Finally caved on an ICX6450-24p.. amazing piece of kit that will replace my mixed ubiquiti + CRS305 setup. Love ubiquiti but hate the direction, so I'm glad to replace everything with this.

There's 1 left if anyone else is looking for a 24poe Brocade ICX ICX6450 24P Gigabit Switch with SFP+, rackears, | eBay

They went down to US$150.. going by sold items, it's pretty on par for sold 48poes but still way less than current listings -- a decent deal. GSP shipping to Canada was actually pretty reasonable (compared to some others that are $100+ lol) so I caved.

Maybe a stupid question but I’m curious and will ask anyway for the sake of learning.

I initially tried some FS transceivers for a 10gBase-T to my workstation over a ~30-50m CAT5e run and it didn’t work. Before deciding to order a spool of Cat6a and add a run I saw they had a 50m (which i ordered) and then saw a 80m model. Took a shot at it working before dropping 250 on a spool and to my surprise it works perfectly. Getting 600mbps transfers to my NAS.

My question is what makes the 50m vs 80m transceiver work? Better build quality or does the 80m utilize more power? They look identical to me—just curious how this works? Thank you for the knowledge!
It's a bit of a mystery what the difference is but since FS says the 80m will not work on Cat5e and needs Cat6a my guess would be it is just receive sensitivity and maybe more efficient chip set with lower power consumption to output. The extra shielding on the Cat6a would provide a cleaner signal over distance with the same amount of power. I have read multiple people say that they are compatible with each other as long as you do not exceed the shortest length so you can use a 30m at one end and 50m, 80m or 100m at the other as long as your cable does not exceed 30m. That tells me it is the same frequency and pairs.

I have a question, I need 3(or 4) 40Gbe ports. Would stacking 2 ICX6610 result in 4 x 40gbe ports or just 2, using the other 2 40gbe ports for stacking? To be more specific, can you use the breakout 40Gbe ports for stacking and get a more than 10Gbps stream between switches

looks like bad flash, but you can try re-flashing the firmware from the bootloader and see if that fixes it:

Code:
#plug the management ethernet port into your network
#drop into the bootloader
#give the switch a temporary IP

setenv ipaddr 192.168.1.50
setenv netmask 255.255.255.0

#tell the switch the IP of your tftp server:
setenv serverip 192.168.1.51

#tell it the name of the OS firmware file:
setenv image_name  SPR08080e.bin

#tell it name of bootloaader file:
setenv uboot  mnz10114.bin

#flash the OS:
update_primary

#when that's done flash a new bootloader:
update_uboot

#when everything is done reboot the switch then follow the regular guide:
reset

There are some NAND commands to erase the chip and even reset the bad block list (scrub). Seems like you haven't got anything to lose at this point. But since it's a timeout error, the chip might very well be completely dead.

Thanks! I’m not sure why either but I’m getting rock solid 10gb performance on my CAT5e cable and pushing my cache drive to the limits. No complaints here!

The 80 meter cat 6a only part is ~2.5 watt power. The cat 5e+ version is ~3 watt max. Spec sheets are on their site for each.

Yeah I just looked more closely and see it (missed it before). Still shocked it’s working over Cat5e and performing remarkably well! Thanks!

OK. I've been through the thread and can't find an answer. I apologize if I've missed it.
What breakout cables do you use for the QSFP+ ports if you are running singlemode fiber? I see fiber channel ones used, I see mention of 850nm, but can't find any mention of single mode breakout cables.

I'm expecting a couple of 7250-24 tomorrow or friday for home lab, and trying to plan the setup to stack them. I'm having trouble finding an explanation as to how to do that. I've read that I can use a 2-node ring or linear, and it doesn't seem to matter (I've got 4 twinax cables to use). What has me confused is whether I need to set up a stack trunk, or if it's 'good enough' to just connect the appropriate ports, and run the stack setup wizard. Any de-confusion much appreciated :)

I've just recently acquired a ICX 6450-48 and it seems the one fan never spins down.

Running the command "dm fan-speed" results in:
Code:
All fans in Low speed (0xff)
Which leads me to believe "low" speed is 100%. Is this normal?
This occurred before and after I upgraded the firmware as directed in the OP.

I've unplugged the fan and the temps are rising very slowly (about 61.5C now). I hope it'll level off soon, this would make a cool fanless switch.

mtp to os2?
Would need to know what connector is on the QSFP. Ones from Brocade that I have are MTP. I've seen some with LC.

noob question re hitting the B key (during firmware flash of new switch)

Switch: Brocade 7150-c12p ; using factory console cable plugged into ancient laptop's serial port.

I am trying to follow instructions and pound-the-b-key while inserting power cord in the 7150; and it keeps booting into the OS and not the boot menu I am expected (per instructions).

I also recall a year ago having similiar problems hitting-the-b-key with a 7250.

in short, wtf am I doing wrong? (or what is the precisely anal method for "pound-the-b-key" and insertion of power cord.

hit b a bunch of times in the first 5-10 seconds of booting not just when you connect the power. Make sure your console settings are 9600 8-none-1-none. The no flow control is important.

It does make a big difference in a two node stack if you run ring or linear and 2-node should always be linear. This is the only time you should ever run linear stacks. What you want to do is run version of 8.0.90 or newer (8.092b is solid for me) then follow the RUCKUS FastIron Stacking Configuration Guide under the section "'Building a Two-unit Stack with a Linear-topology Trunk Using Stack Interactive-setup". The example in the guide is a pair of 7250. Make sure you have the 10gig licenses added first and interfaces configured for 10gig.

If you actually want to breakout to 4x10g this is probably what you want but it is very expensive.
E40G-QSFP-LR4-INT40GBASE-LR4 QSFP+ to 4 SFP+ optic (LC), for up to 10 km over SMF
