The downgrade is the same as the upgrade process. You need a TFTP server that the switch can pull from, you'll need the firmware in the targetted folder that the TFTP server is targetting and you'll need the switch on the network so it can see the TFTP server.
Once you have all that then you...

enable
copy tftp://<IP>/<file name>.bin backup
or
copy tftp://<IP>/<file name>.bin image1 (or image2)

then (and I can't remember the command right now) do something like system boot image1 or system boot backup
then
reload.

I'd have to look at my notes. I keep notes for stuff like this because it's just not possible to remember everything.

But if you can get a TFTP server up and going I'll get you my notes.

Apparently, the switch is still unable to communicate with anything on my network. TFTP server is functional, and accessible, I've tested from a different device on my network. Getting an immediate "File transfer failed!"

Lights are working?
Have you tried setting the management port IP and logging in through the management port?
Mind you the management port and the console port are two different ports.

Lights are working, showing link and activity. Power lights are green showing both psus are active. I assumed this section was setting the management ip:
Set IP
network protocol none
network parms <IP> <Subnet> <Gateway>
If thats not the case, no.

There is actually a separate IP address for the management interface so that one can disable management to every other port other than the management port.
Here's a thread that talks about management...
Quanta LB4M Switch Setup

I know how to configure it via the web gui but I'm not sure about the CLI. I believe it's called the service port

So maybe....
serviceport protocol none
serviceport ip (IP) (Sub) (GW)

then give it a try?

Dropbox - lb4m_flash V66 1.1.0.8.zip

Dropbox - lb4m.5.13.12.14 Routing Enabled 1.0.2.17.zip

Dropbox - lb4m.pdf

For anyone that wants them and for a limited time.

I currently don't know of any other firmwares for the LB4M
There's also 1.0.2.17 without routing enabled, should someone want the Web UI but for some reason not want routing.

I had a discussion a page back about with @aj84 as to whether there could be a scenario where routing was bad to have if not being used. There isn't any known disadvantage, but if someone definitely doesn't want routing and definitely does want the Web UI, I suppose it would make sense to install the non-routing 1.0.2.17 to keep things simple(r).

Here's a quote of the original post with the download link for the non-routing 1.0.2.17 FW:

The file names on mine are H-Search-Ent-esw-lb4m-qc8541-V66S-CS-QHr1v1m1b8.opr and Ent-esw-xgs3-LB4M-dni8541-VSM-QHr1v0m2b17.opr and can be downloaded from this link.
The filenames in that download are strangely named and not immediately identifiable, so here's a quote from @aj84 describing which filename holds the 1.0.2.17 FW:

Filename is "Ent-esw-xgs3-LB4M-dni8541-VSM-QHr1v0m2b17.opr"...just rename it to "l4bm.1.0.2.17.bin" or "image.bin" and flash it using tftp. (Look at the command Matt C used)

Found a 1.0.3.2 on some of my newest ebay purchases.
Dropbox - 1.0.3.2_firmware.bin

I had a weird issue while running it at an event. On several switches, management would completely stop responding but switching still functioned properly. They would function normally after a power cycle. I have not seen this happen in the home lab though.

Thanks for the new FW. Does this have the Web UI? If so, that'd theoretically make it a better option than 1.0.2.17. Ie 1.0.3.2 would be the highest FW version available with a UI.

If it doesn't have UI, then 1.1.0.8 is presumably still preferable as being the latest known version.

That issue you describe sounds a bit odd though!

I've just been looking at all the FW files I have for the LB4M, and their sizes:
Code:
8770004    lb4m.1.0.2.17.bin
8770348    lb4m.1.0.3.2.bin
9373712    lb4m.1.1.0.8.bin
10550936   lb4m.5.13.12.14.1.0.2.1.7.routing.bin
So 1.0.3.2 and 1.0.2.17 are practically identical in size. 5.13.12.14 with the routing is the largest of the lot, unsurprisingly.

But what I do find unexpected is that 1.1.0.8 is ~500kb larger than its 1.0.x.x predecessors, despite supposedly not having the Web UI.

I wonder what takes all that extra space in 1.1? And maybe the Web UI is in fact still in there, just disabled by default - as otherwise it'd must be an even larger amount of extra new data in 1.1.0.8 if it's also lacking the UI files.

Yeah, same as 1.0.2.17. VxWorks 5.5.1 still, not sure whats been added though.
Code:
    Runtime Version: 5.5.1
    BSP version: 1.2/0
    Created: Dec  9 2014, 12:20:33

1.1.x.x firmwares are based off VxWorks 6.6 whereas 1.0.x.x firmwares are based off VxWorks 5.5.1.

Cool, thanks. Is that difference in VxWorks version significant, to your knowledge? Are there any known benefits to 6.6 vs 5.5 that would make the 1.1 FW more attractive in this application?

+1 for TheBloke's question

And thanks for the other firmware posts.
Someone should make a sticky with the available firmwares
I just downloaded what you guys posted and added it to my list

Everything I have. I was just thinking it should be made a sticky as the firmwares can be hard to find. The only place I've really easily found them was on this forum and it seems what I do and what this forum is in sync, LOL.
Great group of guys on this forum!

Hi,
I recently purchased a LB4M switch which came with V1.1.0.8 both images. All has been great up to the point I decided to try 1.0.2.17 which was going well until I updated the boot code which caused an error and now i am in the situation where the switch will not boot. I presume for some reason the boot prom has been corrupted so i am hoping there a fix or have a just bought myself a door stop?

Any advice would be appreciated.

Regards
//\//\ ..... ;)

Connect to the console via a serial port. You will have to do this to tell the switch to boot to the other boot image.
During the boot up you'll see the 2 options come up, but just momentarily. You will have to be fast to hit the option you want then hit enter and I can't remember which option you want off the top of my head and don't have a spare switch to throw on the bench to check.
The switch should at least get that far before it freezes.

I have done this already and used x-modem to update the firmware, which went well. Problem started after
2: start boot menu> option 7 update boot code..... it started to update boot code crashed then disconnected my com port session. Now the switch shows no activity on console port at all and the fans are at full speed.

I tested the connection on another switch Dell 6248p via coms port and all is well with my connection setup to that switch.

thanks again for the fast reply.

So you're not getting anything via the console port?
The fans really don't mean anything other than the switch has not completed it's boot up. Once completely booting it'll slow the fans down, but not before.
