What can I do if the version is below 2.6.2?  
I have an ePMP1000, version 2.6, when I try to update to 2.6.1 during the writing flash itself rebooted. Now it does not boot, it recyclic rebooted after 40-50 seconds, does not try to get the address by DHCP, it also does not respond at addresses 192.168.0.1 and 169.254.1.1, and does not show MAC-address on&nbsp;port switch. I tried to do a reset by turning off and turning on power for 3-5 seconds 4 times - it has no changes.

What can I do about it?

Hi,&nbsp;  
&nbsp;  
Unfortunately, if the device wasnt running at least release 2.6.2, TFTP recovery is not possible. If the device does not bootup and is in a rolling reboot, the flash is most likely corrupted and the device is not operable. You will have to use another device in its place.&nbsp;

Hi Fedor  
Unfortunately it is not well explained.&nbsp;The proposed steps do not work.&nbsp;
