Thank you for your answer!There are no stupid questions, only stupid answers
The answer is no: stacking can only be done using devices in the same family (64xx, 65xx, 66xx, 71xx, 72xx, etc.)
How does one aquire a license to upgrade the ports ??forgot to mention: licenses for these models are free for existing STH members - now that they are EOL & discontinued I don't really have an alternative to giving them away
It's literally at the top of the first post.How does one aquire a license to upgrade the ports ??
When you cold boot it, does it start out really loud, then the fans spin way down about 2 or 3 minutes into boot? It sounds like it may be stuck in full fan speed, after it finishes booting the fans should spin down to like ~20% of their full boot speedHello all,
Plugged in a "new to me" 6450-24p, and the thing is hella loud. Ordered some Comair Rotron "Gryphon" GDA4028-12BB fans and it's... still hella loud. Pulled the fans out and running them outside the case, it looks like the most annoying part of the noise is the vibrations and the PWM buzz.
I ran across this post (https://forums.servethehome.com/ind...be-40gbe-switching.21107/page-187#post-269342) from earlier in this thred, where a guy used a 330µF to quiet it down. I ran the same test he did briefly, and it does indeed eliminate the PWM buzz.
I've spent the entirety of this evening trying to understand out how low-pass filters work, but I must be incredibly dense, because I'm still just as puzzled as when I started. Based on what I've read, it sounds like you need a resistor and a capacitor to make it work - yet it seems to work just fine with a capacitor by itself.
My question: Does a capacitor, when used in the manner described in that post, have a chance of damaging anything? And if so, and a resistor really should be used, how would one determine what resistor value to use? (and anyone know the PWM frequency on the 6450? I've got a pretty nice (Brymen) multimeter, but the DC frequency function is reading 0hz or 60hz depending when I measure it, and that guy's video show 3khz).
Thank you
No, it definitely spins down. Just the PWM buzz is really annoying, and there's a bit of vibration I'll need to dampen (when I remove the fans from the case and add the 330µF capacitor like that guy did in his first video, it gets very tolerably quiet). PWM buzz is the most annoying part, really. The 330µF quieted it down nicely, but am currently looking for electronic guidance on whether just hooking up the capacitor like that is safe or not - I have a very basic understanding about how different components (capacitors, resistors, diodes, etc.) work, but anything beyond that I have very little understanding of.When you cold boot it, does it start out really loud, then the fans spin way down about 2 or 3 minutes into boot?

The fan is itself an inductor, and can be part of the filter.I've spent the entirety of this evening trying to understand out how low-pass filters work, but I must be incredibly dense, because I'm still just as puzzled as when I started.

@RobstarUSA - Did you ever get around to trying to setup mDNS/Bonjour ? I am interested in the outcome of this as well. It's quite surprising there isn't a good guide here on how to set this up properly on brocade switches. (working reliably, I mean ). Just like @nickf1227 , I can't seem to get it to work. I am however, much less knowledgeable in the space than he his. I have an ICX7250 which is working fine except this issue of mDNS/Bonjour traffic on my network. I won't mind switching to another brand just to get it to work .I'm kind of wondering if the Brocade needed more commands to configure correctly & you missed something & the cisco needed less & was easier to make work. I'm going to try this with a brocade (switching away from a 3945e) and I'll post how it goes. My brocades are a stack of 6610s however, not the 64xx series.
Is there an equivalent for Brocade/Rukus switches?Cisco Digital Network Architecture (DNA) Service for Bonjour is a software-defined controller-based solution that enables devices to advertise and discover Bonjour services across Layer 3 network boundaries
AFAIK there isn't a built-in service to the switch for this. Avahi (common OSS mDNS implementation) has a reflector mode that will repeat mDNS broadcasts across different networks. I have this configured on a host with access to all tagged VLANs I want broadcasts repeated across.@RobstarUSA - Did you ever get around to trying to setup mDNS/Bonjour ?

Oh, interesting the 6610 does support a mixed stack. The 7k series docs are explicit about no mixed stacking.Although this is not 100% correct - Mixed stacks of 6610 and 6450 are possible, for example.
to be fair the 6610 + 6450 mixed stacking is a bit of a misnomer, they stack in the sense of becoming one "unit" that you manage together, but under the hood the icx6450 is just acting as an L2 port extender - anything l3 and above it has to hairpin over to the 6610 master and back for the 6610 to handle, and also of course that means it's not redundant (if you lose the 6610, the remaining 6450 is just going to be able to handle local l2 traffic only and nothing else)Oh, interesting the 6610 does support a mixed stack.
