Anyone have a dead 6450 that still had working POE? My 48 port 6450P has a burnt POE board and I need a replacement.

Or I'll sell this 48P switch OR trade for a 24P with working POE. I replaced my main switch with a ICX7250-48P but need something with POE for my garage. Thanks!
Do you strictly speaking need the 10G uplink for the garage, or could you get away with gigabit? 6430s are absurdly cheap these days, so that might be a option. I don't know as I'd try getting one for just the PoE board as they likely don't match up right, but if all you need is power and not throughput...

I plan on keeping it in the basement which is cooler but summers are hot and humid and forced to run a dehumidifier so I'm a little worried.
If I replace the fans, is there a particular brand/model everyone is using?
I run the Sunon KDE1204PKV3-MS ones, I have all 3 in there, and I live in Dubai. It survived last summer where the ambient 100+ F room temp was no problem at all for the switch..

Great post! Thanks for sharing. I've been racking my brain over what switch to get for my new homelab and your post really helped.

I meant to pick up an ICX-7250, but in my tiredness I accidentally bought (and paid for) an ICX-7450-48 for $200 shipped... is this going to be a problem for some reason?

it's a nice switch, but compared to the icx7250 you meant to buy it will be louder, draw more power, and currently only has half the 10gbE ports (4). if you want the 8 ports of 10gbe the 7250 has, you'll have to buy another 10gb module Brocade ICX7400-4X10GF ICX 7450 4-port 10-Gigabit SFP SFP+ Module | eBay

Awesome, thanks. I’m alright with the power draw but hopefully it’s not crazy loud. I currently have my rack in the living room. Spec sheet says 47db so I guess I’ll find out what that means. The 6610 would have been better I think but oh well.

I went ahead and snagged some 40gb qsfp+ cables/modules/NICs since it was reasonable on eBay (~$150 for 3x cards, 3x modules, 2x cables). Hopefully the NICs will work with Promox/Unraid.

It’ll definitely be something to grow into considering I’ve been using an ISP router with a hodgepodge of cat5 and cat5e cables.

Stuff I bought (hopefully I picked this stuff correctly):

Damn you have a wealth of knowledge. Hopefully the seller will modify and I can save a bit. Thanks (again) for the info. :)

Looks like I need to familiarize myself with that doc. I can’t wait to get this stuff installed.

weird limitations like that, costing more than a 6610 with less connectivity regardless of config and a couple other reasons is why I skipped the icx7450 in my main post
Maybe you could add them and mention this (or more generic) - at this point they are common enough that they are cheaply available every now and then and they sound nice if one does not know all the nitty gritty details you do :)

I know it was posted in this thread before; but, I was unable to find it.

Here's the pinout for the ICX 7250 and 7450 serial cable. It's really only 3 soldering points from an old mini-USB cable you may have.

Ruckus ICX 7250 Switch Technical Specifications
^- scroll down towards the bottom

Serial port specifications (pinout mini-USB)
Pin - Signal - Description
--------------------------------------
1 - Reserved - Not used
2 - UART_RX - Receive data by Ruckus ICX 7250
3 - UART_TX - Transmit data by Ruckus ICX 7250
4 - Reserved - Not used
5 - GND - Logic ground

Serial port specifications (protocol)
Parameter - Value
----------------
Baud - 9600 bps
Data bits - 8
Parity - None
Stop bits - 1
Flow control - None


Also, created a PR against @fohdeesha 's github repo so we don't have to keep looking it up.

I finally finished reading this entire thread: I think I clocked around 6 hours. I have numerous notes about what to read next to better understand most of what is discussed here.

@fohdeesha Do you have an Amazon wishlist? I don't have a Brocade switch but I feel I should do something given how much of your time and knowledge you have shared.

I found an extra pair of ICX6610 two-post rack ears while cleaning this weekend. Going to make an official for-sale post later, unless someone here wants to PM me first...

I have a stupid question: Does it make any sense to stack 2x switches that are on opposite sides of a building, or in out buildings? A core switch and a secondary one. As in to be able to admin them both at once since they'd likely share common stuff like VLANs and network settings.

Or does stacking only make sense for uses where the switches are sitting in the same rack, closet or close proximity and serving the same type of general purpose LAN stuff?

Do you strictly speaking need the 10G uplink for the garage, or could you get away with gigabit? 6430s are absurdly cheap these days, so that might be a option. I don't know as I'd try getting one for just the PoE board as they likely don't match up right, but if all you need is power and not throughput...
Thanks for the recommendation! I run a small business out of the garage, so while nothing earth shattering I'd like to keep it 10G to help with moving files around. I'm basically an overkill guy. 10G really isn't needed for anything I do but since I'm going to waste the time and energy to install fiber between the locations, and buy $15 in Brocade SPF+'s, I guess I might as well do 10G lol.

I'll have to see if someone can identify the POE board from a 6430 and maybe it's a match?

That would be pretty cool! But in reality I'm likely better off buying a 24 port POE 6450 off of eBay and trying to sell my 'POE broken' 48 port 6450 instead. I don't need 48 ports in the garage and I never mind saving some power and heat with the equipment.

I know it was posted in this thread before; but, I was unable to find it.

Here's the pinout for the ICX 7250 and 7450 serial cable. It's really only 3 soldering points from an old mini-USB cable you may have.
Cool, good info! Wish I had it a few weeks back. For mine I was impatient and got all McGuyver on it lol.

Cut off mini-USB cable to CAT6 keystone jack to normal RJ45 terminal serial adapter to USB serial adapter to Putty on laptop. It took about 15 mins of experimentation to get the pinout matched 100% but fortunately worked!
