I've been looking at the 6450-48p's on ebay. How hard is it to get a license for the 4x 10gbE?

 

Not hard at all.. Start on page 1 of this thread and start reading is all thats required.

 

I have no clue, it doesn't list a pinout. it could be connected a million different ways internally. if you want a cable that is guaranteed working (but costs more) just look on ebay: DB9 Female to USB Mini Serial Console Cable FOR Brocade switch ICX7750 1.5METER | eBay

 

most 40gbase-SR4 optics are rated for 125M of OM4 no problem, I'd imagine if you have good optics, fiber, and clean it properly beforehand 140m wouldn't cause a lot of issues

if you go over that or use worse fiber and you get connection drops, it depends how you've cabled it. stack members should be connected with 2 runs (like a ring), so if it loses one connection it just fails over to the other. If you lose both links then obviously you'll get some packet loss to destinations on that switch, and if they both go down for longer the stack member will eventually be counted as lost until the stack master sees it again

 

thanks alot ， i found very similar cable that you list on taobao https://m.tb.cn/h.enWCWe4?sm=d6044c , btw if cable wrong what is the worst result, just not work or it will fry the port?

 

I doubt it would fry the port

 

Oh , that’s terrible , buy brocade cable or diy cable seems only way

 

I think you misunderstand me - I said I DOUBT it would fry the port - it will probably NOT fry the port

 

ok thanks then i will give it a try when 7250 arrival

 

Ok, so i guess, connecting a 6450 in a mixed stack connected to two 6610 using a regular 10GBase-SR optic over 140m mm fibre will work, im planning to use original Brocade transceivers (does it make any difference where the transceivers were made ? Malaysia or China ?). I hope my fibre is made of good quality, had no problems on our last lan event using that cable with LAG. I'll give it a shot, i mean, if there are going to be any problems, i would see them right away, right ?

 

Just scored an ICX6450-24p for $150 shipped on ebay.

I'm excited to get it and play around with it.. it does seem to have the QR code sticker that I have seen mentioned here a few times:

Finally jumped in with an ICX6100-24F from ebay. Price was right, but its single PSU and FANTRAY are mismatched. turns out I didn't save all that much having to buy a 2nd fan with the right flow.


..CPSS DxCh Version: cpss3.4p1 release
FATAL MISMATCH: Atleast one PSU and FAN FRU should have same air-flow direction!!!
PSU fan air-flow direction: FRONT-TO-BACK!
FANTRAY fan air-flow direction: BACK-TO-FRONT!
System is shutting down!!!
Rebooting(0)...

Good news is, I was able to flash the latest firmware.

Ask the seller for a partial refund or the correct fan tray, as in this state the product can't work... unless it was sold as non-functioning/for parts...

 

I have came up with an idea to use my 6450-48 to connect fibre from my ISP (I have a /27 subnet) on a vlan (6 ports or so) and then connect it to the virtual pfsense, and out of that to the other vlan on which all other 42 ports of the switch will be. Taking care that is no routing between these two VLANs, is this safe to do - or not recommended at all?

 

Sure, it's safe as long as there is segmentation between the VLANs.

 

Does this not open up the switch to the internet? How to make sure I will not get the ssh/webinterface etc on wan, but on lan only

 

If you don't make a VLAN interface on the WAN VLAN you won't open anything to the net.

 

Cool

 

I got my icx6450-24p today, but my console cable won't be here until next week.. I take there is not really anything I can do until I get that?

A fan mod is definitely in the pipe for this thing,, I think the fans may actually failing as they have more of a high pitch ring than I was expecting.
