Setting up Brocade FCX & ICX6610


If you haven't already, visit the Brocade Overview page to download the latest guide package and get it ready to be served via TFTP - this unified package includes all the latest firmware, licenses, and documentation.

Connect to the serial/console port using a program like Putty (9600 8N1), then connect the management ethernet port to your network (do NOT use any of the regular switch ports yet).

Power on the switch while watching your serial terminal - it will have a prompt saying Hit b to enter the boot monitor - press b quickly and you'll be dropped into the bootloader prompt, now we can upgrade the software. If you missed the prompt and it boots the OS instead, pull power and try again.

At the boot prompt, we need to give it a temporary IP in the subnet of your network, so it can talk to your TFTP server. This IP will not be used again after it leaves the bootloader. Replace the IP in the example below with an unused IP on your subnet:

ip address
Now we can update the bootloader. Replace the IP with the IP of your tftp server:
copy tftp flash ICX6610-FCX/grz10100.bin boot

After a few seconds it should finish, then we can flash the main OS. Replace the IP with the IP of your tftp server:

copy tftp flash ICX6610-FCX/FCXR08030u.bin primary
It will take a little longer. When it finishes, we need to erase the current config & any passwords, then tell the switch to reboot into the full OS:

factory set-default
If you get "Unknown command factory"

If you get an Unknown command factory error, this means your switch has a very old bootloader. In that case since we just flashed the latest bootloader already, we just have to tell the switch to reset to load it. Then in the new bootloader the command will work:

#hit b a bunch so it drops into the bootloader again
#now it's booted the latest bootloader, so the command will work:
factory set-default
Let the switch boot fully and move to the next section

If your switch still claims to be a stack member after booting

If your switch says that it's part of a stack even after the above factory reset, you'll need to unstack it before being able to configure and update it. You'll see several prompts when booting that it's a stack member. You can unstack your switch by running the following command:

stack unconfigure clean
# hit y at the prompt
You can then continue the guide as normal when it finishes resetting

Initial Configuration

Now that it's booted into the full OS you may get TFTP timed out errors in the console, this is normal. just hit enter until they go away. We'll fix that in the next section. Now to make any changes we must enter the enable level:

Now we enter the configure terminal level to make config changes:

configure terminal
Now we turn off the DHCP client, so it doesn't automatically grab an IP and look for a TFTP config (the cause of the earlier timeout messages):
ip dhcp-client disable
Now we give the switch its permanent IP address. By default, all ports are in VLAN 1, so it will behave like a typical switch. First we need to give VLAN 1 its own virtual interface:

vlan 1
router-interface ve 1
Now we need to assign that virtual interface an address. Choose an IP that is unused in your subnet, and out of your DHCP server range (ping it first to be sure it's unused):
interface ve 1
ip address
write mem
Now your switch is set up for basic switching, and has an IP address you can use to manage the switch. But you're not done yet!

Note: You should now unplug your ethernet connection from the dedicated management port, and instead connect it to any of the regular switch ports. If you skip this, the rest of the guides will not work.

Update PoE Firmware

If your switch is the PoE model, you need to update the PoE controller firmware. If it's a non-PoE model, skip this section. Assuming you completed the previous section and the switch now has in-band network access (one of the regular ports are connected), just do the following:

inline power install-firmware stack-unit 1 tftp ICX6610-FCX/fcx_poeplus_02.1.0.b004.fw
#after a few seconds, hit enter to return to cli
#save changes you made from the previous section
write memory
#reload the switch
#you'll probably get a message that it hasn't finished. it can take up to 10 minutes
#run "show log" occasionally to monitor the update progress
#try the "reload" command again once it's reached 100%
#once you've rebooted back into the OS:
configure terminal
Now you have the latest PoE firmware, and can continue on.

Further Configuration

You now have a bare minimum setup on your switch, and the latest firmware. To continue with further configuration including securing and naming the switch, setting up SSH and Web UI access, PoE commands etc, please continue to the ICX6xxx Series Config Page. Don't forget to return here when you're finished for the stack port, noise, and licensing info below if you need them.

ICX6610 Stack Ports

This optional section outlines how to use the ICX6610 rear "stacking only" QSFP+ ports as regular data ports instead. Note that two of the QSFP+ ports are 40gbE only, and the remaining two are 4x 10gbE breakout only. You must be on the latest FastIron release for this to work (so, follow the above update instructions if you haven't).

Removing Stack Configuration

There are going to be some stacking commands automatically put in your configuration, so we need to remove them. To see what you need to remove, show the config:

show run
Towards the top you should see a stacking related block similar to the below:
stack unit 1
  module 1 icx6610-48-port-management-module
  module 2 icx6610-qsfp-10-port-160g-module
  module 3 icx6610-8-port-10g-dual-mode-module
  stack-trunk 1/2/1 to 1/2/2
  stack-trunk 1/2/6 to 1/2/7

We need to remove the two stack-trunk lines. Notice that they are under the stack unit 1 level, so you need to enter that CLI level first. While we're in there, we'll also disable stacking:

conf t
stack unit 1
no stack-trunk 1/2/1 to 1/2/2
no stack-trunk 1/2/6 to 1/2/7
stack disable
write mem
Now show the config:
show run
There should no longer be any stack-trunk commands, or any commands referencing stack ports. That's pretty much it! You can now use the ports on the rear as normal. However, see the next section on how they are laid out.

Port Layout

Keep in mind two of the rear ports are 4x 10gbE breakout only, and the remaining two are 40gbE only. The two 40gbE-only ports will NOT run at 10gbE (for instance with a QSFP to SFP+ adapter), so use these two for 40gbE links only. The extremely professional diagram below shows the port config and their associated port numbers in the OS:

Noise Info (ICX6610)

The ICX66610 power supply bricks came in 3 revisions: A, B, and C. These will have an affect on how loud the switch is. Generally with an A revision PSU anywhere, even combined with a B or C revision in the other PSU slot, the PSU fans will run louder.

The switch will be much quieter if you can find and run B and/or C revision bricks. There's no difference noise wise between B and C. Most sellers do not list the revision so you have to check the ebay pictures for the revision marking.

Also, it seems the PSU and fan tray position also affect fan speed. If you are running 1 PSU and fan tray, position them in the furthest left slots, when looking at the switch from the rear. If you have 2 PSUs and 1 fan tray, position the fan tray in the furthest left fan tray slot when looking at the rear of the switch.

Licensing Info

Like other EoL ICX6xxx series switches, the ICX6610 requires license file unlocks for 10gbE port functionality as well as some advanced software features. These licenses are no longer sold. To prevent e-waste and save these from landfills, I am providing free unlocks for use in a homelab or personal environment. Once you've finished the update and configuration process, proceed to the ICX6610 Licensing section to fully license and unlock your switch. If you have an FCX, you can use the FCX Licensing section.
