The EPC is looking for it's operating system on the workstation's ftp server: You have to properly set up the ftp server and the user "micromass", the EPC will constantly reboot and try to connect.
Leave your e-mail address and I'll send you an instruction document how to do that.

Dear Colleagues,
I have the same problem with eternal reboot... And I do not know what to do. Can you send me the same instructions? I have a Synapt G1 HDMS instrument, but maybe it will be suitable for me too...
At my first attempt EPC didn't even try to boot because of the Lan Boot Agent (PXE-E05 error), I found a similar motherboard, but now it goes to eternal reboot..
My e-mail: TemerdashevAZ@gmail.com

Thank you!
And one more strange thing - I can ping IP 127.0.0.1 connection, but the right one should be 64.1.1.2 according to the manual...
127.0.0.1 is often the "host" ip address. In other words, the computer is pinging iteself.

Exactly my situation :-) Finally, my EPC responds to ping 64.1.1.2, but there are still the same errors in MassLynx. That's strange...
I also can access ftp and there are no issues when I'm trying to access the vxworks folder, but nothing changed...
You mentioned a new motherboard. IIRC there is some firmware chip on the original mainboard which tells the EPC where to load the vxworks. Did you transfer it to the new motherboard? Sorry our Quattro Ultima is out of service since more than one year, I can't have a look into it any more...

Thank you for your response!
I changed back the motherboard (the original one is installed again) to avoid issues with the integrated chip :-) In the boot process of EPC PXE-E05 error (LAN adapter's configuration is corrupted or has not been initialized. The boot agent cannot continue) appears (I connected the monitor to EPC via VGA cable). But at the same time, it established a connection and I can see properties send and receive packages. But the system still didn't boot completely. The boot sequence in BIOS is: 1- HDD, 2- Floppy.
I also disabled firewall (in settings and the second step was barbarian - I disabled it in services), but it changed nothing :-(
