I got a Juniper EX2200 switch which is unable to boot, prior to a corrupted flash. The JTAC support is expired and i tried almost everything to get it working again. I read an article about "Running JunOS directly from an USB stick", but there was no explanation/instructions on how to do this.
Is it possible to do this and how?
Yes, you can boot JUNOS from a USB drive, and an EX2200 will work.
Booting an EX Series Switch Using a Software Package Stored on a USB Flash Drive
Follow the documentation and it should work fine. Chances are your flash isn't permanently corrupt so you can reinstall JUNOS and get everything back in working order.
loader> install --format --external file:/// again. I'm able to access Junos now. But after 2 reboots it went on again, but this time i fixed it again with the above command and were able to update the boot loader.
