Thanks! Yes, I'm running my 7250 on 8095d (from your new guide - thank you for that!). Do you happen to remember if the DHCP symptom was that the switch knew about the lease but the client never configured its IP, or did the switch not have a lease for the client at all?

nope, no support for made up PoE implementations. spec only (802.3af, 802.3at, etc)
honestly don't remember, if you search the thread I might have given those details when I was originally reporting it
thats what I thought. thanks. These damn Mikrotik and Ubuiqiti devices using passive POE... oh well
Don’t know about Mikrotik, but Ubiquity does sell 802.3af adapters to handle their wonky legacy devices (like my just-barely-missed-the-PoE-cutoff AC-Lite):

I'm running 08.0.92bT211 - is that good also?
EDIT: I'm running L2 only - no L3 on the 2 stacked switches.
Thanks. Im aware of those...the problem is the 0.5a max current. I run my mikrotik Omni via poe on a pole on my roof and the omni then powers an ubiquiti lbe ac gen2, lbe-lr and a mikrotik sxt. Unfortunately if I used one of those adapters,it wouldn't have enough power to run the whole setup.Don’t know about Mikrotik, but Ubiquity does sell 802.3af adapters to handle their wonky legacy devices (like my just-barely-missed-the-PoE-cutoff AC-Lite):

ICX7250-24 Fan/Temp info!
Hi folks, I've spent some time testing out different 40x40mm fans in my ICX7250-24, with the hopes of finding something quieter than stock but that still keeps the ASIC cool.
The contenders
The testbench
A Brocade ICX7250-24 running FastIron 09.0.00 with a minimal config and no ports connected (except management). A Zabbix VM polls the switch every 15 seconds for chassis temp information (OID 1.3.6.1.4.1.1991.1.1.1.1.18.0, multiplied by 0.5). I let the switch idle until the temperature stabilized, then took the raw data and wrangled it into Excel. Between changing out fans, I let the ASIC cool down to approximately 50-55ºC. For these tests, the switch was laying on a desk, and the room temperature was approximately 21.5ºC. No additional "ASIC heatsink fan" was used.
The results
Clearly the stock Foxconn fan does a fantastic job of keeping the chassis cool (peak 64ºC), albeit at the expense of being noisy. The two Sanyo Denki fans provided adequate cooling; the B3013 (peak 79ºC) was slightly quieter than the G3013 (peak 76ºC), but was hotter by about 3ºC. The Delta FFB (peak 86.5ºC) was quieter yet, but was about 7ºC hotter than the B3013. Finally, the Delta EFB was the quietest of the bunch, but comes in last place at a peak temp of 94.5ºC.
Analysis
If you're looking for a good, middle-of-the-ground replacement fan, the Sanyo Denki fans will suit your needs. There is a slight noise, but they're significantly quieter than the stock fan. I would recommend the B3013 as it is a bit quieter than the G3013.
If noise is your primary concern, the Delta FFB will be slightly audible over room noise or home HVAC, but the switch will run hotter. Under heavy workloads, the FFB may alternate between Speed 1 and 2.
Avoid the Delta EFB, as it does not keep the switch cool enough (in my opinion) to justify the slight reduction in noise over the FFB. It will also very likely alternate between Speed 1 and 2.
Please note that I did not have any ethernet or SFP+ modules connected, so the switch truly was idle during these tests. Your results may vary depending on configuration and interface utilization. This post is informational only - modify your hardware at your own risk!
To connect the fans to the system board, I purchased a 3-pin fan extender cable, cut and stripped it, and connected the leads to each fan as appropriate (fan red to board red, fan black to board yellow, fan blue/yellow to board black). This allows me to fully reverse the fan modification easily by simply unplugging and swapping out the modded fan for the original.
Closing
I hope all of this info helps - please let me know if you have any questions. I will try my best to answer! In a day or two, I will probably select a fan (likely the B3013 or FFB) and rack the switch, so I won't easily be able to perform any further tests or comparisons.
Cheers!

Has anyone tried one of those 4-pin "fan simulators" from ebay, even if you had to jumper the pins to match this? They are cheap enough that I might try one and run 3x Noctuas off the remaining 2 headers
I have no direct experience with the 6000 series. On my 7450 stack I made sure the units all had the same firmware, did my basic config on the unit I designated as the master, then issued "stack enable". It did the rest automatically.
The web interface is shinier and newer, but a lot more limited in what you can do than the old web interface. I have it loaded on a 7150
Per a ruckus employee last month: they do not recommend anyone use 9.0.0.0 unless it has a feature you absolutely need or you use a new icx7850. There are no planned updates/fixes to 9.0.0.0 (a,b,c) and they are going straight to 9.0.1.0. Also configs setup on 9.* will not work 8.0.95* if you downgrade.
This was critical to know, thank you. Backwards compatibility is one of the gotcha's that has bit me in the past.
I haven't gotten deep into switch configuration or performance, but it seems to be working okay. I know that @fohdeesha mentioned that the 9.0.x train was quite buggy in his experience, but I can't say that I've encountered anything with my very basic config.
Here are some photos of the web UI. You'll notice that there are significantly less configuration options - a lot of the "mess" of 8.9x (and previous) firmwares was a big config tree that allowed you to change almost any config item. I don't know if Ruckus is planning on reintroducing some of these config options later in the 9.0.x train. However, from a "I'd like to look at a status dashboard" perspective, it does seem much nicer and cleaner. However, in an enterprise scenario I would expect you'd use an NMS so individual switch status pages may not be super useful.
Anyways, here are some screencaps of the UI:
Hey, I know this is from years ago: Did you end up getting the EPS 1500 as well? I'm looking at direct DC power backup and need the pinout, the connector itself on the switch side is physically ATX 20 pin which is nice.Hello there,
I've had a chance to acquire a Brocade 6450-48 and the EPS 1500 for a bargain (40€ shipping included... Yeah, a french file-sharing company is dumping some stuff). I'm really happy, it's my first entreprise grade switch, and there are two SFP included (1G, no idea what model). Maybe I'll use it as L3 later, but for now my Ubiquiti ERLite 3 is okay for that (and my ISP, Orange, needs unusual setup...).
I updated it to 08.0.30tT311 without difficulties (it was 07 something). The stock fan was a scream, so I replaced it by a Noctua A4X20 FLX, at its lowest speed (3700 rpm). The switch is litteraly silent, it's impressive. I have the "fan failed" error, but I don't mind.
Temperature is okay, sensor B 48°, sensor A is 60°.
Talking about sensors, I have a question : what corresponds sensor A and sensor B ?
Do I have to worry about the sensor A, as it displays warning and shutdown levels, but not sensor B ?
Thank you !

The thread there states one needs to flash to a non-UFI image then upgrade. Is this true or is that a typo and one needs to flash to UFI?
Must be a typo, you can upgrade from the UFI firmwares to 9, same as going to 8.0.95. I went directly from 8.0.95 to 9.
I think the issue for this poster was that you have to jump in with both feet on 9.0*, both primary and secondary boot need to be 9.0* can't keep 8.0.9* on the secondary.
