I just got the Brocade ICX 6450-48p from eBay. I am able to log in but can't seem to erase the username and password and factory set-default command does nothing, I cannot confirm it with the command Y. I followed the setup guide and all worked well in the beginning until I went to type Enable and it asked me for a username and password.
if you succesfully followed the bootloader and OS update bits, then you should be able to pull power and clean boot the switch to boot into the latest working bootloader you flashed, then follow this block again

setenv ipaddr
saveenv
factory set-default

I figured it out, didn't set the right TFTP ip address but I can't seem to get the POE to update now, I'm getting TFTP session timed out POE Error: Firmware tftp timeout.

Alright. Its been a hella long time since I took cisco classes in college. I did however manage to follow and get through the setup guide, very well done, thank you so much. This 24Port POE 6610 switch would have been a $160 brick without your help.

That being said I have an edge router mikrotik 305 upstairs for 10G connectivity and breakout for another 1G POE switch for cameras and a pc with a DAC cable. I am using mikrotik S+Rj10 SFP+ adapters to connect the cat 5e run in my wall from the brocade in my garage to my mikrotik upstairs. No dice unless I use a 1G port on the brocade, then it links up likity split at 1G speeds. I cannot get any auto negotiation when I plug the cable from the 1G port on brocade to a sfp+ port with an S+RJ10 adapter. These SFP+ adapters can only use auto negotiate according to their wiki. Am I missing something dumb on the brocade? Do I need to turn on auto negotiate speed for the front SFP+ ports? I do have my unraid server down there in the same rack plugged into one of the front brocade SFP+ ports with a 2 meter DAC cable and it just works at 10G speed when I plug it in automagically...

I cannot run a DAC or fiber cable from my garage where the rack and brocade and server are up to the third floor. I only have the CAT 5e cable in the wall. Its not an easy pull, the previous owner cut a lot of sheetrock holes to wire up the house. I wish I could just use a fiber cable, seems like they give better signal?

Also I may be doing something wrong on the mikrotik switch, in order to get it to link up to the 1G port on the brocade I have to first plug the FSP+ adapter into the 1G dumb switch that is next to it, and get it to link to that. then if I swap wires to the wire going down to the brocade they will connect at 1G speed. If I don't do the cable switcheroo they wont link up, and according to the wiki for these FSP+ adapters you can't just force set them to a lower speed like say 5G or 2.5G, in case they wont talk at 10G speeds. I would hope they just auto negotiate down, but I've waited for minutes with no link up. I also can't deffinitively find out the maximum distance for these FSP+ adapters but if they are 30 meters I should be ok, as its only 40-50 foot distance of cat 5e cable...

I got almost everything working and followed the guide. I'm able to login via SSH. The only thing not working, is that the switch doesn't seem to be working as a regular switch and I can't see the switch listed on my router as a device. Maybe there's something I missed but I'm not too sure what to look for to troubleshoot this.

It's a mini USB port wired for serial. If you connect it to your computer with a regular USB cable, you'll be lucky if it doesn't burn it out.
What do you mean by regular USB? I was going to buy https://www.amazon.co.uk/gp/product/B00NH13S44/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1 as I can't put a DB9 connector in my laptop

Do I need to get something like https://www.amazon.co.uk/Cisco-Cons...ocphy=9050376&hvtargid=pla-570384800065&psc=1

Neither of those cables will work as-is. The first one assumes that the link between the machines is USB, but in this case it is RS-232. The second one would be a starting point, but the RJ45 connector would need to be removed and replaced with a properly-wired mini-USB-B connector.

No, you need:
USB to serial adapter:

A Cisco console cable:



A donor mini-usb cable, then you need to cut the mini-usb and the cisco console cable and join them using the above mentioned pinout:


Code:
Cisco               Mini-USB
------------to---------------
BLACK                GREEN
GREEN                BLACK
YELLOW               WHITE
There are some USB to cisco rj-45 cables on Amazon that would save you a couple pounds, but there is no guarantee that they will have the same inner cable colors as the original cisco one, so you would need to find out which ones are ground,rx,tx and match them to the donor mini usb cable anyway ....

Edit, just to make sure,

PC->USB to serial->DB9 side of the cisco cable ->joint->mini-usb side of the mini-usb cable

Bit pricey with import fees and postage. If I end up getting that https://www.amazon.co.uk/Serial-Fem...ocphy=9050376&hvtargid=pla-1281397864501&th=1 is compatible?

I've never cut cables before don't have the tools for it would rather buy something else that's compatible

According on pin-out published on Amazon, neither of these two cables are good.

But you can build one. Buy these 2 cables (for example):

DB9 Cable on Amazon US - DB9 Cable on Amazon UK

USB Cable on Amazon US - USB Cable on Amazon UK

Now, follow these steps:
1) Cut the USB Type A connector (Pic) and you will find inside the cable, 4 little wires: Red, White, Green and Black (Pic)
2) link the white wire of the USB Cable to the blue wire of the DB9 Cable
3) link the green wire of the USB Cable to the brown wire of the DB9 Cable
4) link the black wire of the USB Cable to the yellow wire of the DB9 Cable

That's it! You will have a Brocade Serial-USB Mini console cable.

Don't have anything to plug the DB9 into. If you can suggest an adapter to go with it to USB that would help (plug USB into laptop/desktop)

It is not possible to connect the mini USB of ICX to a regular USB port on PC, because the mini USB is not a real USB port.

So, after you build the correct cable, you "speak" with the switch in a old serial way, that's why you have a DB9 connector to the other side.

If your PC/Laptop needs a RS232 serial port, you may buy this one:

RS232/USB Adapter on Amazon UK

and use a program like PUTTY to connect to the switch
