I was updating a ePMP 1000 and the power went off and the update didnt finish. When the power came back I lost connection to the ePMP and the lights are stuck on. Tried hard reset and didnt work
Please try to recover it via TFTP.
Please see the following for details:
As Fedor says, setup a tftp boot network and follow the instructions.
Make sure your firewall is disabled or it wont work properly.
If using windows I highly suggest tftpd, its easy and does everything you need in one package.
