Just for kicks, I tried this with the ICX7250-24. First, I placed the slower Sunon fan into the unit but it caused the unit to go into a boot loop (any slower fan that I tried did the same). The unit would do the high speed fan startup but when finally going to the slower running speed, it would sit for a few seconds and just reboot (over and over and over again) With that in mind, I recplaced the Foxconn fan with the Nidec that I pulled from the ICX6450. It was noticeably quieter and moved less air than the original 7250 Foxconn fan but was much faster, louder and moved far more air than the Sunon. Just monitoring from the WebGUI, the temperature was over 20C LOWER with the fan blowing in than exhausting. 62.5 vs 85.9C. The fan blowing actually blows across the CPU heatsink of the switch (at least in the case of the ICS7250-24). I cut the fan guard from the back of the unit as well. That was responsible from another 2-3C drop (I suppose more airflow into the case).
I also tried a fan controller on the Foxconn fan. I could turn the speed down (and noise too) on the initial high speed startup but the fan would quit when going into regular slowdown mode no matter the dial setting. At that point, the switch would simply reboot starting the whole process over and over and over again. I guess the voltage was too low to run the Foxconn fan.
Sounds like they added a sanity check for minimum tach, probably due to aging. (Some of these fans as they age, will spin slower due to increased resistance before failing.) Or because of us. Either or. Could also be because of changing ODM parts.
Obviously could always throw a multiplier on the tach line, but definitely not a great idea, because that would prevent ramping under load. ("I expect a max 15k RPM, fan says it's at 16k, so don't give it more because of overspeed!") If we can figure out the minimum, I can probably find some alternative parts.
Well I somehow managed to find not one but two DAC cables that will not work on either an ICX 7150 or an ICX 6450, I thought I would leave the info here so others avoid making the same mistake. The switches do detect the modules, they just do not link.
This DAC is marketed as a cisco compatible part, I could not get it working with any of the ruckus/brocade switches I have. I was able to get it working for directly connecting two Intel X520 adapters. Below is the dump of the module using ethtool.
Lastly is a cable that I have been using for some time and it has been working in practically everything I've got. They were included with my connectx-2 cards a while back so I don't know much about them.
If anyone has any recommendations I am looking to pick up a few extra cables 0.5M, 1M, and 5M, I do use optical but I would like the DAC for troubleshooting and flexibility purposes. For instance if I order on FS should I be getting brocade compatible cables or Cisco being that I do have that one cisco-tyco cable that works fine? I was thinking of going with these Cisco SFP-H10GB-CU3M 3 Meter 10G SFP+ DAC Twinax Cable 37-0961 MNPA19-XTR | eBay
Alternatively if there is a way to recode the modules, I'm all ears. I saw how Fohdeesha did this with the monoprice qfsp cables but that was on an ICX6610 which I do not have access to. I know this can be also be done with specialty hardware such as a Revelprog EEPROM programmer with sfp adapter as well but I didn't think it was worth the cost for what will possibly be a one time use.
Shameless plug: I have 8x new Brocade branded 3m DAC cables that I'm not using. Reasonable offers considered. (These are Brocade parts, will show extended info, like temps, with Brocade switches)
Can someone please help. I have just updated my 6450p with the latest firmware for the system as well as POE. It is operating well so far with the limited testing I have done. I cant figure out why POE is not working on the switch yet? I have followed fohdeesha's instructions fully.

one more thing... anyone got a set of rack mounts for the 6450 the want to sell or send me the dimensions too? That would be AMAZING!
Please and thank you
Can anyone comment on whether any of the "Cisco Compatible" rack kits will work with the 6450-48?
Can someone please help. I have just updated my 6450p with the latest firmware for the system as well as POE. It is operating well so far with the limited testing I have done. I cant figure out why POE is not working on the switch yet? I have followed fohdeesha's instructions fully.

Absolutely not necessary, you can enable PoE on just some ports and not on other, that aspect is fine.
Your configuration and the "show inline power" looks good to me, and all that it's necessary really is to enable inline power on the desidered interface(s).
What devices are you trying to power using the 6450? Keep in mind that those switches are 802.3af (PoE) and .3at (PoE+) compliant, so they will source +48V along the pairs of the ethernet cable only if they sense a PD (Powered Deviced) connected; if you plug a "passive" +24V """PoE""" like an external radio or some cheap cameras, they won't pass the PD detection, and thus no power will be delivered.
Rack ears for the 6450 is just a piece of bent sheet metal really, there's not much to it...
The center of the holes is about 11mm from the internal edge (the one touching the frame of the switch), the rail facing lip is 20mm long total (from switch frame edge outwards), and they are 2mm thick.
On mine theres a number written: "B425.00139.015 Rev.00 FOXCONN"

Have you verified the ports you tried these in on your switches are licensed and configured for 10gbE full duplex, eg they link without an issue with other DACs or other optics? Or are these the first things you've tried in these ports? I ask because I've literally used fibrechannel optics in these things, they simply don't care. I'd be surprised if it was indeed the DACs

your config is correct, like infomatt said it looks like the switch isn't seeing any PoE compliant devices on the other end. Note: ubiquiti 24v and other "24v passive PoE" crap is not standards compliant 48v PoE, and will not work with PoE switches without an adapter
Ok I'm just an idiot and have been doing this so long I'm forgetting things, my original 7250 post/notes indeed point out the hardware watchdog and the fact at least one fan needs to be plugged. It would be good if we could pinpoint the rough rpm fans have to meet in speed 1 to not get tagged as failed https://forums.servethehome.com/ind...gbe-40gbe-switching.21107/page-47#post-208624
The ICX6450 will tag a slow fan as failed but will still boot and run. The ICX7250, at least in my case, will tag it as failed and shut down (actually, it will restart over and over and over again....).
