switch which is affected by this problem will deliver power to some ports on the switch but not others. Generally, the first 12 ports will work and then the rest wont, or the inverse. In some cases, the switch will even be delivering power to devices but if you look at the inline power table, it will report no devices are even drawing power.

I've also experienced some other oddities with some crappy POE devices that work fine with Cisco or HP/Aruba switches. I have a non-isolated POE hat for my RPI 4s:
1629557381528.png

If I plug my RPIs into a 7450, or a 6450 the Pis power up and work fine. If I plug in a monitor to the RPIs, the entire POE subsystem fails, and every POE enabled port will stop delivering power. POE power will then work for a few seconds, then turn off again, in an infinite cycle. I've not tested this on a 7150, but suspect it to behave similarly. No other switch brand I've tested shares this behavior.

The second problem I have seen involves the stacking cable failures. I'll receive reports that certain computers in a building are not able to connect to the network. There is no information in the logs that indicate anything is wrong. All the ports are up, the spanning tree forward transaction numbers don't report any links flapping, and all stack members show up in the proper configuration like this:

1629557942857.png

However, one of the cables will be working intermittently, so using the graphic above, if the cable going from 1/4/1 to 2/3/1 goes bad It's hard to find the problem. The only troubleshooting that I have been able to do to determine the issue is that devices on switch 1 and 3 will be working fine, but the devices on switch 2 will not be working. When you have stacks as large as 7 or 8, this makes finding the problem difficult at best.

Anyway, I just wanted to share my exciting life with you all, I hope this helps someone someday. For homelab stuff I love Brocade. For small deployments, they are fantastic. For large deployments, please be wary. Luckily, they do have "lifetime warranties" on them, and so far, Ruckus has honored all of our RMA requests once we provide them proof the POE module has failed. We were lucky enough to have decommed a bunch of switches from a site that closed so we have stock we can rotate in while we await the RMAs. However, if this were not the case we would be in big trouble. A 5% failure rate may not sound like much, but the fact is that services are impacted randomly, unexpectedly, and without any meaningful alerts from the switches. 12 failed switches in the past year means as many as 576 devices stopped working for a day or more before we could diagnose and address the issue. When you are talking about telephones and other safety issues, this is just not an acceptable enterprise product.

I spoke too soon, 1 of the pis works fine, the others seem to get some power (lights turn on on the pi) but the ethernet lights dont turn on, and it seems like the switch doesn't notice that it should be providing power.

here, port 27 is the one with the working pi, port 34 has a pi with some power(power lights turn on) but no ethernet lights:
Code:

I did some more messing around, and I think I have a similar issue to @nickf1227 , I can power 1 pi properly with POE
The other 2 just have some lights come on showing it's getting SOME power, seems like its not enough to boot though as they don't connect to the network, and the ethernet connection/activity lights never come on.

if I disconnect the properly working pi, it seems like it all of a sudden has enough power and one of the 2 not-working pis will start working.

Also, I double checked to make sure I have the latest firmware for everything, I installed the 08030u and updated POE firmware as well, just in case
