Hi, just setting up the 7800vdox and am having a problem with the Ethernet ports,
only 3 powered up and the 4th is powered off.
how do I turn the 4th one on.
any help would be greatly appreciated.

It appears that they are auto detecting so a reply is not required.
The socket must be damaged, time to return it.

Cheers all.
