EX 8000 power light flashing green

> [...] the Power light keeps flashing green [...]

   I know nothing about the EX8000, and I didn't see the documentation
mention a flashing power indicator, but on typical router models, that
would indicate corrupt firmware.

   You may be a candidate for the TFTP recovery scheme.  See, for
example:

   For a typical router, the default LAN IP address is "192.168.1.1",
or, for a modem+router, "192.168.0.1".  According to the EX8000 User
Manual, its default IP address "192.168.1.250".  If that holds when its
brain is fried, then you'd need to specify that address instead of one
of the ".1" addresses (which is normally suggested in the instructions)
when attempting the TFTP firmware load.

> [...] I just unplugged the device [...]

   That should be a pretty safe operation, but sometimes a transient
event can disturb a gizmo like this.
